Development Trend of Improvement of Colored Steel Plate in Rolling Coating Production Settings of Colored Steel Plate

Now the application of color steel plate is increasing, mainly because color steel plate has outstanding functions. Today we mainly understand the outstanding features of color steel plate in detail.

1. Colored steel sheet is beautiful in appearance: the clear lines of colored steel sheet can meet the needs of any style building, and the spraying line of automatic gun achieves satisfactory results.

2. Colored steel plate is light in weight: less than 14KG per square metre can fully reduce the structural load and reduce the structural cost.

3. Fire prevention: The surface material and thermal insulation material of the color composite sandwich panel are non-combustible materials, which can fully meet the requirements of fire protection specifications.

4. High Strength: Using high strength steel plate as the base material (tensile strength 5600KG/CM), coupled with the most advanced design and rolling forming, it has excellent structural characteristics.

5. Insulation and insulation: The commonly used insulation materials of the composite board are rock wool, glass fibre wool, polyethylene, polyurethane, etc., with low thermal conductivity and good thermal insulation effect.

6. Durability of coloured steel plate: Various studies have shown that, as well as the extensive use abroad for more than 40 years, the shelf life of coloured steel plate treated with special coating is 10-15 years, and after spraying anticorrosive coatings every 10 years, the life of the plate can reach more than 35 years.

7. Coloured steel plate installation is relatively fast: the color steel plate is a composite plate, light weight, splicing installation and arbitrary cutting characteristics, determine its installation is simple, can greatly improve efficiency and save time.

Development Prospect of Improvement of Colored Steel Plate

1. The color steel plate improves the pretreatment process and the pretreatment liquid, the equipment quantity is small, the low cost becomes the mainstream process, unceasingly improves the stability, the corrosion resistance, the environmental protection performance of the pretreatment liquid.

2. The equipment of color steel plate unit is more perfect. For example, new welding machines, new roll coating machines, improved curing furnace, advanced automation instruments and so on.

3. The color steel plate adopts high-quality base plate, which requires higher and higher accuracy of the surface, shape and size of the base plate. For outdoor use, such as small galvanized flat hot galvanized steel coil, clean air supply system galvanized flat hot galvanized steel coil, galvanized alloy hot galvanized coil rising in time; for indoor use, such as galvanized steel coil, coated cold-rolled sheet and aluminium coil.

4. Because of the low cost of cold embossing compared with hot embossing, the color steel plate has the characteristics of beautiful appearance, stereoscopic feeling and high strength, so the cold embossing technology has become the development trend.

5. Colored steel sheet pays attention to the diversification, functionalization and high-grade of products, such as deep drawing color coated sheet, "pomelo peel" color coated sheet, anti-static color coated sheet, pollution-resistant color coated sheet, high heat-absorbing color coated sheet, etc.

6. Colored steel sheet pays attention to the development of new coatings, and improves general polyester, polyvinylidene fluoride (PVDF) and plastic sol to obtain super color repeatability, anti-ultraviolet, anti-sulfur dioxide, and improve corrosion resistance; and develops anti-pollution, heat absorption and other functional coatings.
