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.

SupAnchor's self drilling anchor system provides efficient ground stabilization in challenging geology, with high-strength hollow bar anchors and corrosion protection for civil engineering projects.
SupAnchor introduces a corrosion-resistant GFRP solid bolt with high tensile strength, lightweight design, and non-conductive properties for slope stabilization, tunnel support, and mining applications.
A European transport project uses SupAnchor's self drilling anchor system to stabilize loose overburden and fractured rock. Hollow bar anchors provide immediate load capacity, corrosion protection, and long-term geotechnical safety.
SupAnchor introduces SupFRP® GFRP reinforcement rebar with high tensile strength, corrosion resistance, and versatile shapes for demanding construction applications across Europe and North America.
SupAnchor introduces a stainless steel self-drilling hollow anchor combining 3-in-1 drilling, grouting, and reinforcing with superior corrosion resistance for marine, chemical, and permanent geotechnical applications.
