Roofing Sheet PPGI DX51 ZINC Coated Cold Q235 Hot Dipped Galvanized Steel Coil For Construction
The use of galvanized/galvannealed products in the automotive industry is growing over the years because of the requirements for improved corrosion resistance and paint adherence. Most automotive manufacturers use galvanized products for both exterior and interior parts, enabling them to guarantee up to life-time warranty against corrosion. Hot dip galvanized steels are used for various components of the car body. Structural hot dip galvanized/galvannealed steels are used for a wide range of applications in the building sector. Depending on the atmospheric conditions and the desired corrosion resistance, the steels which need different coating thicknesses are mainly used in cladding, roofs, doors, fences, profiling and components for agricultural machinery applications.
