Underground profiled steel beams Profiled steel beam specifications Profiled steel beams are the most commonly used roof beams in tunnel support. Profiled steel beams are made of two root sections butt-welded by heat treatment, hence their name. Profiled steel beams are mainly used for roof support in coal mine tunnels or tunnels. They are combined with single pillars to form a metal bracket to support the roof beam. The beams produced by our factory have been heated and quenched and tempered, fully complying with national technical standards.
The profiled steel beam can cantilever-support the roof of the control area over a long span, allowing a larger working space without pillar support on the working surface. This is in order to improve working conditions and adopt new coal mining machinery and bendable conveyor cashier transformation. favorable conditions.

Precautions for profiled steel beams
, weight including weld weight
, add one specification for each difference in model specification
, when the bearing capacity is the beam span, the concentrated load-bearing type steel beam in the center of the beam is used in coal mines in horizontal and gently sloping mining working faces and machine heads or other large roof control areas.
