(9) Construction China light duty shelves industry: steel structure (beam, column) maintenance structure, roofing, wall, door and window, cold-formed steel for decoration.(7) Electrical equipment manufacturing industry: electrical cabinets, cold-formed steel for cable trays. In 1993, cold-formed steel for upper side beams of rectangular tubes with sharp corners was developed. Cold-formed steel is an economical thin-section thin-walled steel, also known as steel-refrigerated curved or cold-formed profiles. It has a variety of extremely thin, well-shaped and complex sections that cannot be produced by hot rolling..BOSJ coil former manufacturers has won a worldwide reputation in this field.
They are welded by two hot-rolled sheets of steel with a height of 310.(2) Medium-sized cold-formed steel: the product thickness is 3-6mm, and the product expansion width is 200-600mm. Therefore, the railway department hopes to develop a high-efficiency cold-formed steel with integral shape, lightweight, high strength and good rigidity instead of hot-rolled steel.(1) Universal open-formed cold-formed steel with equilateral and unequal angles, inner and outer bead angles, equilateral and unequal channel steel, inner or outer bead channel, Z-beam, coil Side Z-shaped steel, special shaped open-section steel, etc.5-4mm, and the product expansion width is 30-200mm. Sincerely, we invite you to pay a visit to our company.5-4mm, and the product has a width of 700-1600mm.
The material is cold-formed steel 09CuPTiRE-A The yield strength is 295 MPa.. Cold-formed steels are classified according to their shape and can be divided into open and closed.(3) Elevator: hollow guide rail for the elevator, structural frame for the automatic elevator and cold-formed steel for other special-shaped members(4) Shelf: Cold-formed steel for small supermarket shelves and large warehouse-style supermarket shelves.(5) Transmission tower: Focus on the study of replacing the traditional hot-rolled angle steel with cold-formed steel to improve the overall performance of the tower and reduce costs. The triangular tower structure made of cold-formed steel for the communication tower is also under development. Cold-formed steel is the main material for making lightweight steel structures.
Different industries have different requirements for cold-formed steel. Open for a long time. Most of the buses use closed rectangular steel, and most of the freight cars use open-cold steel; special vehicles such as fire trucks, engineering vehicles mostly use rectangular and shaped cold-formed steel. Cold-formed steel refers to a finished steel product of various cross-sectional shapes bent by a steel plate or a strip in a cold state.
