1. Color Coated Galvalume Steel Coil introduction:
Color Coated Galvalume Steel Coil is typically with a hot dip aluzinc coated steel substrate. Prepainted
aluzinc steel coil 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 Coated Galvalume 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. Color Coated Galvalume Steel Coil main usage:
Prepainted galvalume steel coil is often used as building materials(ceiling, metal roof tile) machinery
parts(electrically controlled cabinets, road maintain board, etc, so galvalume color coated coil is mainly
used in advertising industry, construction, household appliances industry, electrical industry, furniture
industry and transportation.

5.Color Coated Galvalume Steel Coil features :
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.
