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 major infrastructure project has deployed self drilling anchor bolts and hollow bar anchors to stabilize slopes and foundations in difficult ground conditions, highlighting the growing role of geotechnical reinforcement systems.
SupAnchor's new Grade 75 self-drilling hollow anchor offers enhanced load-bearing capacity for heavy-duty infrastructure, tunneling, and slope stabilization, combining high-strength steel with the proven 3-in-1 drill-and-grout system.
SupAnchor's self-drilling anchor system is being used in a major European infrastructure project, addressing challenging ground conditions and ensuring long-term stability.
SupAnchor's new GFRP reinforcement rebar offers high tensile strength, corrosion resistance, and non-magnetic properties for concrete structures in harsh environments.
SupAnchor's hollow bar anchor technology provides reliable geotechnical reinforcement in a challenging slope stabilization project, highlighting industry trends in ground stabilization.
