Good Heat Resistance Prepainted Steel Coil Not Easy To Change Color​

The general commercially available color-coated rolls are now made of cold-rolled substrates, hot-galvanized substrates, zinc-plated substrates, aluminum-zinc plated substrates, etc. In addition, the galvanized steel strip is used as the substrate of the color-coated steel strip. In addition to protecting the zinc layer, the organic coating of the zinc layer also has the function of covering or protecting the steel strip from rust, which is about 1.5 times longer than the galvanized steel strip.

Features of color coated roll

1. Color-coated coils have good durability, and their corrosion resistance is longer than that of galvanized steel sheets.
2. Color-coated coils have good heat resistance, and are less likely to change color at high temperatures than galvanized steel sheets; they have good welding performance.
3. It has good heat reflectivity; the color-coated coil has the processing performance and spraying performance similar to that of galvanized steel sheet.
4. Color-coated rolls have good performance-price ratio, durable performance and very competitive price. Therefore, whether it is architectural designers, engineers or manufacturers, galvanized steel sheets have been widely used in industrial buildings, steel structures and civil facilities, such as garage doors, gutters and roofs.
