Benlog PREPAINTED 55% AI-Zn ALLOY-COATED STEEL COILS / GALVANIZED STEEL COILS
55% Al-Zn alloy-coated steel sheets and galvanized steel sheets have excellent corrosion resistance. However, to improve their dull and changeless surface, color coating and baking on the surface of 55% Al-Zn alloy-coated steel sheets and galvanized steel sheets produce beautiful and high corrosion resistant prepainted steel sheets.
Steel Specification:
Thickness: 0.2-3.0mm
Width: 600-1500mm

Tolerance for thickness,width,flatness and so on conform to the requirements of JIS G3302 or ASTM A653M/924M
Coil ID can be either 508mm or 610mm, maximum coil OD is 2000mm
The speicfication of ASTM Such as A653m,A924 M and so on have been updated to the latest revisions
Characteristics
1.Many colors are available to match the environment and attach value to the appearance.
2.Superior resistance against environment :Heat resistance, corrosion resistance, humidity resistance, weather proof etc.
3.Formability, impact resistance, and acid/alkali resistance, superior workability and chemical resistance are the major reasons for the popularity of prepainted 55% Al-Zn alloy-coated and galvanized steel sheets.
4.Color according to RAL Color system or customize.
