The surface of galvanized steel wire is smooth, smooth and clean, without cracks, knots, pricks, scars and rust. The galvanized layer is uniform, with strong adhesion, durable corrosion resistance, and excellent toughness and elasticity. The tensile strength shall be between 900Mpa and 2200Mpa (wire diameter Φ 0.2mm- Φ 4.4mm)。 Number of twists（ Φ 0.5mm) for more than 20 times, and the repeated bending shall be more than 13 times.

The thickness of the hot-dip zinc coating is 250g/m. The corrosion resistance of steel wire is greatly improved.

Galvanized steel wire is mainly used for planting greenhouses, breeding farms, cotton packaging, spring and wire rope manufacturing. It is applicable to the cable of cable-stayed bridges, sewage tanks and other engineering structures with poor environmental conditions.

Quality standards for galvanized steel wire

Galvanizing layer-related standards: including zinc layer weight, uniformity and adhesion. Regarding zinc layer weight, different uses and specifications have different requirements. For example, when the thickness of the plated part is 3-4 millimeters, the zinc attachment amount should be less than 460 grams/meter (average thickness of no less than 65 micrometers), and for thickness greater than 4 millimeters, it should be no less than 610 grams/meter (average thickness of no less than 86 micrometers); uniformity can be tested by immersion in copper sulfate solution for five times without revealing iron; adhesion requires no detachment or protrusion after hammering test.

Dimension tolerance standards: The diameter must comply with the specified tolerance. The deviation standards vary for different industries. For example, the nominal diameter of hot-dip galvanized steel wire used for bridge cables allows a deviation of ±0.06 millimeters, and for 2.5 millimeter nominal diameter galvanized steel wire used for cotton packaging, the deviation is ±0.05 millimeters.
