Galvanised sheet metal is the state of the metal coated with "Zinc" in order to prevent corrosion of the metal. Galvanised flat steels are produced as a result of coating both surfaces of cold rolled metal with zinc layer by hot dipping process. The places where galvanised sheets are used are environments where there is a high risk of corrosion and exposed to adverse effects such as moisture.

Galvanised sheet metal is used in roof and facade cladding, trapezoidal sheet, sandwich panel and under-concrete trapezoid in the construction sector by giving appropriate form.
