Why new material roofing sheet has superior anti-corrosion performance?

Both sides of the substrate are laminated by a polymer film through 200 high temperature pressing,and are completely fused on the surface of the substrate. Even in a strong acid and alkali environment the substrate surface material can protect the substrate very well.

The two samples were placed in the same beaker and soaked for 36 hours at the same time. Alene both sides of the board remain intact. And only a small part of the edge is corroded. The soaked part of the color steel plate has been completely corroded and dissolved.

The structure is airtight, not easy to condense water, and the surface is smooth and easy to clean.There is no need to worry about the risks and hidden dangers of animal nesting and mildew.
