Product Details

4.9mm high tensile prestressed steel wire

Pc wire is mainly used for prestressed and posttensioning technology in various shapes of prestressed concrete structures,and widely used for civil engineering construction, such as large scale railroad, highway bridges, building trusses, overhead crane beams, industrial and prefabricated concrete floor, wall board, tubular piles, PC water pipes, TV towers and nuclearpower station, ETC. Active strandards:GB/T5223, ASTMA421, BS5896, JISG3536, ISO6934, EN10138 or other special required standards.
