What is steel wire rod?

Steel Wire Rod is a long piece of steel that is hot rolled and when cooled, it gets wound into a coil. There are different types of shapes such as round, square, semicircle, and hexagonal.

• Steel wire rods are almost identical to GI or galvanized iron wires.
• They look very similar, but different materials form steel wire rods than galvanized iron. Also, the manufacturing of each varies.
• Billets function as a steel to produce steel wire rods.

How to Manufacture steel wire rod?

Billets are considered semi-finished metal pieces. When processed further, the semi-finished pieces become valued products. There are many steps in the process of manufacturing steel wire rod including:

• Billets usually come in the form of a square, circle, or rectangle which has areas below 36 sq. inches. A process called extrusion is how wire rods are produced. The billets push through a die. Then, the billets mold into the shape of the die opening.
• The dies, which can be circular, rectangular, or square-shaped, have a typical diameter from 5 – 42 millimeters.
• The billets are not pre-heated before going through the dies but heated as they pass within the molds.
• At the end of the extrusion process, the semi-finished wire rods then go through a specialized winder which winds the wire rods into loose coil stacks.
• Since the freshly wound wire rods are still hot, they are cooled using either air or a forced cooling process. The forced cooling process makes use of large fans, while the other one uses the surrounding air without the use of any cooling machine.
• The wire rods are glowing red hot after the whole extrusion and winding process which is why accelerated cooling is more preferred, or else a lengthy amount of cooling time will be required.

What are the main specifications for steel wire rods?

• Wire rods are produced with different grades. These grades each have their own specifications and corresponding applications. These specifications help the end-user or other manufacturers in choosing which grade of wire rods to purchase.
• For an SAE 1008 wire rod, grades include Q195, Q215, Q235, 1006B, 1008B, 1012B, 1017B, and 1018B. The Q195, Q215, Q235 grades are used primarily in the field of construction and drawing wires.
• The diameter sizes of each grade are as follows:

What are the Chemical Composition and Mechanical Properties of typical steel wire rod?

A typical steel wire rod has a chemical composition of the following:

• Carbon
• Manganese
• Silicon
• Phosphorous
• Sulfur
• Boron

Its mechanical properties are as follows:

What are the main applications of steel wire rod?

1. Steel wire rods have many potential applications, mainly

• wire drawing
• construction uses
• tools manufacturing

GI or galvanized iron wires are actually made from steel wire rods which have been coated by zinc in order to prevent it from corrosion and rusting.

Steel wire rods are also used to manufacture nails and other construction materials.

Where to Buy steel wire rod

You may be able to find Steel Wire Rod in small quantities in your area. But if you want to buy large quantities of steel wire rod, it is preferable to import directly from the manufacturers. They can issue certifications and provide cost savings which is better than buying the steel in small quantities locally or from a distributor.

If you require bulk quantities of this steel, you can buy Steel Wire Rod on our website.

What is a rebar?

• Rebar, which stands for reinforcing bar, is also known to the general public as reinforcing steel.
• Rebar is typically what you will mostly see on establishments and buildings which as being constructed.
• These are steel-type rods which are used to generally reinforce the foundations of a structure. It is found in any construction which uses concrete as its base foundations since rebar strengthens it.
• Rebar acts as the bonding agent that helps keep the concrete foundations from crumbling under large stresses and loads.

How is rebar manufactured?

• The production process of rebar is very simple and requires extreme heat.
• To make these, steel is heated down until melted and then pushed into circular openings of a certain diameter.
• One of the distinguishing factors of rebar is that it has a “rib” design.
• This adds to the bonding strength of the concrete and prevents it from slipping out of place.

What materials are used in the manufacture of rebar?

• Carbon steel is commonly the material used when making rebar.
• Although, there are also rebar made from stainless steel, carbon fiber, glass fiber, or sometime basalt fiber.
• Since rebar is a type of unfinished steel, it has the tendency to corrode and rust. Because of this some manufacturers of rebar coat them with epoxy or stainless steel.

What are the common types of rebar for sale?

Epoxy coated Rebar – This type is expensive and is usually used within foundations that are submerged in water, particularly saltwater. The epoxy coating protects it from any corrosion or rusting.

Carbon Steel Rebar – This is considered the cheapest and affordable type of rebar. In terms of strength, it is up to par but since it has no protective coating, it is subjected to corrosion and rusting. Regardless of this, it is still the most commonly used in any type of construction.

Stainless Steel Rebar–This type is used alternatively from carbon steel. Since it is stainless, it is automatically immune to rust and corrosion although they are more expensive than the epoxy-coated type.

What are the main specifications of rebar?

• As with other construction materials used, rebar is classified into grades and sizes.
• Rebar is available for sale in various diameters and lengths depending on the application
• The steel type of rebar is required and has the same coefficient of thermal expansion as that of the concrete it is used with.
• This is a very important specification that needs to be taken into account when choosing the right type of rebar. If the coefficient is different, they rebar, and concrete will expand at a different rate, which is highly dangerous and prone to the cracking of the concrete.
• Rebar is commonly made with diameters from 6 mm to 57 mm

What are the Chemical Composition and Mechanical Properties of typical rebar?

• The different types of rebar basically have the same chemical composition.
• They consist of manganese, silicon, alloy, carbon, and many more.
• Some type of rebar is coated with outer protection like epoxy and stainless steel.
• Common mechanical properties of rebar are as follows:

What are the main applications of rebar?

• Rebar is generally used in the field of construction to reinforce concrete structures like slabs and foundations.
• Rebar increases the concrete’s tensile strength so that it can withstand prolonged exposure to tension and compression forces.
• Practically every major modern construction site uses rebar for construction. You can think of rebar as the actual mold of the structures.
