OEM/ODM Supplier Erw Carbon Steel Pipe - Steel Square Pipe – Rainbow Detail:

Hot rolled steel tubes are manufactured by passing sheet metal through rollers to achieve specific physical dimensions. The finished product has a rough surface finish with radiused corners, and either a welded or seamless construction.

Manufacturing hot rolled square steel tubing involves rolling the steel at temperatures exceeding 1,000°F, which is above steel’s recrystallization temperature.  This makes the steel easier to shape and form into a tube. A potential downside of the process is that there is less control over the dimensions of the finished product once it cools. Because of these factors, hot rolled steel tube is best suited for applications that do not require precise shapes or tight tolerances.

Advantages of Using Hot Rolled Steel Tubes

Since there is less processing involved with hot rolled square steel tubing, it is usually less expensive than cold rolled steel tubing.  Hot rolled steel is also more malleable, making it easier to bend and form the tubes into your desired shape. It is ideal for construction and structural applications because of its strength and durability, but it also versatile enough for use in a range of commercial and industrial applications.

Hot Rolled Square Steel Tube is Durable and Easy to Form

Hot rolled square steel tubing is valued for its overall strength, durability and ability to withstand extreme temperatures, pressures and a wide range of elements. Square steel tubing is regularly used for domestic and industrial applications and is easily welded, formed and drilled. Measurement considerations for hot rolled steel tubing include size, length, and wall thickness.

Hot Rolled Square Steel Tubing Applications
