FAQ – Everything You Need to Know About Steel Round Tubes
A steel round tube is a hollow circular metal profile used in a wide range of structural, industrial, and fabrication applications. Thanks to its excellent strength-to-weight ratio, it provides a strong and durable solution while being lighter than a solid bar of equivalent diameter.
Steel round tubes are widely used in the manufacturing of metal structures, machinery, frames, guardrails, mechanical supports, and many other components requiring strength, durability, and versatility.
When referring to steel products, HSS generally stands for Hollow Structural Section. This term describes a family of hollow steel sections primarily designed for structural applications and steel fabrication.
Thanks to their hollow design, HSS tubes offer an excellent strength-to-weight ratio, good rigidity, and great versatility for projects requiring strong and durable structures.
At Groupe David, steel round tubes are available in several types and specifications to meet different fabrication needs and mechanical performance requirements.
A500
- Structural steel commonly used for HSS applications
- Excellent mechanical strength
- Widely used for load-bearing structures
- Good weldability
A513
- Precision mechanical tubing
- Tighter dimensional tolerances
- Good surface quality
- Ideal for mechanical components and applications requiring high precision
HRPO (Hot Rolled Pickled & Oiled)
- Hot rolled steel that has been pickled and oiled
- Cleaner, descaled surface compared to standard hot rolled steel products
- Good suitability for welding and fabrication processes
C.R. (Cold Rolled)
- Cold rolled steel
- Smoother and more uniform surface finish
- Improved dimensional accuracy
- Recommended for applications requiring a higher-quality finish
The choice of tube mainly depends on the required mechanical properties, level of precision, and intended application.
At Groupe David, steel round tubes are available with the following specifications:
- Standard lengths: between 20 and 24 feet (≈ 6.1 to 7.3 metres)
- Multiple diameters and wall thicknesses are available to meet the needs of various structural and industrial projects.
For more details, please refer to our product catalogue.
Custom cutting services are also available according to your project requirements.
Steel round tubes are used in a wide range of industrial, commercial, and manufacturing applications, including:
- Metal structures
- Machinery fabrication
- Equipment frames and chassis
- Guardrails and handrails
- Fencing
- Industrial supports
- Agricultural equipment
- Trailers
- Custom fabrication projects
- Steel furniture
Their strength, rigidity, and versatility make them a preferred choice for many fabrication and construction projects.
The selection depends on several criteria.
Application type
- Metal structures
- Mechanical fabrication
- Metal furniture
- Industrial equipment
- Architectural projects
Tube type or specification
- A500 for structural applications
- A513 for mechanical applications requiring greater precision
- HRPO when a descaled surface improves welding, painting, or fabrication operations
- C.R. (Cold Rolled) when tighter tolerances and improved surface finish are required
