Profile beam product introduction

The row beam is the most commonly used roof beam in the roadway support. The row beam is made of two π-shaped steels after heat treatment butt welding, so its name comes from this. The row beam is mainly used for the roof support of coal mine tunnels or roadways. The metal bracket is combined with the single pillar to support the roof beam.

Row beam parameters

1: Material: 27simn
2: width 100mm. Height 90mm thickness: 8mm
3. When the bearing capacity is 700mm, the load is concentrated in the center of the beam;
4. Weld weight with weight of 0.7kg / m;
5.Add a specification for each 200mm difference in the model specifications

Row Beam Advantage

1. The row beam is a non-articulated roof beam. It can be used with various types of single-piece and friction pillars with hinged roofs to cooperate with metal brackets for coal mines in horizontal and gently inclined mining working faces and heads or other Use larger control area.
2. The long-span cantilever support of the row beam supports the roof of the control area to realize a large working space without pillar support, which has created favorable conditions for improving labor conditions and the use of new coal mining machinery and flexible conveyors.
