3. PVC and TPO These thermoplastic roofing membranes are commonly used in flat roofing applications. PVC (polyvinyl chloride) and TPO (thermoplastic polyolefin) are known for their durability, energy efficiency, and resistance to UV rays and chemicals, making them ideal for commercial buildings and warehouses.

Hot-dip galvanizing entails immersing the prepared metal in molten zinc, resulting in a thick, durable coating that provides excellent corrosion resistance. On the other hand, electro-galvanizing uses an electric current to bond the zinc to the surface, producing a thinner but more uniform layer. Once the galvanization is complete, the windows undergo further processes such as painting or powder-coating to enhance their aesthetics while providing an extra layer of protection against weather elements.

2. Adhesion Properties The roughness of galvanized iron can significantly influence the adhesion of coatings and paints. A rougher surface might provide better mechanical bonding for additional coatings, while a smoother surface may require different types of preparations for optimal adhesion. Suppliers must be familiar with these properties to advise their clients effectively.
