The production of cold-formed steel in China began in the 1950s. The first specialized roll-type cold-bending unit was commissioned in October 1958. In 1946, the first cold-formed thin-walled steel structure design specification announced by American AISI.
Cold-formed steel is also widely used as a load-bearing structure, retaining structure, and accessories in light steel houses. In the building construction, cold-formed steel can be used as the main load-bearing member such as steel frame, truss, beam, and column. It is also used as the secondary beam, wall frame beam, keel, door and window, roof slab, wall panel, and floor slab. Components and enclosures. In addition, the cold-formed steel-concrete composite structure using cold-formed steel and reinforced concrete to form composite beams, plates, and columns has become a new research direction in the engineering field. Cold-formed thin-walled steel structural members usually have pressed steel plates, purlins, wall beams, and rigid frames.
The C-shaped steel, which is the frame of the mobile homeowner, also determines the price of the cold-formed steel. The frame is welded by steel pipes, H-beams, and C-shaped steel. The poor quality of the frame material is not up to standard, the thickness of the steel is smaller than normal, which will affect the firmness of the mobile home, and there are serious safety hazards. Therefore, choosing the right C-steel manufacturer and ensuring quality are the most important.
The market of cold-formed steel is a war without smoke. The competition will become more and more fierce. The manufacturers of cold-formed steels want to have a place in the market. I hope that the first priority is to ensure the quality of our products. The customers want to be durable. The product. At the same time, the use of word-of-mouth publicity by our customers is much better than simply lowering the price.
As an outstanding representative of the new generation of steel cold-formed steel, the use of C-shaped steel is very extensive, otherwise, it will not be so popularized by the application. C-shaped steel which is cold-formed by hot coiling, the thin wall is thick and light, the strength can be said to be very high, and the performance of the cross section is also extremely superior. Compared with the conventional conventional conventional channel steel, it is not only more Environmentally friendly, and at the same strength, C-shaped steel can save 30% of the material, so that the advantages of C-shaped steel naturally emerged.
