Underground tunnel type steel beam row type steel beam type steel beam is the most commonly used roof beam in tunnel support. The type steel beam is made of two root steel beams butt welded through heat treatment, hence its 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 span of the beam, the concentrated load-bearing 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.
