  Advantages of Our Prepainted Galvanized Steel Coil: 1) Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted Galvanizeed Steel Sheet. 2) High heat resistance: The reflective surface of the material aids in efficiently reflecting the sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity converts into energy savings. 3) Aesthetics: Pre-Painted Galvanized steel sheet is available in plethora of patterns and multiple sizes as per the requirements that given by our customers. 4) Versatility: can be used in the various areas.     Applications of Prepainted Galvanized Steel Coil:   1) Buildings and constructions: roofing, ceilings, gutters, venting lines, indoor decorations, window frames, etc. 2) Electrical appliances: computer shells, washing machines, refrigerators, dehumidifiers, video recorders, water heaters, etc. 3) Agricultural equipments: troughs, feeding tools, agricultural driers, irrigation channels, etc. 4) Vehicle parts: back-seat plates of buses and trucks, conveying systems, oil tanks, etc.     Coating Chief Feature
