Rely on its excellent processibility, the color coated steel coil has been widely applied in some areas. Such as building, home appliances, automobile and son on. Its excellent processibility can largely depends on the size of the prepainted steel adhesive force….
Galvalume Steel Sheet Texture The three important elements of galvalume steel sheet are zinc, aluminium and aluminum-zinc alloy material. Zinc is generally expressed in Z, and is the abbreviation of Zinc. In the specification, there always appears Z80, it refers…
Different application environments will need different kinds of ppgi steel coils: When there’s high requirements on forming, users should choose ppgi steel coils of TDC53D、TDC54D series; For components with load requirements, the appropriate structural steel should be selected according to…
There are snow-like spangles on the surface of galvalume sheet metal. And according to the different of steel mill, the spangle size and uniformity will have some difference. With the thickening of the galvalume sheet metal, the size of the spangle…

For different color coated steel coil use environment, using different types color coated steel coil can have more effective prevention to achieve a certain number of service time. For example, the ordinary environment generally use ordinary PE polyester color coated steel…
The difference in the protective atmosphere is mainly manifested in the difference in hydrogen content. Galvanized hydrogen content is generally controlled at 15-30%, while the hydrogen content of galvalume is generally controlled at 25-50%. The controlled temperature when entered the…
The national steel market prices rose narrowed on August 2nd. On the construction steel aspect, the prices rose sharply in nearly two days, the downstream procurement enthusiasm has weakened. Spot high turnover performance is poor, the market’s wait and see…
The T-bend performance reduction is the initial color coated steel coil performance of the metal corrosion under the coating. At this time, there won’t have coating blister or fall off phenomenon if only observe from the surface. But the T-bend performance…
