Steel Wire

Sino East steel, provides so many kinds of steel products according to its main four of categories such as steel pipe, steel sheet, structural steel and steel wire rods. As a leading manufacturer of steel products in China, the company has ensure its products’ quality and sufficient stock for domestic and abroad customers. Meanwhile, steel wire products already have sold to worldwide with numerous buyers in long term. Based on this, there is the concrete introduction about steel wire. Actually, steel wire is the reprocessed product made of hot-rolled wire rod by cold drawing, with the shape including round, oval, square, and hexagon in accordance with its cross section. The most time, there is the confusion between steel wires and steel wire rods.

So What Is The Difference?

Before we understand the difference for both, how to understand about wire rods is primary. As common sense and popular view, indeed round steel bar is the wire rod. It means that wire rods roll into coil, then it is straightened when the need of construction, usually less than 10mm of diameter. According to the size of diameter, namely thickness, it can be divided into Round steel, Steel bar, Wire rod and Rod.

• Round Steel

It means the steel bar with diameter of cross section greater than 8mm.

• Steel bar

It means that steel products as straight bar with the cross-section shape as round, hexagonal, square or other special-shaped.

• Wire rods

The wire rods with circle cross-section, a diameter of 5.5 to 30mm. If only considers to wire products, it will refers to steel wire which is a steel product reprocessed by steel wire rod.

• Rod

Wire rod as finished products with hot-rolled process coiled for delivery. It is included round, square, rectangular, hexagonal, etc. Because most of them are round shape, so generally speaking, wire rod refers to circular wire rod.

Classification of Steel Wire

For the classification of steel wire, we may consider to classify as its materials and coating, size, strength and uses. List the sorts below,

• Materials and coatings

There are low carbon iron wire, high carbon steel wire, stainless steel wire, coated steel wire (galvanized steel wire, zinc-electroplated steel wire galvalume steel wire and copper plated steel wire), etc.

• According to size

Less than 0.1mm, 0.1 to 0.5mm, 0.5 to 1.5mm, 1.5 to 3.0mm, 3.0 to 6.0mm, 6.0 to 8.0mm and larger than 8.0mm.

According to strength

Less than 390Mpa, 390 to 785Mpa, 785 to 1,225Mpa, 1,225 to 1,960Mpa, 1,960 to 3,135Mpa, larger than 3,135Mpa.

• According to uses

It is divided into common quality steel wire (welding rod, steel nail, mesh, steel wire for packing and printing); Steel wire for cold upsetting; Electrical steel wire; Steel wire for textile industry; Wire rope making (wire rope, PC strand and spoke); Spring wire includes spring and spring washer; Steel wire for piano, tyres, cord fabric and conveyor belt; Structural steel wire, etc.

Advantages of Steel Wires

Steel wire products as one kind of common products for many industries, projects, are really matched to a lot of advantages such as its tensile strength, stiffness, corrosion resistance of coated steel wire, workability such as bending and twisting, etc.

• Carbon steel wire because of its carbon content, gives its strength and tensile strength, however it lowers the malleability. This will result in corresponding difficulties like bending, forming, twisting process. Certainly, proper thermal treatment will assist in these problems.
• Coated steel wire, such as galvanized steel wire, external plastic coating, galvalume steel wire, aluminum-plated steel wire, would meet to higher corrosion resistance.
