In offices, metal wall panels are attached to walls to improve an area's appearance. In industrial settings, they can be used to protect walls from flying sparks or debris, which could threaten the integrity of a building. In laboratories, metal wall panels are widely used as backsplash plates; they cover walls near sinks or other areas prone to spills with easily-cleanable surfaces. In some cases, contaminant or corrosion-resistant metals can be used, decreasing the risk to laboratory workers and improving conditions for conducting experiments. Metal wall panels can be made of aluminum, bronze, stainless steel, copper, zinc and many other metals, but steel is the most common material. Metal wall panels can be flat, corrugated, textured or smooth and are generally inexpensive to purchase and install. The possibilities for panel design are limited only to a given customer's budget and creativity.Wall panels can be designed and processed in many different ways; because the desired surface texture of one metal wall panel can differ from one design to another, a diversity of panel production methods is required to allow for the range of products customers desire. Roll forming is among the simplest methods for creating wall paneling. Some roll formers can even shape metals that have already been cured, finished or otherwise treated without damaging or changing the qualities of the surface. The process begins with a stock of metal that is fed into a set of rollers. The rollers are positioned in a way that allows them to tightly grip the contours of the metal. The next set of rollers in the sequence, which are positioned no farther than a few inches away from the first rollers, are configured in a slightly different way, one step closer to the final shape the metal will take. Each subsequent roller is positioned in a slightly different way than the last. By the time the metal reaches the last rollers, it has taken its final shape and is ready to be cut and prepared for shipment.
