Moving loads include trolleys, pallet trucks, site workers walking in a line and material on a trolley; standing loads include scaffold base plates, tool cases, stacked material and equipment stands. Standing loads are almost always more damaging because they act in one place for a long time.<\/p>\n<p>The conversion is straightforward. Take the heaviest standing load, divide it by the area of the footprint in square metres, and that gives the peak pressure. Add a safety factor of at least two to cover dynamic effects, because a load dropped or rolled into position briefly exceeds its static weight. The result is the design load per square metre to specify against.<\/p>\n<p>Write the calculation down and send it with the enquiry. A supplier who can see the load calculation will recommend a board on the basis of it, and will tell you when the requirement is beyond a standard product. A supplier given only a thickness will give you a board at that thickness and leave the responsibility with you.<\/p>\n<h2 id=\"sec-2\">Reading internal load capacity correctly<\/h2>\n<p>Internal load capacity is the load per square metre a panel carries at a stated deflection, and the deflection figure is part of the number rather than a footnote.<\/p>\n<p>Two boards can carry the same load per square metre and behave completely differently, because one allows more deflection before the figure is reached. Deflection is what moves the floor finish underneath, so the allowable deflection is normally limited by the finish rather than by the board.<\/p>\n<p>Common limits in the industry are quoted at 2 mm, 4 mm, 5 mm or 7 mm. For a hard and brittle finish such as thin stone, porcelain or screed, a tighter limit applies because the substrate has little tolerance for movement. For a resilient or floating floor, a larger deflection is usually acceptable because the floor itself is designed to move.<\/p>\n<p>When requesting figures, ask for the capacity at the deflection limit appropriate to the finish you are protecting, and state that limit in the enquiry. This single question removes most of the ambiguity from a board selection and is the fastest route to a specification that will hold up on site.<\/p>\n<p>For terminology and test-method context see <a href=\"https:\/\/www.iso.org\/standards.html\" target=\"_blank\" rel=\"noopener noreferrer\">ISO standards catalogue<\/a>. The guidance on this page is practical site guidance, not a test report or a certificate.<\/p>\n<h2 id=\"sec-3\">Choosing thickness when several loads are involved<\/h2>\n<p>Where standing loads and moving loads differ significantly, specify for the standing load and handle the moving load with a spreader rather than with a heavier board.<\/p>\n<p>A common site pattern is a light trolley route with occasional standing loads at one point. Choosing a board thick enough for the standing load would push the weight and cost of every panel on the route, most of which never need that capacity.<\/p>\n<p>A better arrangement is to use a standard grade along the route and place a spreader plate or a thicker offcut under the standing point. The spreader distributes the load over enough cells to keep the working deflection within the limit, and it is a five-minute fix rather than a specification change.<\/p>\n<p>This approach also keeps the stock list short. Two grades on a site are easy to manage, whereas a different panel in every area is not, and mixed grades on the same route make it impossible to know what is underfoot.<\/p>\n<div style=\"overflow-x:auto;margin:22px 0\">\n<table style=\"border-collapse:collapse;width:100%;font-size:15px\">\n<thead>\n<tr>\n<th scope=\"col\" style=\"border:1px solid #ccd9dc;padding:10px;text-align:left;background:#f4f8f9\">Specification question<\/th>\n<th scope=\"col\" style=\"border:1px solid #ccd9dc;padding:10px;text-align:left;background:#f4f8f9\">Short answer<\/th>\n<th scope=\"col\" style=\"border:1px solid #ccd9dc;padding:10px;text-align:left;background:#f4f8f9\">Evidence to request<\/th>\n<th scope=\"col\" style=\"border:1px solid #ccd9dc;padding:10px;text-align:left;background:#f4f8f9\">In this guide<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border:1px solid #ccd9dc;padding:10px;vertical-align:top\">How to work out the load your protection has to carry?<\/td>\n<td style=\"border:1px solid #ccd9dc;padding:10px;vertical-align:top\">Start by listing the heaviest thing that will cross the protected area and the heaviest thing &#8230;<\/td>\n<td style=\"border:1px solid #ccd9dc;padding:10px;vertical-align:top\">Two different load types appear on almost every site.

A suspended floor deflects under load, and it deflects further as the span increases and as the load is applied away from a support.<\/p>\n<p>This changes the calculation. The panel has to be stiff enough that the deflection it adds does not push the floor beyond its serviceability limit, and the relevant input is the flexural stiffness of the panel rather than only its compressive capacity.<\/p>\n<p>On a spanning floor, the deflection of the finished surface should be confirmed with the structural engineer, and the panel should be specified against a stated working deflection. Panels that are laid loose rather than taped or fixed also reduce the risk, because the panel is then free to settle rather than transmitting movement into the finish.<\/p>\n<h2 id=\"sec-5\">Why the substrate condition matters more than the panel<\/h2>\n<p>A panel laid on an uneven, dusty or damp floor will behave differently from the same panel laid on a prepared one, and no amount of panel specification fixes the substrate.<\/p>\n<p>Dust and debris under a panel are the most common cause of scratching. A single particle of grit trapped between the board and a hardwood floor is enough to produce a visible scratch when a trolley crosses it, and the damage cannot be undone without resanding or refinishing.<\/p>\n<p>An uneven floor introduces high spots that concentrate the load onto individual core cells, which is precisely the failure mode the panel was chosen to avoid. Sharp edges in a screed can also cut into the facing and puncture the board.<\/p>\n<p>A damp floor is a separate issue, because a sealed panel traps the moisture and can cause the screed or the adhesive beneath to deteriorate. Preparing the substrate means sweeping, checking for sharp edges, confirming dryness and, where the panel needs to sit for a long period, laying a breathable separation layer.<\/p>\n<h2 id=\"sec-6\">What panel thickness tolerates in terms of load<\/h2>\n<p>Panel thickness sets how much load the core can carry before it crushes, and because the relationship is roughly linear, the useful move is to work in internal load capacity rather than thickness labels.<\/p>\n<p>Increasing core height increases the section modulus of the core wall, so the compressive strength available at the face rises faster than the thickness figure suggests. A thicker board is meaningfully stronger, but the relationship is not a simple doubling of strength for a doubling of thickness.<\/p>\n<p>Published internal load capacity for <a href=\"https:\/\/www.mingplastics.com\/fr\/produit\/temporary-floor-protection-board-with-felt-backed-pp-honeycomb-panel-for-renovat\/\">honeycomb panel<\/a>s is normally given in kilograms per square metre at a defined deflection, and the deflection limit is part of the number. A figure quoted without its deflection is not comparable with another figure, which is a frequent source of confusion in specifications.<\/p>\n<p>The practical method is to establish the heaviest repeated load on the site, convert it to an equivalent uniformly distributed load, and compare that against the capacity of the chosen board at the deflection limit that the floor finish can tolerate. The tolerance of the finish is often the binding constraint, not the strength of the board.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3 id=\"faq-1\">Why does a small contact area cause more damage?<\/h3>\n<p>Start by listing the heaviest thing that will cross the protected area and the heaviest thing that will stand on it, then convert those into an equivalent uniform load.
