U-shaped steel arch support (full name: hot-rolled U-shaped steel for mine roadway support) U-shaped steel is a kind of steel whose cross-section resembles the English letter "U", and sometimes the st

Compared with other rigid brackets, it has retractability and stable and reliable bearing capacity, adapts to the load and deformation of soft surrounding rock, high section utilization rate, convenie

We have also introduced the knowledge of U-shaped underground roof support before, knowing that it is mainly used for mine roadway, secondary support of mine roadway, and support and support of mounta

We have a deep understanding of the appearance and use of U-shaped steel arch support, but we may have a little understanding of the material requirements of U tunnel roof support. Now let's make a de

The main characteristics of U29 steel arch support: bear pressure, support for a long time, easy to install, not easy to deformation and so on.

U-shaped steel arch support is a kind of passive support for underground roof support. It has high tensile strength and compressive strength, and has good toughness performance. It has high supporting
