Key Takeaways

What is structural steel Tubing

Structural steel tubing is a type of steel tubing that is designed and manufactured for a variety of structural applications. It is commonly used in the construction of buildings, bridges, and other infrastructure projects. It is also used for industrial machinery and heavy equipment.

Structural steel tubing offers a high strength-to-weight ratio, excellent compression support characteristics, and torsional resistance. It is available in a wide range of sizes and shapes to meet the needs of any project. It also meets safety and performance requirements. Additionally, it is easy to fabricate, bend, form, punch, and drill. Its uniformity in terms of size, shape, strength, and tolerances makes it a preferred choice for Architecturally Exposed Structural Steel (AESS) applications.

This type of tubing has a wide range of uses and advantages, making it an ideal choice for a variety of projects. With its properties, dimensions, and other features, it can be used to create strong and reliable structures. Transitioning into the subsequent section, the structural tubing manufacturing process is another important aspect of this material.

Structural tubing manufacturing process

Manufacturing structural steel tubing involves a process of forming steel through a roller system and welding it together using electric-resistance welding. This provides a number of benefits, including superior strength-to-weight ratio, excellent compression support characteristics, and torsional resistance.

During the welding process, longitudinal butt joints are welded across the tubing’s thickness, which can then be custom cut and fabricated to meet specific requirements.

Tubing materials are available in a range of shapes and dimensions, including square and rectangular shapes between 0.500 to 16.000 with 0.065 to 0.625 wall thickness, and round shapes between 0.750 to 20.000 O.D. with 0.065 to 0.625 wall thickness. All tubing is fabricated according to ASTM A500 guidelines to ensure a quality product that meets safety and performance requirements.

In addition to the welding process, other fabrication techniques can be used to produce structural steel tubing. These include custom cutting, drilling, and forming to achieve the desired shape, size, and strength of the tubing. With the right fabrication techniques, structural steel tubing can be used in a variety of industries and applications, from construction and heavy equipment to architectural projects.

Benefits of structural tubing

Structural tubing offers numerous advantages that make it an ideal choice for a variety of applications.

It offers a high strength-to-weight ratio, excellent compression support characteristics, torsional resistance, and versatility in fabrication.

Additionally, it is compliant with safety and performance requirements and has a predictable size, shape, strength, and tolerance.

This makes it easy to work with and can be bent, formed, punched, and drilled.

Furthermore, structural tubing is designed to withstand harsh environmental conditions and is widely used in construction, heavy equipment, and AESS applications.


Following the discussion of the benefits of structural tubing, it is important to understand the specifications for this type of steel tubing. Structural steel grades, tubing dimensions, ASTM standards, welding techniques, and industry standards all apply to this type of tubing and must be adhered to in order to ensure a quality product.

These specifications must be taken into consideration when selecting structural steel tubing. With the right information and guidance, customers can trust that their products will meet the necessary standards.
