1. Prepainted aluzinc steel roll introduction
It 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. Prepainted aluzinc steel roll 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. Prepainted aluzinc steel roll main usage
It is often used as building materials(ceiling, metal roof tile) machinery parts(electrically controlled
cabinets,road maintain board, so galvalume color coated coil is mainly used in advertising industry, construction,
household appliances industry, electrical industry, furniture industry and transportation

5. Prepainted aluzinc steel roll features
1) Excellent corrosion resistance: The zinc layer provides a good protection of steel sheet
2) High heat resistance: Reflective surface of the material aids in efficiently reflecting the sunlight
away and in turn reducing the amount of heat transmitted
3) Aesthetics: Available in plethora of patterns and multiple sizes that given by customers
4) Versatility: can be used in the various areas
