The steel mine support is beneficial to improve the stress state of the support, improve its bearing capacity and maintain the stability of surrounding rock. In order to ensure the safety of mine prod

1, the roof support of the mine strong compression resistance, a good lane. The mine roof support of roadway is tightly connected with iron clip, so that the support structure is rigorous and the pre

U-shaped steel support has the advantages of high initial support force, large support strength, easy installation, and not easy deformation, etc., so it is often used in the manufacture of tunnel fle

The steel arch support solves the problem of tunneling support. Compared with other rigid supports, the steel arch has the flexible, stable and reliable bearing capacity, ADAPTS to the load and deform

The steel arch is divided into h-shaped steel arch frame, i-shaped steel arch frame, channel steel arch frame, miner's steel bracket and u-shaped steel bracket according to the production materials. M

1, channel steel is hot - rolled - shaped steel, U shaped steel is usually cold - rolled steel. 2. The detailed dimensions and mechanical properties of channel steel have been established into the na
