U Steel Arch

U Steel Arch is commonly used to manufacture tunnel retractable metal support, which is used for mine roadway, secondary support of mine roadway, and support of mountain tunnel.

The use of U-shaped steel support effectively reduces the occurrence of roof fall, sheet wall and other accidents, is safe and reliable, and improves the stability of the mine ventilation system. U-shaped steel retractable support is selected to solve the problem of driving support.

FEATURES & ADVANTAGES

high support strength, simple installation, and not easy to deform.

Tunnel arches in mine tunnels and roadways supporting provides not only a higher resistance but also a yielding support. When the surrounding ground reaches a certain degree, avoiding arch failure.

U profile steel arches instead of other frames, timber ones or different steel sections, in mining operations have these advantages:

Higher resistance against transversal and longitudinal stresses.

Allow a very high roadway section convergency.

Easy and fast assembling.

Can be re-used after recovery and cold forming.

Application

safe and reliable,widely used in mine tunnel.
