PPGI Corrugated Sheets has been used extensively by the construction industry throughout the World for nearly two centuries. Because of its excellent corrosion resistances, it has become the preferred material for a wide range of construction uses, particularly roofing and walling. PPGI Corrugated Sheets is a unique building material. It combines the strength of steel with the excellent corrosion protection of zinc/aluminum alloy coatings. It can be punched, roll-formed and joined in to a limitless number of structural and decorative building products.
