Prestressed PC Stranded Wire for Construction

Firstlin supplies and exports pre-stressed steel wire strands for concrete constructions. Processed from high tensile steel wire materials. Following models listed for reference, while a wide range of sizes available.

Electro Galvanized Steel Strand

Galvanized Steel Strand - 1X7 - 0.4mm PC Stranded Wire

Electro Galv Steel Strand Description

Electro Galvanized Steel Strand 1X7 0.4mm stranded wire with ± 0.02mm allowable offset, 1.2mm diameter.
Nominal strength or extension 1100MPa.
Weight of zinc coating for steel wire: heavier than 10G/M2.
Material: Galv. Wire

Technical Notes:

Cross section construction 1X7. The allowed offset of diameter is 0.05mm.
Nominal diameter of wire 0.4 to 0.6 mm. ± 0.02mm allowed offset of diameter. Ovality of singe zinc-coated wire cannot be greater than half the diameter tolerance.
Lay length of steel strand should be 10 ti 15 times longer than its diameter. Twist direction of outer wire should be right and defaults to opposite for the adjacent layer of steel wire.
Wire shall be free of any welding. NO WELDING IS ALLOWED.
Wire must be zinc coated heavier than 10G/M2.
