Q235 cold rolled carbon steel plate produced by Wanhetong Steel Co., Ltd. is made of high-quality raw materials from China's famous outline factory with yield strength up to 235Mpa, which can better meet the steel requirements of general steel structure and reinforced concrete structure and is widely used in construction
Q235 steel is a carbon structural steel, "Q" represents the yield strength, "235" is its yield strength value, the unit of MPa. According to the national standard "GB/T 700-2006 carbon structural steel" provisions, Q235 steel is divided into A, B, C, D four grades,
Q235A: suitable for bearing static load of the structure
Q235B: Construction for critical welding
Q235D: Suitable for use under strong impact force and vibration load, especially at low temperature
Q235 cold rolled carbon steel plate can still maintain stable mechanical properties after welding, the thickness is generally 0.1-8.0mm, most of the factory production of cold rolled steel plate thickness of 4.5mm and below, the steel plate size is accurate surface bright quality, can be directly processed into finished products, widely used
① Automobile manufacturing: body structure, chassis, interior
② Home appliances: refrigerators, washing machines, air conditioners and other shell and internal structural parts
Construction and machinery manufacturing: steel structures, Bridges, components of large buildings, mechanical parts, etc
