Galvanized Steel Wire gj-50

Strand Strand points classification prestressing strand, unbonded strand, galvanized steel, etc., different strand have different performance characteristics. The most common strand of galvanized steel and pre-stressed strand, common prestressing strand diameter of 9.53mm-17.8mm range, there are a few more rough strand diameter. Each prestressing strand of wire is typically 7, there are 2, 3 and 19, may have a metal or non-metallic coating on the wire. After the anti-corrosion coating of oil or paraffin HDPE called unbonded prestressing strand (unbonded steel strand). Use galvanized steel usually refers to catenary, cable, strengthen the core, etc., it can be used as overhead transmission ground, blocking the cable or structures on both sides of the road construction on request. Prestressing strand prestressing strand is commonly used in uncoated low relaxation pre-stressed strand, there are galvanized, commonly used in bridges, buildings, water, energy and geotechnical engineering, unbonded prestressed Strand commonly used in the floor, foundation engineering. Prestressing strand we talk about now mainly used in bridges, buildings, water, energy and geotechnical engineering, prestressing strand prestressing strand by 2,3,7 or 19 high-strength steel consisting of twisted rope, and by stress relief treatment (stabilizing treatment), for prestressed concrete or similar purposes.
