Steel Bar Factory

Custom manufacturer & distributor of stainless & alloy steel bars. Products include round & square bar in standard and custom lengths. Secondary services include shearing, slitting, machining & coating. Serves aerospace, automotive, marine & construction industries. Meets AMS standards.

Once the hot bar has cooled down it is cut by a flying shear into customer specific lengths on the cooling bed and then sheared again to its final size.

Metallurgical Process

The process of creating steel bars starts with a steel billet. These are long, cylindrical pieces of metal that have a square or rectangular cross-section and are the building blocks for a wide variety of steel bar types. These bars, also known as reinforcing bars (rebar), are used in many construction applications including concrete reinforcement and a wide range of industrial uses. The quality and consistency of the billets have a direct impact on the final qualities of the steel bars.

A steel mill starts with molten iron and the raw materials needed to make it into a specific type of steel. This is done in a Basic Oxygen Furnace, or BOF for short. The BOF is a refractory lined vessel with an open top that allows for rapid refining of the molten iron. This is achieved by the combination of oxygen with the iron, and the removal of carbon in this way.

Once the molten metal has reached its desired chemistry, it is tapped into a ladle and transferred to a hot-rolling mill. The resulting rolled product is called a hot bar and is sheared to customer specific lengths before cooling on a cooling bed.

Choosing the right steel company to produce your steel bars can make all the difference in the finished product. Companies like Wuxi Kongzo Steel have a commitment to quality and are an ISO 9001:2008 certified company. They are a trusted partner for construction projects and steel fabricators.

Rolling Process

Steel bars are rolled to achieve the desired shapes, thicknesses and sizes. During the rolling process, the molten metal passes between two rotating rolls that apply high compressive forces to plastically deform the material. The resulting deformation changes the shape and size of the work-piece, as well as its grain structure.

The rolling process can take place at different temperatures depending on the application. It is usually done at temperatures above the recrystallization temperature. This allows for a high degree of reduction in height and width with moderate forming pressures. The process can produce blooms, slabs, billets, plates and structural shapes as well as sheet and strip.

Once the steel has been rolled, it is immediately quenched in water to avoid oxidation steel bar factory and retain its properties. The water-quenching process is a critical stage in the manufacturing of steel products. It is performed by experts using patented thermex systems to ensure quality control and proper water-quenching conditions.

The rod and wire that are produced during the rolling process must meet specific metallurgical requirements to ensure quality. They must be free of defects such as cracks, folds and ears. The steel also needs to have the right mechanical properties and a smooth surface. In addition, it must be properly coiled and cooled before bundling. The cooling condition is carefully controlled to ensure that the rod and wire meet metallurgical requirements.

Heat Treatment

When it comes to the manufacture of a quality steel bar, heat treatment is an essential part of the process. It can improve the mechanical properties of the metal and help it withstand extreme conditions. It also increases the machinability of the steel bars.

In this process, the steel rebars are heated to a high temperature and then quickly cooled using water. This is known as quenching, and it is used to increase the hardness of the steel. In addition, the rapid cooling of the rebars also helps to prevent cracking and internal stresses.

During the heating stage, the steel is carefully monitored stainless steel plate manufacturers to ensure that it doesn’t reach its melting point. The temperature is also controlled to ensure that each section of the metal gets heated evenly and does not become weakened by overheating.

ARS is an ISO 9001:2008 certified company that specializes in manufacturing steel bars and products for the construction industry. Their thermo-mechanically treated steel (TMT) bars are strong and ductile, making them ideal for use in massive construction projects. This is achieved through a unique technique that leaves the bars with a tough outer layer and a soft inner core. The bars are then sheared to customer-specific lengths before being sent onto a cooling bed. ARS’s high-quality bars are used in a wide range of applications, including construction, engineering, and manufacturing.


Once the raw materials are melted in the furnace, they are cast into semi-finished shapes called billets. These billets go through a hot rolling process to become the long, thin steel bars that are used for various applications. The length of the bar is determined by the customer and the product they need to make, but the standard sizes include round, square, rectangle, hex (A/F), and channel bar.

The finished steel bar is usually stamped with identifying information and the producing mill. The bar is also subjected to a process called quenching. This fine-tunes the hardness and ductility of the bar, ensuring that it will meet the desired specifications. It also makes the surface of the bar shiny, which is important for reinforcing applications.

Rogue Fitness sources its steel from the Niagara LaSalle Corporation, and it has to undergo processing before they can sell it to us. That processing is done through a series of steps that includes cold drawing, turning, grinding and polishing, elevated temperature drawing, thermal treatment, and combined processing.

The resulting products are cold drawn finished steel bars, which are created by passing the steel through a die that reduces the diameter of the steel and forms it into a specific shape. The resulting product is highly conductive and has excellent mechanical properties. It is a critical component of many industrial and manufacturing processes, including forming, welding, and cutting metals.
