Galvanized sheet is the metal product for the making of which cold-rolled (less often - etched hot-rolled) rolled or sheet steel are used. Protective zinc layer is applied to the steel base. Galvanizing provides not only barrier (on the type of paints and lacquers), but also electrochemical protection of rolled steel against the corrosion. Depending on chemical composition and application method, protective layer is able to have different thickness, appearance, operational characteristics.

The most widespread field of use of galvanized sheet is manufacturing corrugated board, metal products used, depending on the grade, as roofing material, for construction of fences, wall facing, in the manufacturing multilayer (“sandwich”) panels. Flat sheets are in demand for the manufacturing additional elements of roofs constructs - ridges, joints, gutters and pipes.
