Thread Bar Rock Bolts

All Thread Bar Rock Bolts are used together with dome plate and net for reliable ground support in mines, tunnels, slopes, or wherever.
1. Features of Thread Bar Rock Bolts :
(1)The Bar has closely defined mechanical properties which provide consistent performance under long term anchor loading.
(2) In the longitudinal direcition , rock body has equal tensile strength ,that is about 40% higher than the reverse-twist bolt in the same specification .
(3) Extend the support area , not only be used by end anchoring ,but also be used by fully anchoring ,that has a better support efficiency.
(4) Low price, widely used in coal mines, railways, hydropower and other types of roadway projects.
(5) Thread profile offers excellent mixing capabilities in resins installation
(6) The high ductility and smooth, relatively flat rate of strain hardening ensures a high margin of safety against tensile/shear overload in the case of transverse movements in the rock soil.
(7) Can be cut and spliced at any point along its length.
