SpecificationSandwich system is used for buffering and releasing the pressure of the rocks to
protect the bolts from damaging and breaking. It could increase the
elongation of the bolts.Especially match with cable bolts to form a high
tensile strength,high elongation and high anti-shearing capacity
support system.This system is also match with Full threadbar bolt,Grooved bolt,Sharp end bolt,Slot&wedge bolt and so on.Please contact us if more details.
