12.7mm Prestressing Post Tensioned PC Strand
Description of Prestressing Post-Tensioned PC Strand
Tensioning stranded wire is a steel product composed of multiple steel wires. The surface of carbon steel can be added with galvanized layer, zinc-aluminum alloy layer, aluminum-clad layer, copper-plated layer, and epoxy resin coating.
Galvanized steel strand is usually used for load-bearing cable, stay wire, reinforcing core, etc. It can also be used as the ground wire of overhead power transmission to block the cables on both sides of the road or the structural cables in the building structure. The commonly used prestressed steel strands are uncoated low relaxation prestressed steel strands, and some are galvanized.

Advantages of Post-Tensioned PC Strands
Stranded steel cable composed of multiple high-strength steel wires and treated with stress relief (stabilization treatment), suitable for prestressed concrete or similar applications, with saving steel, high tensile strength, good elongation, low relaxation, stress With the characteristics of small loss and excellent fatigue resistance, it is a product with high technical content and good quality among high-efficiency steel products. PC steel strands are widely used in highways, bridges, sleepers, large stadiums, high-rise buildings, airports, ports, wharves, nuclear power plants, dams, urban elevated and light rail, and other infrastructure construction fields.
Application of High Tension Strands Steel Wire Galvanized
It is commonly used in highway bridges, railway bridges, urban overpasses, urban light rail, high-rise buildings, water conservancy, hydropower dams, port terminals, rock slope protection anchorage, foundation reinforcement, tunnel roof anchorage, prestressed grid, subway, large buildings, warehouses, tower buildings, heavy lifting, sliding film intermittent jacking, bridge and tunnel jacking, large containers and ships, sleeper, bridge support replacement, bridge, and building reinforcement.
