| 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.
| 
|
|
|
| CHARACTERISTICS |
- Many colors are available to match the environment and attach value to the appearance.
- Superior resistance against environment : Heat resistance, corrosion resistance, humidity resistance, weather proof, etc.
- 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.
