A500 Hollow Structural Steel (HSS) Tubing

Structural steel tubing is hollow, round, square, or rectangular steel used in load‑bearing construction. Its welded design delivers high strength, durability, and easy fabrication for columns, beams, braces, and frameworks, while the hollow form reduces weight and allows utilities to pass through.

Benefits of Structural Steel Tubing

  • Strength - Structural steel tubing exhibits an exceptional strength-to-weight ratio, which empowers it to withstand substantial loads while simultaneously diminishing the total weight of the structure.
  • Uniformity - HSS plays a critical role in OEM applications by guaranteeing uniformity in size, shape, and tolerances, ultimately leading to reliable and expected usage.
  • Ease of Fabrication - HSS can be readily bent, formed, punched, and drilled.
  • Durability - Steel is undoubtedly one of the most durable and resilient materials. Its exceptional resistance to wear, decay, and pests makes it an ideal choice for building long-lasting structures.
  • Safety - The non-combustibility of steel makes it a safer material to use in construction, as it does not ignite or spread flames. A steel structure is also more resistant to natural disasters such as earthquakes and hurricanes.

Applications of A500 Structural Steel Tubing

ASTM A500 Structural tubing is a versatile hollow structural section (HSS) designed for load-bearing and high-strength applications across many industries. Its exceptional strength-to-weight ratio, durability, and uniformity make it suitable for a wide variety of structural tasks.

Construction & Structural Framing

Used as columns, beams, braces, and support frameworks in industrial buildings, warehouses, commercial facilities, bridges and other load-bearing infrastructure elements.

Material Handling & Storage

Supports warehouse racking systems, bulk material handling equipment, and industrial shelving due to its high strength and stability.

Automotive & Transportation

Used for vehicle frames, chassis components, commercial vehicle racks, and safety frameworks where rigidity and resilience are critical.

Architectural & Recreational Structures

Integrated into stadium supports, playground equipment, fencing systems, and renewable energy structures (e.g., solar panel and wind turbine supports).

Data Center & Industrial Equipment Frames

Structural tubing provides reliable support for server racks, cabinets, cooling towers, and other infrastructure in technology and industrial environments.

Agricultural Equipment & Infrastructure

Structural tubing supports farm machinery frames, grain systems, irrigation, livestock enclosures, and greenhouses, offering strength, durability, outdoor load capacity.

Carbon Steel Tubing

All Alliance A500 structural tubing is manufactured from durable carbon steel, engineered for consistent strength, weight, and dimensional accuracy across every load-bearing application. Our raw coil is slit on-site by our sister company Alliance Steel, ensuring tight tolerance control before it's formed into tubing. We supply this carbon steel structural tubing in Hot Rolled (HR) and Hot Rolled Pickled & Oiled (HRPO) finishes to match your project's corrosion-resistance and surface-finish requirements.

 

 

Frequently Asked Questions

ASTM A500 is a standard specification for cold-formed welded and seamless carbon steel structural tubing.

ASTM A500 covers several grades of carbon steel tubing, including Grade B, Grade C, and Grade D. Each grade has different mechanical properties and is suitable for various structural applications — see our breakdown of A500 grades and specs for guidance on selecting the right one.

The ASTM A500 specification outlines the chemical composition, tensile strength, yield strength, elongation, and other mechanical properties required for each grade of carbon steel tubing. It also includes requirements for testing, dimensions, and tolerances.

The primary applications of ASTM A500 tubing are in construction, infrastructure, and general structural purposes, where the tubing is used for supporting columns, beams, trusses, and other load-bearing structures.

 

Structural tubing (ASTM A500) is engineered for load-bearing strength in construction, agriculture, and transportation applications. Mechanical tubing (ASTM A513) prioritizes tight dimensional tolerances and surface finish for precision OEM components. Alliance Tubular Products manufactures both — choose structural tubing for strength-critical framing and mechanical tubing for precision-fit parts.

Alliance Tubular Products manufactures A500 structural tubing in square sizes from 1.5" to 5.0" (38mm to 127mm) and rectangular sizes from 1.5"x2.0" to 4.0"x6.0" (38mm to 152mm), all direct-formed Electric Resistance Welded (ERW) Hollow Structural Sections (HSS) with laser-quality corners and straightness. Lengths up to 50' are available, along with custom bundle configurations and precut lengths to match your project's exact specifications.

Painting, galvanizing, and pickling techniques can protect structural steel from corrosion.

Absolutely! Steel tubing is an excellent choice for outdoor  projects, offering several key advantages:

Exceptional Strength-to-Weight Ratio – Steel tubing delivers maximum structural support without adding unnecessary weight to your project.

Built for Durability – Unlike wood, steel won't rot, warp, or deteriorate over time, even when exposed to the elements.

Corrosion Protection – Steel tubing can be coated with protective finishes to resist rust and corrosion, ensuring long-term performance in any climate.

Low Maintenance – Once properly coated, steel tubing requires minimal upkeep while maintaining its structural integrity for decades.

Easy to Fabricate – Steel tubing's versatility makes it simple to cut, weld, and shape to meet your specific project requirements.

Whether you're building outdoor structures, frameworks, or support systems, steel tubing provides the reliability and longevity your project demands.

Short answer, yes! Steel tubing is an excellent choice for sustainable construction projects, offering environmental benefits that align with modern green building goals.

Infinitely Recyclable – Steel is 100% recyclable and can be reprocessed endlessly without any loss of strength or quality. This infinite lifecycle means today's steel tubing can become tomorrow's building materials.

Extended Building Lifespan – Steel's resistance to rotting, cracking, and pest damage ensures structures last longer, reducing the need for replacement materials and minimizing waste over time.

Recognized by Green Building Standards – Steel tubing is approved and valued by major sustainability certification programs, including:

  • LEED (Leadership in Energy and Environmental Design)
  • BREEAM (Building Research Establishment Environmental Assessment Method)

Reduced Carbon Footprint – Choosing North American-produced steel can further enhance your project's sustainability profile by minimizing transportation emissions compared to imported materials.

When you select steel tubing for your construction project, you're choosing a material that supports both structural performance and environmental responsibility.

Yes, structural tubing (HSS) is generally stronger and more rigid than open steel shapes like angle iron or channel steel of similar weight. The closed hollow geometry of HSS steel provides uniform strength in multiple directions, making it superior for resisting bending, torsion, and compression compared to traditional open steel sections.
