DFB Long Metal Beam Profile DFB Long Metal Beam is a heavy duty non-articulated roof beams, DFB type can be used with all types of long metal beam monomer composition of the metal pillars with metal stents for the horizontal and gently coal mining face and head are inclined or other larger areas using roof control. DFB long metal beam can support long span cantilevered roof roof control area, to achieve a greater face without pillars supporting the work space, improve working conditions and the use of new coal mining machinery and flexible transport cashier favorable transformation condition. Parameter 1, the carrying capacity of the beam span of 700mm, the beam central concentrated load; 2.weight contains 0.7kg/m weld weight 3.Model specifications differ for each increase of one standard 200mm
