Hot-rolled steel is steel pieces that have been roll-pressed at extremely high temperatures
Hot-rolled steel is steel pieces that have been roll-pressed at extremely high temperatures. Most operations process these pieces at well over 900°C (or 1,700˚F), which is over the recrystallization temperature for most kinds of steel.

USES OF HOT-ROLLED STEEL
ART AND ARCHITECTURE: Hot-rolled steel, once it has been fully processed and its surface has been smoothed, can be finished with all kinds of different methods. Hot-rolled steel in general also presents a unique finish — it has varying colors along the surface, which gives this kind of steel a lot of character. Because of this, it is the ideal material for artistic applications and structures, such as metal sculptures.
Architects also favor hot-rolled steel for certain architectural designs. It is aesthetically appealing in industrial and modern settings. Hot-rolled steel can be used to make light poles, racking, shelving, railing, fences, and more.
AUTOMOTIVE ENGINES AND PARTS:Hot-rolled steel can be used in the automotive industry and is typically used to make vehicle frames, engine components, and seat frames.
In these cases, hot-rolled steel needs further processing to withstand the corrosion and heat typical in automotive applications. This process is known as pickle and oiling (P&O), which is used to improve rust resistance and has the added benefit of allowing for painting.
AGRICULTURAL AND MINING EQUIPMENT:This kind of steel is also used widely in agricultural and mining equipment, due to its improved strength and formability. This allows manufacturers to make anything from simple bends to complex draws using hot-rolled steel.
Generally, you can find hot-rolled steel being used in the manufacturing of equipment like harvesters and tractors. They are also commonly used to make engine components and grouser bars.
BRIDGES AND INFRASTRUCTURE BUILDS:Hot-rolled steel’s strength and capability to be formed in large format pieces make it a great option for projects concerning infrastructure builds, such as bridges. Hot-rolled steel is frequently used to make structural sections, as well as components like grid decking and expansion joints.
MATERIAL HANDLING:Manufacturers prefer to use hot-rolled steel for certain material handling applications, such as components for fork trucks, trams, cranes, and elevators. This type of steel is typically used to make frames, rails, joint bars, and more.
WATER TRANSMISSION:Hot-rolled steel is also ideal for water transmission applications, such as making pipes and tubes. Hot-rolled steel can also be used for manufacturing additional components, like pipe couplings and spigot sections.
KEY TAKEAWAY:Depending on your metal project or application, the different types of steel will provide a different set of benefits and drawbacks. When it comes to hot-rolled steel and its uses, you can see that this material can be used as a building block for a wide variety of structural, industrial, and commercial applications.
Benefits of Hot Rolled Steel
Hot rolled steel offers several manufacturing advantages, such as:
- Lower cost: Hot rolled steel tends to be less expensive than cold rolled steel since it involves less processing.
- Better workability: As the hot rolling process occurs at elevated temperatures, the processed material is easy to form and shape.
- Little to no internal stress: The hot rolling process involves cooling the steel gradually, which allows the material to essentially normalize its structure and become free of internal stresses.
