High-corrosion roofing tiles

High-corrosion roofing tiles (also called Large Pit tiles) are a type of synthetic resin roofing tile with large waves and high wave pitch (mainly PVC/ASA composite). They are formed by extrusion pressing and are different from ordinary small-corrosion roofing tiles. They have larger wave height and wave pitch (common wave height around 40mm and wave pitch 250mm), resulting in faster drainage and higher strength.
