Product Description

PC Steel Wire:
Pc steel wire is mainly used for prestressed and post-tensioning technology in various shapes of prestressed concrete structures. And widely used for civil engineering construction such as large scale railroad, high-way bridges, buildings trusses, overhead crane beams, Industrial and prefabricated concrete floor, Wall board, tubular piles, PC water pipes, TV towers and nuclear power station, etc.
Active standard: GB/T5223, ASTMA421, BS5896, JISG3536, ISO6934, EN10138 or other special required standards.
