There are two main ways to produce square tubes, namely, cold rolling and hot rolling. Square tube hot rolling is made by hot rolling strip steel through process processing.3×3 steel tube price
What’s hot rolling square tube？
Hot rolled steel pipes are manufactured by passing metal sheets through rolls to achieve specific physical dimensions. The finished product has a rough surface with rounded corners, welded or seamless structure.
The manufacture of hot rolled square steel tubes involves rolling the steel at temperatures in excess of 1000 °F, which is higher than the recrystallization temperature of the steel. This makes the steel easier to shape and form the tube. A potential disadvantage of this process is that once cooled, control of the finished product size is reduced. Due to these factors, hot rolled steel tubes are best suited for applications that do not require precise shapes or tight tolerances.
Advantages of using hot rolled steel tubes
Since hot rolled square steel tubes are less processed, they are generally cheaper than cold rolled steel tubes. Hot rolled steel is also more malleable, making it easier to bend and shape the tube into the shape you want. Due to its strength and durability, it is ideal for architectural and structural applications, but it is also versatile enough for a variety of commercial and industrial applications.
Hot rolled square steel tubes are durable and easy to form
Hot rolled square steel tubes are valued for their overall strength, durability and ability to withstand extreme temperatures, pressures and various elements. Square steel tubes are often used in home and industrial applications and are easy to weld, form and drill. The measurement considerations for hot rolled steel tubes include size, length and wall thickness.tinplate suppliers
