Steel panel material introduction: Cold rolling is made of hot rolled coil, and is rolled at a normal temperature below recrystallization temperature. A cold rolled steel sheet is a steel sheet produced by a cold rolling process, and it is referred to as a cold plate. The thickness of the cold-rolled sheet is generally between 0.1 and 8.0 mm, but the thickness of the cold-rolled steel sheet produced by most factories is 4.5 mm or less. The thickness and width of the cold-rolled sheet are determined according to the equipment capacity and market demand of different factory.
Cold rolling is a steel sheet which is further rolled to a target thickness at room temperature under a recrystallization temperature. Compared with hot-rolled steel sheets, cold-rolled steel sheets are more precise in thickness and have a smoother and more beautiful surface.

The Advantages of Steel Panel

Production Advantages:

2.Good flatness;
3.Easy to installation
4.Fire proof;

Our Advantages:

1.We have higher requirements on the quality details of our products, such as product size, the shape, the anti-static performance and so on ;
2.The Steel panel is made of bent steel plates with a total of 8 flanges. The strength is better. The surface is a layer of spray paint. The color usually accord with European standard 9002, 9010 or customized requirements, which is usually only for ceiling systems. Since the product itself is formed by bending a steel plate, so the fire resistance is good and the burning grade is grade A. However, since the thickness of the steel sheet of the product is relatively thin, the transfer of temperature is fast, therefore, the heat insulating performance is poor. It is used as ceiling on the FFU keel frame widely used in clean rooms in China.
3.We have been worked on cleanroom industry for 15 years and our company has many professional experts. So we can offer cleanroom solutions or design plan.
