The color coated plate rolling has the advantages of both organic polymers and steel plates. The great stainability, moldability, reat corrosion resistance and decoration is like the organic polymers. Besides, color coated plate has high strength and it is workable.
Frankly, it is easy to cut, curve, deep-draw and solder. The organic coated steel products are practical, decorative, workable and durable. There are more than 600 types of color coated plate, but it has no unified sorting technique. Every factory has their unique equipment and craft, so it is very hard to get a divisive standard. Now, it is divisived according to its custom.
(1) According to its placodes. They are cold rolled sheets, hot zinc coated steels, electric galvanized sheets, alloying plates, galvanized aluminum plates, chrome plates, and aluminum plates.
(2) According to its crafts. They are coating, spraying, powdering, coating film method and printing. There are many crafts, such as one coat-one bake, two coat-two bake, three coat-three bake, and four coat-four bake, according to the coatings. The coated steel has different types, such as wood board, marble, leather grain, cement mortar grain, due to the printing craft.
(3) According to the coating types. They are vynitop, polyester coating steel plates, acrylic coating plates, fluorocarbon coating plates, and polyester coating silicon steel plates, etc.
(4) According to the coating’s performances. They are high weather resistance and high temperature resistant coating plate coating plates, self-extinguishing coating plates, non-stick coating snow boards, fingerprint resistant coating plates and self-lubricating coating plates.
(5) According to the special coatings and uses. They are zinc-rich coatings, organic coating steels, and some special laminated composite panels.
The haze is very heavy in Beijing and Tianjin, and 60% has halted production. Handan steel group is asked to reduce output 50% between 15th to 22th December. The Handan steel group has executed the policy. Except for natural gas factory, other fire coal factories has halted production.
Although only few blast furnace enterprise halt production, most welding furnace has halt and reduce production. If the weather quality is not improved, the halt production policy will not stop. And the output of blast furnace will reduce soon.
The trend of the billet market is negative, which brings high pressure for the steel spot market. Besides, the high level of resource makes the trading volume not up to the mark. The suppliers is still dominated by shipping and the callback of the spot price is naturally. The haze pollution is very heavy in the North China, and the iron factories will halt production due to protect the environment.
So, the short supply face a great pressure. But the price increases substantially, and the cost pressure is very great. It estimates that the price will decline tomorrow, but it will increase late.
