U-shaped steel is named because its cross section is very similar to the English letter "U".
U-shaped steel is also called mine support steel, which is mainly used to make U-shaped steel brackets or arched steel sheds, which are used in coal mine tunnels and roadway support.
U-shaped steel can be divided into: 25U-shaped steel, 29U-shaped steel, 36U-shaped steel, and 40U-shaped steel according to the weight of the meter. U-shaped steel can be divided into different lengths: 8-meter-long U-shaped steel, 9-meter-long U-shaped steel, 10-meter-long U-shaped steel, 11-meter-long U-shaped steel, and 12-meter-long U-shaped steel.
