The ultra-high load, ultra-high strength heat-treated bolt/roof support system is an advanced steel product with high quality and performance, capable of ensuring effective anchoring against complex ground conditions such as gravel, inconsistent filling, boulders, crushed stone, and weathered rock. The raw material consists of hot-rolled steel bars or deformed steel bars, utilizing induction heat treatment technology (our patent). This product is widely used in tunnel construction, mining, slope stability, and foundation support.
The high-strength rock bolt produced by our company has a higher strength grade than ordinary hot-rolled rebar. This advantage reduces rock deformation and controls or limits the broken area of the surrounding rock. It also has good impact resistance, allowing it to withstand sudden impact pressure and ensure the safety of mining operations
