Double-stranded hexagonal netting4. Constructions of hexagonal netting (GOST R 52132-2003) General informationDue to its construction specifics, steel netting is widely used in various industries: mechanical engineering, the building sector, metallurgy, the mineral resources industry, agriculture and the food industry. Its strength, elasticity, high transparency and capacity to hold up particles of given dimensions allows use of the nettings for:• granular materials classification based on particle dimensions;• conveyer belt manufacture;• fencing manufacture;• concrete reinforcing;• heat insulation;• plastering;• banks and shores consolidation, construction of special installations against landslides;• erosion-prevention and landscaping work.Steel nettings differ in wire material, wires connection type and mesh shape and dimensions.At present, joint-stock company “Severstal-metiz” offers the following nettings:• plaited nettings;• nettings welded at the intersection;• corrugated wire nettings;• landscape hexagonal nettings and constructions of hexagonal nettings.1) GOST = Russian State Standard2) TU = Technical Specification95Netting© Severstal-metiz, 2006. © Anordica AB, 2006.
