High Corrosive Invironment SDA Rock Drilling Stainless Steel Anchor Rods SST52/1250
Features
In general it is reasonable to use grade 304 for most non-marine applications, highways and marine structures generally call for grade 316 because of high chloride concentrations.
SupAnchor stainless steel anchor rod benefits from superior strength, whilst retaining the elevated ductility associated with stainless steel.
The system enables drilling and grouting in one operation, making much saving in jobsite and project time.
High corrosion resistance
Tensile Strength (N/mm2 ) >= 1000 N/mm2
100+ year service life
Applications
Tunneling & mining
Foundation
Docks and harbours
Coastal defence walls
Soil nails
Building and bridge cross ties
Ground anchors
