The anti-corrosion rock bolts of sinorock® include hot dip galvanized bolt and stainless steel bolt. Hot dip galvanizing bolt adopts hot dip galvanizing process. After the burr is cleaned on the bolt, it is dipped and plated. Zinc is easily oxidized, forming a dense oxide layer on the surface of the bolt to prevent the internal rod from being corroded. Stainless steel bolt is a kind of alloy steel anchor bolt, which contains more than 10.5% of chromium. Chromium and zinc, which are corrosion resistant metals, can resist the corrosion of air or chemical corrosion conditions. We have strict quality control to ensure the durability of the anti-corrosion anchor bolts. During construction, the rock bolt is permanently buried in rock or soil, and its life depends on the durability of the rod and affects the quality of the whole project. There are many factors that affect the durability of the rock bolt, such as excessive previous stressed tonnage, material, improper construction process and environmental corrosion, among which the biggest threat is corrosion. The protection period of the rock bolt is the effective period of the bolt. Once it is corroded, it will lose its protective effect, and it is necessary to re-support the project. Therefore, it is of great importance to prevent corrosion of the rock bolt. Sinorock® has been continuously improving, making the durability of anti-corrosion self drilling bolts getting better and better.
