Wen Ma Highway (from Wen Chuan to Ma Er Kang), as an important passage for economy and life from mainland China to Tibet, the project is 174 km long, crossing mountains and rivers, bridges and tunnels are occupied 85% of the whole project, and the tunnel and slope reinforcement job is very complicated due to difficult stratum.
We put a large quantity of Self Drilling Hollow Bar R32N/18.5–4m in WenMa expressway construction. Our products have helped the contractor efficiently solve the anchoring problem when drilling into the loose rock and soil.Our reliable quality and supply provided much reliability and safety for the project.
