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.

Functions:It  is an effective rock reinforcement system for underground roof support.  If there is rock mass deformation, the paddle part will be worked as  anchor points to bear the load and smooth section will absorb energy to  prevent rock fall.Features&Advantages:1.After fully grouted in the bore hole, the paddle part will work as anchor points.

Wire Mesh Strap Support Features:1.High energy absorbing.2.Pig tail cross wire design allows for multiple take upon bolts.3.Allows for movement without weakening the integral mesh strength.4.The longitudinal wire strand is able to slip under load conditions through the  cross wires to distribute load over several bolts.5.Available in black or hot dip galvanized.
