Product Details

prestressed concrete steel plain /spiral ribbed PC wire

STEEL WIRE (PC WIRE) FOR PRESTRESSED CONCRETE

This products is mainly used for prestressed and post-tensioning technology in various shapes of prestressed concrete structures. And widely use for civil engineering construction such as large scale railroad, high-way bridges, buildings trussed, overhead crane beams, industrial and prefabricated concrete floor, wall board, tubular pipes, PC water pipes, TV towers and nuclear power station etc.

Active standard:GB/T5223, ASTM A421, BS5896, JIS G3536, ISO6934, EN10138 or other special required standards.

GB/T5223-2002 Technical standards for PC Wire.
