Concept: Steel wire rope, also known as steel cable, is a rope-shaped product made of high-quality steel wire through the processes of beating, twisting, and tying. It has light weight, high strength, good flexibility, strong impact resistance, and high-speed operation. Features such as noise, safe use, etc., are widely used in tensioning and fixing, transportation and traction, lifting and lifting.

Terminology

Steel wire is a round (or shaped) wire made of carbon steel or alloy steel through cold drawing or cold rolling, which is the basic unit of the strand. Generally speaking, the thicker the diameter of the steel wire, the stronger the abrasion resistance and wear resistance, the finer the diameter of the steel wire, the better the softness. Steel wire according to the cross-sectional shape can be divided into round and special-shaped such as Z-shaped, V-shaped, H-shaped, etc.; according to the surface state can be divided into smooth surface (no coating), plating (coating) layer (galvanized layer, aluminum coating, copper coating, plastic coating and other coatings). It is more common for galvanized layer, which can be divided into first pull after plating and first plating after pulling according to the coating method.

The surface of steel wire for steel wire rope is commonly divided into two kinds of smooth and galvanized, in the corrosive environment is weak, and allows the wire rope to be fully lubricated, the general use of smooth wire rope. Galvanized wire rope shall be used in corrosive environment and where it is not easy to grease the surface of the wire rope. The zinc coating is firmly attached to the surface of the steel wire and provides cathodic protection. Corrosion resistant long life. Galvanized steel wire rope is generally used in marine and other rainy and humid environments.

A wire rope is a wire bundle formed by a certain number of, one or more layers of steel wires.

The wire rope is covered with plastic and rubber.

Wire rope diameter refers to the specified value that represents the dimensional characteristics of the wire rope.

The minimum breaking force of the steel wire rope can be calculated by the formula of the nominal tensile strength of the steel wire and the structure of the steel wire rope.

Plating steel wire rope coating weight refers to the coating weight of the surface area of the surface steel wire, expressed in g/m2. There are provisions in the corresponding standards.
