Hot Rolled Q235 Material For 18kg U-shaped Steel Mine Roadway Support Has High Deformation Resistance And Strength. The

Main features: high pressure resistance, long support time, easy installation and not easily deformed.

Main use: Mainly used for supporting mine tunnels, secondary support of mine tunnels, and support of mountain tunnels.

As the main type of steel used to manufacture retractable metal supports for tunnels, U-shaped steel is widely used both domestically and internationally.

However, due to inconsistent understanding of the performance and requirements of U-shaped steel itself, the cross-sectional shape, geometric parameters, and materials of U-shaped steel vary from country to country, mainly including four types: 18U, 25U, 29U, and 36U
