It happens at the work face, with the profile already erected or resting in place, often at height, surrounded by dust, wind and awkward postures. That context changes the disc choice completely: it is not enough for it to remove metal, it has to do so with <strong style=\"color:#111;font-weight:800;\">safety<\/strong> and in a repeatable way when the operator is far from the workshop.<\/p>\n<p style=\"margin:0 0 18px;\">The typical task is dressing a field <strong style=\"color:#111;font-weight:800;\">weld bead<\/strong>, removing the burr left by a cut or an oxy-fuel cut, levelling the joint between two profiles before bolting, or leaving the surface ready for the primer. Each of those operations calls for a different balance of removal, control and <strong style=\"color:#111;font-weight:800;\">finish<\/strong>, because a coat of paint or a galvanised layer almost always follows and exposes any deep mark.<\/p>\n<p style=\"margin:0 0 18px;\">Unlike series manufacturing, the site operator cannot try three different references or swap the disc every two parts. They need a <strong style=\"color:#111;font-weight:800;\">stable reference<\/strong> that solves most cases with one angle grinder, that does not force them to carry boxes of different consumables, and that withstands field conditions without behaving erratically.<\/p>\n<p style=\"margin:0 0 22px;\">Grinding and cutting are complementary but distinct operations: cutting separates the profile and grinding removes metal and dresses the joint. If what you need is to sever or chop profiles rather than dress beads, it is worth reviewing the dedicated content on <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/blog\/discos-abrasivos\/discos-corte-construccion\/\">cutting discs for construction<\/a> separately; this article focuses on <strong style=\"color:#111;font-weight:800;\">on-site dressing<\/strong>, not on the chopping operation.<\/p>\n<figure style=\"margin:24px 0 30px;padding:14px;background:#f9fafb;border:1px solid #e8ebef;\">\n    <img decoding=\"async\" style=\"display:block;width:100%;height:auto;aspect-ratio:3\/2;object-fit:contain;background:#ffffff;\" src=\"https:\/\/www.abrasteel.com\/images\/disco-desbaste-basic.jpg\" alt=\"Abrasteel construction grinding disc for dressing profiles and weld beads on a steelwork site\"><figcaption style=\"margin:10px 0 0;color:#555f66;font-size:15px;\">On site, grinding must combine removal, control and safety at the work face before the primer.<\/figcaption><\/figure>\n<h2 id=\"claves-construccion\" style=\"margin:clamp(38px,9vw,54px) 0 18px;padding-bottom:10px;border-bottom:2px solid #e8ebef;color:#023a51;font-size:clamp(24px,6vw,30px);line-height:1.18;font-weight:700;\">7 keys to choosing construction grinding discs<\/h2>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">1. Material and hardness of the profile<\/h3>\n<p style=\"margin:0 0 16px;\">Several materials coexist on a steelwork site: <strong style=\"color:#111;font-weight:800;\">structural carbon steel<\/strong> in most profiles, stainless steel in handrails and exposed elements, and galvanised parts already treated when they arrive for assembly. Each reacts differently to grinding, and <strong style=\"color:#111;font-weight:800;\">galvanised<\/strong> steel in particular demands care so you do not strip more zinc than necessary in the area that later has to be touched up.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">2. Amount of burr to remove<\/h3>\n<p style=\"margin:0 0 16px;\">Cleaning off a loose spatter is not the same as grinding down a full bead or levelling a joint with a lot of excess metal. Heavy removal at the work face prioritises robustness and <strong style=\"color:#111;font-weight:800;\">removal capacity<\/strong>; for a light pass it may be better to move on afterwards to <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/en\/abrasive-discs\/blade-discs\/\">flap discs<\/a> rather than force the grinding disc into a job that is not its own.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">3. Burr type: cut, oxy-fuel or field welding<\/h3>\n<p style=\"margin:0 0 16px;\">The origin of the burr sets the aggressiveness you need. <strong style=\"color:#111;font-weight:800;\">Oxy-fuel<\/strong> burrs usually come with hard, well-adhered slag; field welding leaves spatter and excess bead height; a chop-saw cut leaves a cleaner sharp edge. Identifying where it comes from avoids spending more abrasive than needed and stops you reaching for a disc that is too aggressive for a minor pass.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">4. Pressure and machine on site<\/h3>\n<p style=\"margin:0 0 16px;\">In the field you almost always work with a <strong style=\"color:#111;font-weight:800;\">portable angle grinder<\/strong> and in uncomfortable postures: at height, on scaffolding or with the profile already erected. A disc that only performs under heavy pressure generates fatigue, vibration and risk, exactly where the operator has least support, so managing exposure to <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.hse.gov.uk\/vibration\/hav\/index.htm\" target=\"_blank\" rel=\"noopener nofollow\">hand-arm vibration<\/a> matters. A regular response that does not force you to lean on the machine is what you want.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">5. Next stage: primer, paint or galvanising<\/h3>\n<p style=\"margin:0 0 16px;\">Grinding on site is almost never the end. Behind it comes the <strong style=\"color:#111;font-weight:800;\">primer<\/strong>, the finish paint, the galvanising touch-up or the fitting of the neighbouring part. If the disc leaves deep grooves or burns the surface, that mark reappears under the paint and forces you to sand again. Choosing with the later coat in mind cuts rework in an environment where climbing back up to re-dress is expensive.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">6. Disc service life in field conditions<\/h3>\n<p style=\"margin:0 0 16px;\"><strong style=\"color:#111;font-weight:800;\">Service life<\/strong> matters more on site than in the workshop, because restocking a consumable at the work face is not always immediate. A disc that burns through quickly forces the operator down off the scaffold, hunting for a replacement or stopping the job. The right reference holds its performance across a wide part of its life and avoids constant changes in the middle of a task at height.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">7. Cost per operation on site<\/h3>\n<p style=\"margin:0 0 16px;\">At the work face, cost is not measured per disc bought but per <strong style=\"color:#111;font-weight:800;\">metre of bead dressed<\/strong> or joint left ready. You have to add up consumption, operator time, trips to the work face, rework from marks under the paint and downtime. A disc that costs a little more per unit pays off if it cuts the number of climbs and the later touch-up.<\/p>\n<h2 id=\"aplicaciones-construccion\" style=\"margin:clamp(38px,9vw,54px) 0 18px;padding-bottom:10px;border-bottom:2px solid #e8ebef;color:#023a51;font-size:clamp(24px,6vw,30px);line-height:1.18;font-weight:700;\">Grinding applications in structural steelwork<\/h2>\n<p style=\"margin:0 0 16px;\">On-site grinding operations are fairly specific and recur on almost every structural, metalwork and field-boilermaking job. Dressing a weld bead made in place, removing slag and spatter, lightly bevelling a plate, levelling the joint of two profiles and leaving the surface prepared before the <strong style=\"color:#111;font-weight:800;\">primer<\/strong> are the most common. They all share one context: they are carried out far from the workshop, with the profile already in position or about to be fitted.<\/p>\n<p style=\"margin:0 0 16px;\">Each operation has a typical problem and an associated abrasive decision. Sorting them out helps the operator avoid using the same aggressive disc for everything and stops them forcing the <strong style=\"color:#111;font-weight:800;\">angle grinder<\/strong> through a pass that called for a finer abrasive. The table below sums up the most frequent cases at the work face.<\/p>\n<div style=\"overflow-x:auto;margin:24px 0;border:1px solid #e8ebef;\">\n<table style=\"width:100%;min-width:680px;border-collapse:collapse;background:#fff;\">\n<thead>\n<tr>\n<th style=\"padding:14px;background:#023a51;color:#fff;text-align:left;font-weight:800;border-bottom:1px solid #e8ebef;\">On-site operation<\/th>\n<th style=\"padding:14px;background:#023a51;color:#fff;text-align:left;font-weight:800;border-bottom:1px solid #e8ebef;\">Typical problem<\/th>\n<th style=\"padding:14px;background:#023a51;color:#fff;text-align:left;font-weight:800;border-bottom:1px solid #e8ebef;\">Abrasive decision<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Dressing a field bead<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Excess weld height and spatter.<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Grinding with controlled removal.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Removing oxy-fuel slag<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Hard slag adhered to the edge.<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Robust disc that bites safely.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Levelling a joint before assembly<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Interference or step between profiles.<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Grinding with pressure control.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:14px;vertical-align:top;\">Preparing before primer<\/td>\n<td style=\"padding:14px;vertical-align:top;\">Marks or excessive roughness.<\/td>\n<td style=\"padding:14px;vertical-align:top;\">Move to flap discs to even out.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Dressing field weld beads<\/h3>\n<p style=\"margin:0 0 16px;\">This is the most repeated operation in field structures. After an in-place weld, the bead is usually left with excess height, spatter and the odd irregular spot that has to be ground down before the joint is signed off. The disc has to remove that excess without biting into the base metal or rounding an edge that must stay square. On exposed joints, the <strong style=\"color:#111;font-weight:800;\">finish<\/strong> also directly conditions how the result looks under the final paint.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Removing slag and spatter<\/h3>\n<p style=\"margin:0 0 16px;\">Oxy-fuel <strong style=\"color:#111;font-weight:800;\">slag<\/strong> and weld spatter are hard, localised and often stuck to the edge of the profile. Here the disc needs to bite safely at a specific point without the operator having to bear down freehand in a forced posture. Removing these deposits properly is essential so the primer grips and does not flake off over time.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Light bevelling and levelling joints<\/h3>\n<p style=\"margin:0 0 16px;\">Before bolting or welding two profiles, you sometimes have to lightly bevel an edge or level a <strong style=\"color:#111;font-weight:800;\">joint<\/strong> with a step. This is precision grinding, not brute removal: the aim is for the parts to seat with no gap or interference. A disc that is too aggressive takes off more metal than planned and forces you to fill afterwards, which on site raises cost and delays assembly.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Preparing before primer or paint<\/h3>\n<p style=\"margin:0 0 16px;\">The last common application is leaving the area ready for the first coat. Here grinding must remove surface rust, weld residue and excess roughness without leaving grooves that show through under the <strong style=\"color:#111;font-weight:800;\">paint<\/strong>. When fine uniformity is the goal, the logical move is to close the preparation with a flap disc and keep the grinding disc for the initial removal.<\/p>\n<h2 id=\"errores-construccion\" style=\"margin:clamp(38px,9vw,54px) 0 18px;padding-bottom:10px;border-bottom:2px solid #e8ebef;color:#023a51;font-size:clamp(24px,6vw,30px);line-height:1.18;font-weight:700;\">Common grinding mistakes on site<\/h2>\n<p style=\"margin:0 0 16px;\">The most repeated mistake at the work face is using a single very aggressive disc for everything, from removing slag to preparing a surface that will be painted. That shortcut saves carrying consumables, but it leaves deep marks that reappear under the primer and force a <strong style=\"color:#111;font-weight:800;\">rework<\/strong> that at height costs twice the time.<\/p>\n<p style=\"margin:0 0 16px;\">Another frequent failing is neglecting safety in field conditions: working without a stable hold on the part, with incomplete guarding or forcing the posture at height. On site, <strong style=\"color:#111;font-weight:800;\">dust<\/strong>, wind and lack of support raise the risk, and a poorly chosen disc that demands extra pressure makes that exposure worse. It is worth keeping the wheel guarding intact, as bodies such as <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.osha.gov\/laws-regs\/regulations\/standardnumber\/1910\/1910.215\" target=\"_blank\" rel=\"noopener nofollow\">OSHA<\/a> require for abrasive wheels, and following recognised guidance on the <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.hse.gov.uk\/pubns\/priced\/hsg17.pdf\" target=\"_blank\" rel=\"noopener nofollow\">safe use of abrasive wheels<\/a>.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Confusing grinding with cutting on site<\/h3>\n<p style=\"margin:0 0 16px;\">Using a grinding disc to sever a profile, or a cutting disc to dress a bead, is a frequent error when you want to work fast with the same machine. Each disc works in its own way: the grinding disc removes metal with its face, the cutting disc separates with its edge. Crossing the uses is <strong style=\"color:#111;font-weight:800;\">unsafe<\/strong> and wears the consumable out well before its time.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Ignoring the galvanising<\/h3>\n<p style=\"margin:0 0 16px;\">Grinding a galvanised part as if it were bare steel strips off more <strong style=\"color:#111;font-weight:800;\">zinc<\/strong> than necessary and leaves an area unprotected against corrosion. On site it is wise to limit grinding to the essential zone and to plan the galvanising touch-up afterwards, especially on elements that will stay exposed to the weather for the whole life of the structure.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Leaving a deep mark before painting<\/h3>\n<p style=\"margin:0 0 16px;\">Grinding down quickly with a very aggressive disc and not closing the preparation leaves grooves the paint will not hide. The <strong style=\"color:#111;font-weight:800;\">finish coat<\/strong> can even highlight those grooves, and the result looks worse than before dressing. The right way is to remove with a grinding disc and finish with a finer abrasive when the joint is exposed or painted.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Masking an upstream problem with grinding<\/h3>\n<p style=\"margin:0 0 16px;\">When a joint always arrives with too much excess metal, or a part with too much burr, grinding fixes the symptom but not the cause. If the problem comes from the <strong style=\"color:#111;font-weight:800;\">cut<\/strong> or the field welding, it is better to correct that stage first: reducing spatter or refining the bead saves more work than swapping the grinding disc over and over.<\/p>\n<h2 id=\"productos-construccion\" style=\"margin:clamp(38px,9vw,54px) 0 18px;padding-bottom:10px;border-bottom:2px solid #e8ebef;color:#023a51;font-size:clamp(24px,6vw,30px);line-height:1.18;font-weight:700;\">Abrasteel discs for construction<\/h2>\n<div style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(min(100%,250px),1fr));gap:18px;margin:24px 0;\">\n<div style=\"border:1px solid #e8ebef;background:#fff;padding:16px;\"><img decoding=\"async\" style=\"display:block;width:100%;height:clamp(150px,44vw,185px);object-fit:contain;background:#f9fafb;margin:0 0 14px;\" src=\"https:\/\/www.abrasteel.com\/images\/disco-desbaste-basic.jpg\" alt=\"Abrasteel grinding disc for dressing profiles on a construction site\"><\/p>\n<h3 style=\"margin:0 0 8px;color:#023a51;font-size:clamp(19px,5vw,21px);line-height:1.25;font-weight:800;\">Grinding discs<\/h3>\n<p style=\"margin:0 0 10px;color:#555f66;font-size:16px;line-height:1.55;\">Family for <strong style=\"color:#111;font-weight:800;\">dressing weld beads<\/strong>, burrs and slag at the work face.<\/p>\n<p style=\"margin:0;\"><a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/en\/abrasive-discs\/rough-discs\/\">View range<\/a><\/p>\n<\/div>\n<div style=\"border:1px solid #e8ebef;background:#fff;padding:16px;\"><img decoding=\"async\" style=\"display:block;width:100%;height:clamp(150px,44vw,185px);object-fit:contain;background:#f9fafb;margin:0 0 14px;\" src=\"https:\/\/www.abrasteel.com\/images\/disco-de-corte-top-aleaciones-hierro-acero-inoxidable.webp\" alt=\"Abrasteel cutting disc for chopping profiles in construction\"><\/p>\n<h3 style=\"margin:0 0 8px;color:#023a51;font-size:clamp(19px,5vw,21px);line-height:1.25;font-weight:800;\">Cutting discs<\/h3>\n<p style=\"margin:0 0 10px;color:#555f66;font-size:16px;line-height:1.55;\">To <strong style=\"color:#111;font-weight:800;\">sever and chop profiles<\/strong> before grinding on site.<\/p>\n<p style=\"margin:0;\"><a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/blog\/discos-abrasivos\/discos-corte-construccion\/\">View cutting for construction<\/a><\/p>\n<\/div>\n<div style=\"border:1px solid #e8ebef;background:#fff;padding:16px;\"><img decoding=\"async\" style=\"display:block;width:100%;height:clamp(150px,44vw,185px);object-fit:contain;background:#f9fafb;margin:0 0 14px;\" src=\"https:\/\/www.abrasteel.com\/images\/disco-de-corte-xtrem-para-aceros-inoxidables.jpg\" alt=\"Abrasteel XTREM disc for stainless steel on site\"><\/p>\n<h3 style=\"margin:0 0 8px;color:#023a51;font-size:clamp(19px,5vw,21px);line-height:1.25;font-weight:800;\">Stainless solution<\/h3>\n<p style=\"margin:0 0 10px;color:#555f66;font-size:16px;line-height:1.55;\">Reference for <strong style=\"color:#111;font-weight:800;\">exposed stainless elements<\/strong> such as handrails and metalwork.<\/p>\n<p style=\"margin:0;\"><a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/en\/abrasive-discs\/rough-discs\/\">View range<\/a><\/p>\n<\/div><\/div>\n<p style=\"margin:0 0 16px;\">To review the whole range, the <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/en\/abrasive-discs\/rough-discs\/\">Abrasteel grinding discs<\/a> page sorts the references by removal level and material, and to prepare the surface after dressing it can be combined with cleaning solutions such as <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/en\/abrasive-discs\/clean-strip-discs\/\">Clean Strip<\/a>.

When we advise on construction we do not only ask which disc is used: we ask which profile is being erected, which joint has to be dressed, which <strong style=\"color:#111;font-weight:800;\">angle grinder<\/strong> is on hand, what finish is expected and under what field conditions the job runs.<\/p>\n<p style=\"margin:0 0 16px;\">With that information we help define a short, stable selection: a grinding disc for on-site removal, a cutting solution to chop profiles and the finishing abrasive to leave the surface ready before the <strong style=\"color:#111;font-weight:800;\">primer<\/strong>. If you manage purchasing or coordinate the work faces of a project, we can tune references, formats and lead times to your real volume of work.

On exposed joints the finish also matters, because it conditions the result under the final paint, so the preparation is usually closed with a finer abrasive.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">What is the difference between grinding and cutting on site?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">The cutting disc severs or chops the profile working with its edge, and the grinding disc removes metal and dresses the joint working with its face. They are complementary but not interchangeable operations: using one for the other is unsafe and consumes the disc well before its time.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">How do I grind without damaging the galvanising?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">By limiting grinding to the essential zone so you do not strip more zinc than necessary, and by planning the galvanising touch-up in that area afterwards. On elements that will stay exposed to the weather it is key not to leave bare steel unprotected against corrosion.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">How do I leave the surface ready before the primer?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">By removing surface rust, slag and weld residue with the grinding disc, then closing with a flap disc to even out without leaving deep grooves. If the removal leaves a mark, that mark reappears under the paint and forces you to sand again, with the extra cost of going back to the work face.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">What grit or hardness should I pick for grinding in construction?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">It depends on the profile material and the finish sought: a more aggressive abrasive removes faster but leaves more mark, and a finer one levels the joint better. On site it is worth fixing a stable reference by typical profile and later stage, so you do not have to carry different consumables to the work face.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">What safety precautions apply when grinding at height?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">Secure the part whenever possible, use full protection against dust and projections, keep the wheel guard in place and avoid forced postures that reduce control of the grinder. A poorly chosen disc that demands extra pressure makes the risk worse, so a regular-response reference that does not force you to lean on the machine is preferable.<\/p>\n<\/div>\n<\/details><\/div>\n<div data-abrasteel-sticky-cta=\"true\" aria-label=\"Acciones r\u00e1pidas de Abrasteel\" style=\"position:fixed;right:max(12px,env(safe-area-inset-right));bottom:max(12px,env(safe-area-inset-bottom));z-index:9999;width:min(260px,calc(100vw - 24px));max-height:calc(54vh - 24px);background:#ffffff;border:1px solid rgba(2,58,81,.16);box-shadow:0 18px 44px rgba(2,58,81,.20);overflow:auto;\">\n<div style=\"height:6px;background:linear-gradient(90deg,#cc0000 0%,#cc0000 38%,#023a51 38%,#023a51 100%);\"><\/div>\n<p><button type=\"button\" aria-label=\"Cerrar aviso\" onclick=\"this.closest('[data-abrasteel-sticky-cta]').style.display='none';\" style=\"position:absolute;top:10px;right:10px;z-index:2;width:32px;height:32px;border:1px solid #e8ebef;background:#ffffff;color:#023a51;font-size:18px;line-height:1;font-weight:800;cursor:pointer;\">x<\/button><\/p>\n<div style=\"padding:clamp(12px,3.5vw,16px) clamp(12px,3.5vw,16px) clamp(10px,3vw,14px);\">\n<p style=\"margin:0 0 6px;color:#cc0000;font-size:13px;font-weight:800;letter-spacing:.06em;text-transform:uppercase;\">Abrasteel advice<\/p>\n<p style=\"margin:0 0 8px;color:#023a51;font-size:clamp(18px,4.8vw,20px);line-height:1.18;font-weight:800;\">Grinding for structural steelwork?<\/p>\n<p style=\"margin:0 0 12px;color:#555f66;font-size:clamp(14px,4vw,16px);line-height:1.45;\">We help you fix the reference right at the work face.<\/p>\n<\/div>\n<p><a style=\"display:block;padding:clamp(11px,3.2vw,13px) 14px;background:#cc0000;color:#fff;font-size:clamp(14px,3.8vw,15px);font-weight:800;text-align:center;text-decoration:none;\" href=\"https:\/\/www.abrasteel.com\/en\/contact\/\">Request technical advice<\/a><a style=\"display:block;padding:clamp(11px,3.2vw,13px) 14px;background:#000;color:#fff;font-size:clamp(14px,3.8vw,15px);font-weight:800;text-align:center;text-decoration:none;\" href=\"https:\/\/www.abrasteel.com\/wp-content\/uploads\/2022\/06\/Catalogo2017.pdf\" target=\"_blank\" rel=\"noopener\">Download catalogue<\/a><\/div>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>Technical guide to choosing construction grinding discs: dressing weld beads, removing burrs on site and preparing steel profiles before the primer coat.<\/p>\n","protected":false},"author":1,"featured_media":4284,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[178],"tags":[],"class_list":["post-7793","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-abrasive-discs"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/posts\/7793","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/comments?post=7793"}],"version-history":[{"count":2,"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/posts\/7793\/revisions"}],"predecessor-version":[{"id":8572,"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/posts\/7793\/revisions\/8572"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/media\/4284"}],"wp:attachment":[{"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/media?parent=7793"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/categories?post=7793"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.abrasteel.com\/en\/wp-json\/wp\/v2\/tags?post=7793"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
