U-shaped steel is a steel with a cross-section like the English letter “U”, the new standard was issued in 2008 and was implemented on April 1, 2009, National Recommendation: GB/T 4697-2008.

U-shaped steel bracket main feature: high pressure, long support time, easy to install and not easy to deform. Main use: mainly used for mine roadway, secondary support of mine roadway, support support of mountain tunnel, etc. As the main type of steel for manufacturing roadway shrinkable metal brackets, u-shaped steel is used at home and abroad. However, due to the different understanding of the performance and requirements of U-shaped steel itself, the cross-sectional shaped, geometric parameters and materials of U-shaped steels vary from country to country. The u-shaped steel models produced in China mainly include 18U, 25U, 29U and 36U. The first two are products from the 60s, which are waist positioning; the latter two are products of the 80s, which are ear positioning. U18 is rarely produced due to its low carrying capacity, in addition to the above four models of U-shaped steel in GB/T 4697-2008, a new 40U model is added.
