Steel Belt

We are offering w steel belt is a new type of structure and tunnel support material, the product can be combined with all kinds of bolt joint organization bolting, through it can scatter points dogan bolt joined up to form a whole bearing structure, significantly improve the overall effect of the anchor rod, in the incomplete roof strata, best to deal with instability of surrounding rock.
1, the bending section modulus increase 37 times;
2, about 70 times increase in steel intensity;
3, hardening effect in the process of cold rolling, and improve the tensile strength of 12% to 15%.
4, easy and dense paste of surrounding rock;
5, section utilization high, save material, low price.
