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.

A highway widening project in mountainous terrain deploys SupAnchor's self drilling anchor system to combat fractured geology, ensuring long-term stability with advanced corrosion protection and high tensile strength.
SupAnchor's SupUTS self-drilling hollow anchor system delivers up to 930 kN tensile strength for deep foundations, tunnels, and slope stabilization. Integrated 3-in-1 design and triple corrosion protection
A recent construction project utilized SupAnchor's self-drilling anchor bolts to stabilize loose soils and rock, showcasing advanced geotechnical reinforcement solutions for demanding civil engineering works.
SupAnchor unveils a corrosion-resistant GFRP solid bolt with up to 500kN tensile strength for slope stabilization, tunneling, and mining. Lightweight, non-conductive, and maintenance-free solution.
Innovative self-drilling anchor system by SupAnchor overcomes difficult geology in a vital infrastructure project, enhancing safety and efficiency.
