U Channel steel Arch Support or U Shaped Steel Bracket is a cross-section like the English letter "U" of steel for underground mining and tunnel roof support. U-shaped steel bracket is mainly used in mine tunnel, mine tunnel secondary purpose supporting, as well as the support of the mountains tunnel support and others.
However, due to the understanding of the performance and requirements of the U-shaped steel arch support are inconsistent, therefore the U-section of the cross-section shape, geometric parameters and materials are not the same in different countries. China's U-shaped steel production models are 18U, 25U, 29U, 36U, 40U .
1. withstand pressure
2. supporting a long time
3. easy to install
4. not easy deformation characteristics
