The spiral strands are fabricated by successive spinning of layers generally opposite direction of helix, starting out with a straight core. All the wires are coated with galfan coating which is an alloy combining 95% zinc, 5% aluminum plus specific quantities of rare earth mischmetal. With excellent corrosion resistance and high axial stiffness, the spiral strand cable with galfan coating widely applied to structures like train station, stadium, convention center, membrane structure, glass curtain wall and bridge etc. Our company can produce the spiral strand cable diameter form 20mm to 160mm. The size of 160mm is by far the largest size that made in China. And it has passed the Hebei province scientific and technological achievements appraisal in 2012.
ADVANTAGES
1. Excellent corrosion resistance due to the galfan coating, which is 2-3time of normal galvanizing.
2. Self-compacting and with its metallic texture, it can well matched with the structures.
