Row beam is the most commonly used top beam in roadway support. The row beam is formed by butt welding of two π-shaped steels after heat treatment, hence the name. Row beam is mainly used for roof support of coal mine roadway or roadway, and cooperates with single pillar to form metal support to support top beam.

Characteristics of line beam

1, row beam is a kind of non-articulated roof beam, which can be combined with various types of monomers and friction columns of articulated roof to form a metal support, which is used in horizontal and gently inclined coal mining faces, headstock or other large roof control areas in coal mines.

2. Long-span cantilever support with row beams controls the roof in the roof area, realizing a larger working space without pillars, and creating favorable conditions for improving working conditions and adopting new coal mining machinery and flexible conveyor.
