Stable and Compacted Galvanized Steel Strand for Concrete
Galvanized steel strands, also called galvanized stranded wires, which are twisted together by several galvanized steel wires. Among different steel wire strands, 1 × 3, 1 × 7, 1 × 19 galvanized stranded wire are the most popular. Because they are made by means of wire drawing followed by hot-dipped galvanizing or electrical galvanizing, the surface of the strands has a layer of zinc. Therefore, the strands have extremely excellent nature, such as excellent abrasion resistance, high tensile strength and corrosion resistance.
Cross sectional area of 1 × 3 galvanized steel strand. The wire diameter sizes from 0.8 mm to 7.60 mm. The strand sizes from 5.4 mm to 17.8 mm.
Cross sectional area of 1 × 7 galvanized steel strand. The structures of strand are available in 1 × 37, 1 × 25, 1 × 19, 1 × 7, 1 × 4, 1 × 3 & 1 × 2.
