galvanized steel wire

Galvanized steel wire is made of high-quality carbon structural steel such as 45#, 65#, 70#, etc., and then galvanized (electro-galvanized or hot-dip galvanized).

Galvanized steel wire is a carbon steel wire that is galvanized on the surface by hot-dip or electroplating. Its performance is the same as that of straightened and tempered steel wire. It can be used as unbonded prestressed tendons, but at least 200-300g of zinc should be plated per square meter. Commonly used as parallel steel wire cables for cable-stayed bridges (in addition, flexible cable sleeves are used as outer protection)

Physical Properties:

The surface of galvanized steel wire is smooth and clean, without cracks, knots, thorns, scars and rust. The tensile strength should be between 900Mpa-2200Mpa (wire diameter Φ0.2mm-Φ4.4mm). The number of twists (Φ0.5mm) should be more than 20 times, and the repeated bending should be more than 13 times.

The thickness of the hot-dip zinc layer is 250 g/m. Greatly improve the corrosion resistance of steel wire

use:

Galvanized steel wire is mainly used in the manufacture of greenhouses, farms, cotton baling, springs and wire ropes. It is suitable for engineering structures with harsh environmental conditions such as steel cables and sewage pools of cable-stayed bridges.

Drawing process:

Plating before drawing process: In order to improve the performance of galvanized steel wire, the process in which the steel wire is subjected to lead scorching, galvanizing and then drawing to the finished product is called the first plating and then drawing process. The typical process flow is: steel wire – lead quenching – galvanizing – drawing – finished steel wire. The process of first galvanizing and then drawing is the shortest process in the drawing method of galvanized steel wire, which can be used for drawing after hot-dip galvanizing or electro-galvanizing. Drawing after hot-dip galvanizing has better mechanical properties than drawing and plated steel wire first, and drawing after electro-galvanizing makes the zinc layer dense and resistant. Both can obtain a thin and uniform zinc layer, reduce zinc consumption and reduce the load of galvanizing line.
