(9) Construction China light duty shelves Compared with hot-rolled steel, the radius of gyration can be increased by 50-60% and the moment of inertia of the section can be increased by 0. The application of cold-formed steel in China’s railway wagons will be more and more. Since the middle beam is welded with a hot-rolled steel, it exists.(2) Railway vehicles: Most of the passenger cars and freight vehicles use special shaped cold-formed steel, for example, cold-formed middle beams instead of hot-rolled middle beams.(3) Small cold-formed steel: the product thickness is . Another example: Qiqi Group developed cold-formed steel for end wall transverse belts and hat-shaped steel side columns in 198.The middle beams used in the chassis of the car, the caravan, and the tanker are all hot-rolled steel-welded welded structures.
Our products have broad markets in Southeast Asia, India, North and South America, Western Asia, Russia, and Australia. In the high-voltage long-distance transmission tower, high-strength and anti-corrosion structural steel pipes have been tried in various places. We guarantee first-rate after-sale service and product quality.5-. The production of cold-formed steel can meet the different requirements of various industries and produce various special cold-formed steels.(2) Closed cold-formed steel is a cold-formed steel with a closed section of welded shape, which is round, square, rectangular and shaped according to its shape.(1) Cold-formed steel for automobile manufacturing; small passenger cars, mostly with irregular-shaped open-shaped steel, such as windows, rain gutters, seat machine pulleys. The cold-formed middle beam developed by WISCO uses hot-rolled coiled sheets as raw materials, and the integral middle beam is obtained by continuous molding.(8) Agricultural machinery: cold-formed steel for tractors, plows, hoes, and harvesters, and cold-formed steel for agricultural vehicle beams. Establishing an abiding friendship with any customers interested in roll forming machines is our goal. Cold-formed steel is classified according to the application.(10) Furniture: Stools, chairs, cabinets, beds, etc. The utility model has the advantages of large weight, high welding quality requirement (need to be non-destructive testing), and high comprehensive cost.(6)Construction machinery: crane lifting arm, support arm, cold-formed steel for tower crane frame.
Large-scale cold-formed steel: the thickness of the product is 6-16mm, and the product has a width of 600-2000mm. Cold-formed steel is classified according to size specifications and is divided into four types: large, medium, small and wide in terms of product thickness and expansion width. are special cold-formed steel. The main items can be listed below.0 times in the same cross-sectional area, so that the material strength can be used reasonably; That is to say, compared with the traditional steel structures made of I-beam, channel steel, angle steel, and steel plate, it can save about 30 to 50% of steel.Classification and application
