Good quality and price Reasonably, this type of roof beam is a hinged roof beam, which can be matched with various types of single metal pillars to form a metal bracket. It is a high-strength roof beam used for supporting horizontal and gently inclined mining working faces in coal mines. Because this kind of roof beam can cantilever support the roof above the conveyor road in front of the coal wall of the working face, there is a large unsupported space between the coal wall and the pillars. Therefore, it provides conditions for the use of new coal mining machinery and flexible transporters to achieve general mechanization of coal mining. It is a necessary supporting equipment for high-end general mining and new high-end mining technology
