1. Color steel coil brief introduction
It is used galvanized steel or the galvalume steel as the base materials, after surface pretreatment, such as chemical degreasing and conversion treatment, next passed to be painted and baked, then we get the final products
2. Color steel coil quality control
Strict procurement process---skillful technical workers---final products inspection (resistance to corrosion, salt spray test, exposure test, machinability, thermal resistance)---standard packing
3. Features of color Steel Coil
1) Excellent corrosion resistance: 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
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: Color steel coil can be used in the various areas
4. Color steel coil end application
It is used in different activity sectors such as construction (roof, wall and ceiling claddings, lighting, radiators etc, ), general industry (office furniture, heating, ventilating, air conditioning), domestic appliances (refrigerators, washing machines, small kitchen appliances, computer casings, VCR & DVD casings, etc. ) packaging

6. Color steel coil coating on production line
Coating is a continuous, automated process for coating metal before fabrication into end products. The steel or aluminum substrate is delivered in coil form from the rolling mills. Color steel coil is positioned at the beginning of the coating line, and in one continuous process, the coil is unwound, pre-cleaned, pre-treated, pre-primed, and prepainted before being recoiled on the other end and packaged for shipment
