Strong corrosion resistance: can cope with acid, alkali, salt spray and other corrosive environments, long service life, low maintenance cost High safety: has good insulation performance to avoid electric shock accidents; smooth surface, low friction coefficient, reduce the risk of slipping; also equipped with handrails, covers and other facilities to facilitate workers to get on and off
U-bar has a large load-bearing capacity and can transmit loads in multiple directions. It is suitable for supporting large-span structures. Its cross-sectional shape helps to improve the rigidity and strength of the steel and can withstand large loads and impacts.
Q235B: It is a carbon structural steel, with a chemical composition of carbon (C) ≤ 0.22%, manganese (Mn) ≤ 1.4%, silicon (Si) ≤ 0.35%, etc. Its yield strength is 235MPa, and its tensile strength is between 370-500MPa. It has certain strength and good plasticity, toughness and welding properties. Q355B: It is a low-alloy high-strength structural steel with a high manganese content, a yield strength of ≤ 355Mpa, and a tensile strength of 470-630MPa. Compared with Q235B, Q355B has higher strength, can withstand greater pressure and tension, and has better performance.
SS400 steel channel has the characteristics of good corrosion resistance and high strength, which makes it possible to use thin plates and can play a role in many scenarios that have certain requirements for strength and corrosion resistance. At the same time, it is resistant to heat oxidation and has high strength, can resist fire, is easy to plasticize at room temperature, and does not require surface treatment. It is easy to process, clean and has a high finish, and has good welding performance.
A36 is a common carbon structural steel with moderate strength, which can meet the load-bearing requirements of general structures. A572 Grade50/60/65 is a high-strength low-alloy steel, of which Grade50 has a yield strength of 345MPa. As the grade increases to Grade60 and Grade65, the yield strength is higher and can withstand greater loads.
