29U steel bracket, steel shed, W steel strip, π - shaped steel
A U-shaped steel bracket is a type of steel with a cross-sectional shape resembling the English letter 'U'. The cross-sectional shape, geometric parameters, and materials of U-shaped steel produced by different countries vary. The 29U steel bracket has the advantages of high initial support force, strong support strength, easy installation, and low deformation. Therefore, it is commonly used to manufacture retractable metal brackets for mine tunnels, secondary support for mine tunnels, and support for mountain tunnels.
