1. Color steel roofing sheet introduction
Color steel roofing sheet is produced by direct application of a paint (after applying a treatment and, in most instances, a primer) onto steel sheet in a coil-coating line. Coil-line painting can be used to apply a paint coating directly on uncoated steel sheet or on metallic-coated steel sheet.
2. Color steel roofing sheet main features
1)Color steel roofing sheet protects against corrosion in air and water, and has allowed corrugated metal roofing to become one of the most durable and withstanding roofing materials available.
2)Color steel roofing sheet has features of easy installation, high strength, low in costs, durable and nice appearance.
3. Color steel roofing sheet application scope
Color steel roofing sheet is most commonly used for commercial, agricultural, and industrial purposes, however, it is now also being recognized as an excellent form of residential roofing. Galvanized roofing sheet is also known used as sinusoidal, corrugated iron or wriggly tin.
4. Color steel roofing sheet raw materials
(1)Hot dipped galvanized steel sheet
(2)Pre galvanized steel sheet
(3)Galvalume steel sheet
(4)Pre painted galvalume steel sheet
5. Color steel roofing sheet technical processing
Hot rolled steel coil -->Cold rolled- >hot dipped galvanized/ galvalume/painted- > corrugated-->packing
6. Color steel roofing sheet new high technology
Color steel roofing sheet is produced on high technology coil coating lines under rigid quality controls, this product has a painted finish that is uniform in color, gloss, texture and thickness, with excellent paint adhesion and durability. Today's combinations of metallic coatings and paint systems provide corrosion resistance and formability at levels considered impossible only a few years ago. Steel sheet can be readily rollformed, bent, and stamped without degradation in the quality of the paint.
