ADVANTAGES
Galvanized PC Strand is a critical material in modern construction and infrastructure projects requiring high strength, low relaxation, and exceptional corrosion resistance. Its widespread use in bridges, marine structures, and prestressed concrete systems demonstrates its versatility and reliability.
By choosing galvanized PC strand, construction professionals ensure durable, long-lasting, and cost-effective solutions for demanding environments.
The strands are galvanized, with strong fatigue resistance and excellent corrosion resistance.
The process of single steel wire passing through the zinc bath is called hot-dip galvanizing, and the galvanized steel strand is twisted by 7 hot-dip galvanized steel wires.
The adhesion of zinc layer is checked according to the wrapping test of the galvanized steel wire before twisting or the central steel wire of the finished galvanized steel strand.
After 6 turns of winding, the zinc layer of the spiral ring shall not peel off.
