1. The section of C-section steel is economical and saves materials. The section shape can be designed according to the needs when working, and the effective structure is reasonable. The section coefficient per unit weight is higher than that of hot-rolled section steel. Cold-formed steel used in construction contains 38-50% less metal than hot-rolled steel, and used in agricultural machinery and vehicles can save 15-60% of metal. Convenient construction, reduce the comprehensive cost. 2. The variety of C-type steel is more diversified. When running, the general hot rolling method is difficult to produce a variety of steel with uniform wall thickness, complex cross-section shape and a variety of materials of cold formed steel. The surface of the product is smooth, the appearance is good, the size is good, the length can also be adjusted flexibly according to the need, can be supplied with a square or times, and improve the utilization rate of materials. C-shaped steel mainly refers to steel plate or steel, in the cold state bending of various cross-section shapes of finished steel, C-shaped steel is also known as cold-formed profiles or cold-formed steel, is an economical cross-section of light film steel. C-shaped steel is the main material for making light steel structure. It has a very thin, reasonably shaped, complex cross-section that cannot be produced by heat. Compared with hot-rolled steel, in the same section area, the rotation radius is increased by 50% to 60%, and the section moment of inertia is increased by 0.5% to 3.0 times, so the material strength can be used more rationally. C-type steel is one of a variety of steel varieties, in operation, under normal temperature conditions effectively longitudinal array of a group of rolls, gradually deformed to meet the requirements of the use of the shape and size, and then determine the size, cut into the corresponding length. This product is cold-formed steel. Of course, C-shaped steel can also be obtained by pressing, bending or drawing deformation methods. C-type steel is mainly hot-rolled or cold-rolled strip steel as billet, bending in the process of forming a variety of cross-section geometry of steel. The section of C-section steel is very economical and reasonable, and materials can be saved when used. The section shape of C-section steel can be designed according to needs, and the scale is reasonable to a certain extent. The section coefficient per unit weight is higher than that of hot-rolled section steel, which can reduce the weight of parts and save materials under the same load. C-shaped steel is used in construction for 38-50% less metal than hot-rolled steel, and for agricultural machinery and vehicles can save 15-60% metal. Convenient construction, reduce the comprehensive cost. There are many kinds of C-shaped steel supply cold steel, in the production process, it is generally possible to use the ordinary hot rolling method is difficult to produce thick wall uniform, complex cross-section of C-shaped steel cold steel and various materials of cold steel.
Q690 High strength C-shaped steel
Q690 low alloy high strength C section steel its strength, toughness, plasticity, corrosion resistance and weather resistance are stronger than the general carbon material, generally used for higher stress requirements, or higher plastic requirements, or relatively special environment work, such as low temperature, high corrosion environment. With the advantages of adjustable size and high compressive strength, it is widely used in automobile, railway vehicle, building doors and Windows, transportation, shelves, electrical cabinets, highway guardrawers, construction steel structure, containers, steel formwork scaffolding, solar support shipbuilding, Bridges, transmission towers, steel sheet piles, cable tray, agricultural machinery, furniture, storage, guide rail, keel steel, vegetable greenhouses, pipeline support , municipal construction and other fields. Q460C/Q460D can be used in buildings below -20 degrees Celsius all year round, with high safety factor and wide application range
