SSTR51/550 Self Drilling High Strength Thread Stainless Steel Rock Anchor Rods
Features
SupAnchor stainless steel anchor rod benefits from superior strength, whilst retaining the elevated ductility associated with stainless steel. In coastal or aggressive environments, the traditional steel requires significant efforts to establish adequate corrosion protection. For projects requiring design lives in the region of 100 years, stainless steel provides practical solution.The system enables drilling and grouting in one operation, making much saving in jobsite and project time.
