No Pollution And No Emission
The total length of the full thread of the bolt is equal to the full length of the bolt of the same specification, and the bearing capacity of the bolt is increased by 40%. The use range of bolts is expanded, and end anchors, extended anchors and full anchors can be realized; the operation is simple and the price is low.
The whole length of the rod body has continuous thread compression, and the strength of the whole length is equal; the prestressed washer and the spherical nut are installed on the tightening end. Fiber reinforced plastic FRP mine bolt is made of glass fiber yarn, resin and curing agent through extrusion, stretching and high temperature curing. The shape of the FRP bolt is full thread, and the thread can be left-handed or right-handed.
The bolt has the properties of high tensile strength, easy cutting, no damage to teeth, no sparks, safe mining efficiency, light weight, corrosion resistance, flame retardant, antistatic and other properties. It can be permanently supported and can replace the metal bolt reinforced composite material.
