Introduction of color steel plate

1. The use of high-quality substrate, the substrate surface, board shape and dimensional accuracy requirements are getting higher and higher, such as outdoor use of small zinc roll flat hot galvanized steel coil, zinc-free hot-dip galvanized steel coil rise Zinc alloy hot rolled coil; indoor use such as galvanized steel coil, film cold rolled sheet and aluminum coil.
2. Improve the pretreatment process and pretreatment liquid, the number of equipment is small, the cost is low Main process, and continuously improve the stability, corrosion resistance and environmental protection performance of pretreatment liquid.
3. Focus on the development of new coatings, the general polyester, polyvinylidene fluoride (PVDF) and plastic sol to improve, to obtain super color reproducibility, anti-ultraviolet, anti-sulfur dioxide, improve corrosion resistance; development of pollution, And other functional coatings.
4. Unit equipment is more perfect. Such as the use of new welding machine, the new roller coating machine, improve the curing furnace, equipped with advanced automated instruments.
5. As cold embossing than the cost of hot embossing, with a beautiful, three-dimensional, high strength, so that cold embossed production technology has become the development trend.
6. Focus on the diversification of products, functional, high-grade, such as deep-color color coated board, "grapefruit skin" color coated board, anti-static color coated board, stained color coated board, high heat-absorbing color coated board
