PPGL Coil or Galvalume Pre-painted Coil is an innovative product by combining the strength of steel with the ability of anti-corrosion coating.It is short for pre-painted galvalume steel coil, which uses aluminum-galvanized sheet as the base metal.This material is highly resistant to corrosion and high temperatures up to 315 degrees.PPGL coils are used in a variety of applications such as roofing & cladding, doors & windows, lighting, vehicle manufacturing, furniture, home appliances and shipbuilding industries.1. Corrosion Resistance PPGL steel is uniformly treated with paint to ensure the material has a strong bond to resist corrosion and increase long term durability.2. Heat Resistance Prepainted galvalume steel has great heat reflectivity, which can withstand a high temperature of 315 degrees.3. Beautiful Appearance PPGL steel is more pleasing, aesthetically pleasing, and provides significantly better performance than PPGI steel.
