WHAT IS COLD ROLLED STEEL PROFILE?
Cold-formed steel sheet piles are a kind of steel sheet piles, which play a great role in construction and can solve many problems when used properly. Cold-formed steel sheet piles are steel strips or a continuous cold-bending deformation to form Z-shaped, U-shaped or other shapes of different cross-sections, which can be connected to each other through locks.
The origin of cold-formed steel
At the beginning of the twentieth century, with the development of coiled thin strip production, cold-formed steel has been developed. In the past ten years, coatings (galvanized, aluminum), coatings (color and pattern) and coatings and bimetallic cold-formed steels have also been developed abroad. At present, more than ten foreign countries have produced cold-formed steel. Among them, the United States is the first, Japan has developed cold rolled steel profile for sale rapidly, and Switzerland has the best stability.
Such as: in 1983, the Swiss Montanstahl steel profile family group enterprise. Since 1983: began to produce hot-rolled steel, OEM special steel profile for sale and other profiles. Has seven production technologies: hot rolling, cold rolling, cold drawing, laser welding, low impact laser welding, 3D laser product details of cold rolled steel profile and Hybr laser. Montanstahl is officially rated as “Risk Indicator 1” by Dun&Bradstreet/Bisnode (the largest and oldest business credit investigation agency in the United States) and has been named the best company in Switzerland.
In terms of varieties, foreign cold-formed steel varieties have 30,000 to 40,000 varieties and specifications. Including various carbon steel, low alloy high strength steel and stainless steel and other cold rolled steel profile for sale steel grades. The thickness is 0.1–20 mm (generally 3–4 mm for production), and the unfolded width is 20–2000 mm (generally below 50 mm). In addition, it can produce various ultra-thin, ultra-wide and complex-shaped sections that cannot be produced by hot-rolled steel.
Technology of cold-formed steel
Cold-formed steel is generally made of hot-rolled or cold-rolled steel as raw materials. At room temperature, it is processed by drawing, stamping, bending or roll bending forming units to process various thin-walled profiles that are difficult to produce OEM special steel profile for sale by hot rolling. Cold-formed steel has the characteristics of reasonable section, high strength, light weight and high metal utilization rate. It is an economical section steel and is widely used in automobile, aviation, construction and other industries. Cold-formed steel is divided into cold rolled steel profile for sale open-section cold-formed steel, semi-closed cross-section cold-formed steel, and closed-section cold-formed steel. Cold-formed steel is a very efficient manufacturing process, which was mainly developed for small sections. The production of various sizes of product details of cold rolled steel profile by cold bending has higher dimensional accuracy than hot-rolled steel, and its tolerance is small. These tolerances are based on the tolerances of the raw metal (strip steel), generally ± 0.127 mm, and in some cases ± 0.025 mm when the section is small. In addition to high dimensional accuracy, it also has a high surface finish.
Advantages of cold-formed steel
1. It is light in weight and has a large bearing capacity. It can save OEM special steel profile for sale metal 25–35 intestines if it is used to replace hot-rolled steel. If it is used for transportation vehicles, it will reduce its own weight, increase its carrying capacity, and save energy;
2. The forming speed is high, the output is high, the variety is large, and the coating is not damaged, and it can produce various ultra-thin, ultra-wide and complex section steels that cannot be produced by hot rolling;
3. It can cause a large plastic deformation of the steel, thereby improving the yield of the steel;
4. The wall thickness of the cold rolled steel profile for sale profile can be increased by bending to make the whole window stronger. At the same time, a closed thermal insulation cavity is formed by one-time bending. If the product details of cold rolled steel profile thermal insulation material is incorporated, it can produce a very good thermal insulation effect.
XAK cold rolled steel profile introduction
High-speed guardrail groove steel profile is a common special steel profile we could see in the traffic road. This kind of cold rolled special steel profile’s main material could be carbon steel; stainless steel; pre-galvanized sheet. XAK provide OEM service. NEW AOKAI could produce products according to drawing or sample.
The OEM Cold Rolled Steel Profile is XAK’s main business for more than 10 years. The rolling process is much more precise than cold bending and stamping. It is also much cost-saving than laser cutting or wire cutting or washing.
In XAK, the OEM means every process section from the base material to the final packages. Besides the basic shaping process, the vertical family business also makes deep process available, such as cutting, laser cutting, punching and welding. Welcome to send us the drawings with details and requirements marked.
