FRP(GRP) SERIES PRODUCT

A. Good safety property: No sparks out of direct cutting. It's convenient for the extraction operation, and can improve the coal output and safety property. B. High tensile strength: Tensile strength of the bar can reach 850Mpa, and every part of the bar has the same tensile strength. It can meet the requirement of the super-high strength. C. Strong anchoring strength: The strength is equated with the bar itself. D. Torque moment is more than 70 Nm, no breaking will happen even there is a crack. E. The bar is light: Weight of the bar is approx. 25% of the steel ones in the same specification. F. Anticorrosion and anti-ageing: It can be used for permanent supporting. G. No reflection to the electromagnetic wave: It's good for the concealing of the work. H. Strong load bearing ability: The load bearing ability of the thread can reach 10KN/cm.
