Advantages:
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 bolt can reach 850Mpa, and every part of the bolt has the same tensile strength. It can meet the requirement of the super-high strength.
C.Strong anchoring strength: The strength is equated with it of the bolt.
D.Torque moment is more than 70 Nm, no breaking will happen even there is a crack.
E.The bolt is light: Weight of the bolt 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.
