Steel ring net for structural applications
3SGEOTECH® has introduced a new production line to manufacture the steel ring net type 3SRINGNET®. This ring net has been traditionally used in geotechnical applications, mainly as catchment surface inside protection systems against rockfall and debris flows.
High strength steel wire rings
3SRINGNET® is produced by interlacing seamless steel rings. These steel rings are made of galvanized high strength steel wire. 3SRINGNET® can be produced in configuration of 4 or 6 contacts, depending on steel ring arrangement with neighbors rings and established during the manufacturing process.
High corrosion protection
3SGEOTECH® can produce a wide range of steel ring nets type 3SRINGNET® with different sizes, configurations and types of galvanization. In this way, ring nets can be produced according the specific requirements, especially the corrosion protection according the environment.
