Concrete strand is a high-strength steel cable used for prestressing and reinforcing concrete structures in bridges, tunnels, and industrial buildings. It is made of high-tensile carbon steel wires with tensile strength between 1570 and 1960 N/mm², typically arranged as 7 wires twisted around a steel core 7-wire strand. Individual wire diameters range from 4.5 to 15.2 mm, with overall strand diameters from 12.7 to 15.2 mm. Wire surfaces are coated with oil, wax, or galvanization to enhance corrosion resistance and ensure long-term durability of the structure.
Structurally, concrete strands provide sufficient flexibility for twisting and tensioning while offering high radial strength against tensile and shear forces. Wires are precisely and uniformly twisted to optimize stress distribution along the strand. Standard strand lengths range from 12 to 250 meters and operate reliably in temperatures from −40°C to +80°C. It is widely used in bridges, concrete slabs, tunnels, and prestressed construction projects, ensuring structural safety, stability, and longevity.You can order and buy Spiral Rope from Iran by contacting us through whatsaap and email.

Applications of Concrete Strands in Bridges, Tunnels, and Buildings
Concrete strands, or prestressing wires, are widely used in bridges, tunnels, and buildings due to high tensile strength and load-bearing capacity. In bridge construction, strands resist tensile stress in beams and prestressed slabs, enhancing structural stability. In tunnels, they help control cracking and settlement. In high-rise buildings and concrete slabs, strands allow reduced slab thickness and longer spans without additional columns. Proper selection of diameter, strand count, and prestressing force ensures project longevity and safety.
