The Corrugated sheet is formed by the bending of the corrugated plate, and the corrugated plate is usually made by roll forming. The roll pass system has a continuous forming system and a special pass system. At present, the most widely used corrugated sheet forming system is continuous forming system, that is to say, first bend the center wave, then bend the adjacent wave, and finally bend the wave. The advantage of the pass system is that the roller consumption is lowest, and its disadvantage is that the workpiece is prone to bending and twisting. The special pass system is mainly used to produce corrugated plate. At first, the arc wave is pre bent, and then it is formed by upsetting and pressing. This method ensures the metal thinning at each bend angle is lightest. Its disadvantages are high roller consumption and high requirements for forming equipment and materials.

Galvanised steel is mild steel with a coating of zinc The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel Galvanised steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion 

Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.
