Coated steel cladding comes as profiled steel sheets or composite panels, which are used to clad walls and roofs. It is used for cladding a large proportion of industrial, warehouse and out-of-town retail units. The challenge for coated steel cladding makers is to make a product that both resists corrosion and looks good. To achieve this, coated steel cladding is a composite laminated product comprising: 1. Steel sheet 0.4-2 mm thick, which on its own would rapidly rust in the UK climate 2. A corrosion protection layer; zinc or zinc-aluminium alloy applied by a hot-dip process 3. A paint finish: an organic coating to provide an attractive finish, usually applied by a roller, typically based on polyvinyl-chloride (PVC or plastisol), polyvinylidene-fluoride (PVDF or FVF2), polyester or polyurethane formulations.
