PPGI PPGL Dx51d SGCC Coated Steel Plate ral Prepainted Galvanized Roofing Sheet for Building Material
RoofingSheet
is a plain carbon steel sheet coated in a galvanizing process that applies a barrier of zinc to insulate it from the elements. Most of the
corrugated roofing and siding products seen today and for many years past are made with a galvanized finish. It is most commonly used for commercial, agricultural, and industrial purposes, however, it is now also being recognized as an excellent form of residential roofing.
