Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates ASTM A514 QT steel plate for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.
Our company will accept the product quality objection registration record, pass it to the ASTM A514 QT steel plate production unit and relevant departments, and timely coordinate the supervision of product ASTM A514 QT steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
