ASTM A500 Structural Steel Tube for Structural Projects
CXYS supplies ASTM A500 structural steel tube for steel fabricators, construction contractors, distributors and project buyers. The range covers round, square and rectangular hollow sections for structural frameworks and fabricated steel assemblies.
For commercial orders, we can coordinate tube dimensions, wall thickness, grade, length, surface condition and quantity according to the buyer’s specification. This makes ASTM A500 tube suitable for both regular stock purchasing and project-based procurement.
Available Tube Forms
- ASTM A500 round structural tube
- ASTM A500 square steel tube
- ASTM A500 rectangular steel tube
- Standard and project-specific lengths
- Black or specified surface condition
- Bulk quantities for export

ASTM A500 Grade Options
Different A500 grades are available for structural applications. CXYS can source according to the required mechanical and dimensional specification.
Grade B
A commonly specified option for general structural tube applications and fabricated steel structures.
Grade C
Used where the project specification calls for higher minimum yield strength than Grade B.
For a quotation, please indicate the required A500 grade, tube shape, dimensions and quantity.
Round, Square & Rectangular A500 Tube
Round Structural Tube
Round A500 tube is suitable for columns, frames, supports, barriers and other tubular structures where a circular section is preferred.
Square Structural Tube
Square tube offers four flat faces that simplify fabrication and connection work. It is commonly used for frames, supports, posts and general steel structures.
Rectangular Structural Tube
Rectangular tube provides a practical section for beams, frames and fabricated structures where different section dimensions are required.
CXYS can supply mixed shapes and sizes within a project order, subject to quantity and sourcing availability.
ASTM A500 Steel Tube Applications
Rather than being limited to one type of construction, A500 structural tubing is purchased across a wide range of fabricated steel applications.
Building Structures
Used for structural frames, columns, supports and other load-bearing steel components.
Steel Fabrication
Fabricators use square, rectangular and round tube for frames, platforms, brackets and assembled structures.
Industrial Structures
Suitable tube specifications can be sourced for equipment supports, walkways, racks and plant structures.
Infrastructure & General Construction
A500 tube is also used in fencing systems, barriers, transportation structures and other fabricated steelwork.
A500 Tube Size & Supply Options
Project buyers usually specify A500 tube by shape + outside dimensions + wall thickness + length + grade.
CXYS can work from either a detailed specification or a simple purchasing list.
For example:
Rectangular Tube → 200 × 100 mm → 8 mm WT → Grade B → 12 m → Required Quantity
If you have multiple sizes, sending the complete size list allows us to review the requirement as one order.
Surface & Processing Options
The standard supply condition can be adjusted to the intended fabrication process.
Available requirements may include:
- Black mill finish
- Cut-to-length
- Plain ends
- Bundling by size
- Customer marking
- Specified surface treatment
Additional fabrication or surface requirements should be included in the RFQ so they can be considered together with the material specification.
ASTM A500 Structural Tube Supply for Export
CXYS works with international buyers who need dependable sourcing rather than a single fixed tube product.
Our supply service is designed for:
- Steel distributors
- Structural steel suppliers
- Construction contractors
- Fabrication companies
- EPC procurement teams
- Project material buyers
For larger orders, we can coordinate multiple A500 tube sizes, grades and shapes within the same purchasing program where supply conditions allow.
Packing & Delivery
A500 structural tubes are generally supplied in bundles for easier handling, storage and transportation. Bundle identification can be arranged according to size, grade and order requirements.
For export shipments, CXYS coordinates:
- Bundle packing
- Steel-strip securing
- Product marking
- Quantity and weight checking
- Container loading
- Port shipment arrangements
The recommended shipping method depends on tube dimensions, order volume and destination.
ASTM A500 Chemical Composition
Chemical requirements vary by grade and product form under ASTM A500/A500M. For procurement, the applicable grade should be confirmed first rather than applying one composition to all A500 tubes.
| Element | Typical Requirement |
|---|---|
| Carbon (C) | Grade-dependent |
| Manganese (Mn) | Grade-dependent |
| Phosphorus (P) | Controlled |
| Sulfur (S) | Controlled |
| Copper (Cu) | When specified |
The final chemical requirements should be checked against the applicable ASTM edition and ordered grade.
ASTM A500 Mechanical Properties
| Grade | Minimum Yield Strength | Minimum Tensile Strength |
|---|---|---|
| Grade B | 46 ksi (315 MPa) | 58 ksi (400 MPa) |
| Grade C | 50 ksi (345 MPa) | 62 ksi (425 MPa) |
Values can vary by product shape and applicable ASTM requirements. The purchase specification should be used as the controlling reference.
FAQ
What is ASTM A500 structural steel tube?
ASTM A500/A500M is a specification covering cold-formed welded and seamless carbon steel structural tubing in round, square and rectangular shapes.
What shapes are available?
The main forms are round, square and rectangular structural tubes.
What is the difference between A500 Grade B and Grade C?
Grade C has higher minimum specified yield and tensile strengths than Grade B, making it an option where the project design requires higher strength.
Can you supply A500 square and rectangular tube?
Yes. CXYS can coordinate both square and rectangular A500 structural tubing, along with round tube according to the required specification.
Can I buy ASTM A500 tube in bulk?
Yes. Bulk orders can be arranged for distributors, fabricators, contractors and structural steel projects.
