Square Steel Pipes - Steel Pipe ( Steel Tube ) – Rainbow
Square Steel Pipes - Steel Pipe ( Steel Tube ) – Rainbow Detail:
Round steel pipe
Description:
Welded steel pipes with hot dip coating or electric-galvanized coating on the surface of galvanized steel pipes. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, not only as pipelines for water, gas, oil and other general low-pressure fluids, but also as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters, condensation coolers, tubes for coal distillation and washing oil exchangers in chemical coking equipment, and tubes for trestle pipe piles and support frames in mine tunnels.

Hot Rolled Round Steel Tube
Hot rolled round steel tubes are measured by their outside diameter and their wall thickness. Their round structure allows them to have numerous types of architectural and structural applications. Hot rolled round steel tube is easy to cut, weld, form and machine.
Description:
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.
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.
Hot Rolled Square Steel Tubing Applications
Examples of applications for hot rolled square steel tube include:
Truck beds
Trailer beds and components
Frames
Machine parts
Furniture
Agricultural equipment
Safety and deck rails
Appliances
