π steel is mainly used for the production π main beams, metal roof beams, hinged roof beams and other mining support beam, in the coal mine (mine) tunnel (tunnel) plays a supporting role in π steel because of its cross-section like the letter \"π \"character named. π steel structure is a face and two legs, of which the surface is flanked by jagged lace.
πSteel Product Feature
7 # π steel which can be used with all types of monomers, metal pillar with the composition of metal stents for the horizontal and gently coal mining face and head are inclined or other large areas using roof control. It can support long span and cantilevered 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 transformation favorable conditions.
