(1) The rod body is light, easy to install and construct, reduce labor intensity and save transportation costs
(2) Strong corrosion resistance, strong acid and alkali environment resistance, does not reflect electromagnetic waves. It can meet the needs of permanent support.
(3) Easy to operate, easy to cut, cutting does not produce sparks, shearer has a certain protective effect.
(4) The strength is high, the anchoring force is large, and the tensile strength of the rod body is >=600Mpa, which is far greater than the strength of the steel bolt of the same specification.
We are a manufacturer and exporter specializing in providing supporting materials for coal mines, construction projects and large concrete projects. We mainly produce anchor rods, trays, resin anchors, mesh, W steel belts, u-beams, anchors and other supporting materials for coal mine projects, and our supporting materials are exported to more than ten countries and regions, such as the United States, Europe, Russia and so on. It is one of the important manufacturers and exporters of anchoring materials in China.
We have passed a series of certificates such as Quality Management System Certification and Environmental Management System Certification.
Our enterprise vision is: casting industry famous brand, building industrial and mining leading enterprises.
we can supply high-quality products to meet the requirements of top-ranking customers in this field from different countries in the world.
