Square Steel Tube (SHS)
Square hollow sections for columns, frames, supports and fabricated structural assemblies. Specify outside dimensions, wall thickness, length and grade.
Global Steel Supply & Processing
SHS & RHS · ASTM A500 · ASTM A1085 · EN 10219
Select the section shape and provide the dimensions required by your structural drawings.
Square hollow sections for columns, frames, supports and fabricated structural assemblies. Specify outside dimensions, wall thickness, length and grade.
Rectangular hollow sections for beams, trusses, equipment frames and architectural steelwork. Send the long side, short side, wall thickness and required length.
Your RFQ should identify the hollow-section standard, dimensions, grade, manufacturing route and inspection requirements.

Choose the standard and grade named in your structural design documents. Grade names and mechanical requirements are tied to their own product standards.
| Standard | Example grade / designation | Product scope |
|---|---|---|
| ASTM A500/A500M | Grade B / Grade C | Cold-formed welded and seamless carbon steel structural tubing |
| ASTM A1085/A1085M | HSS to A1085 requirements | Structural hollow sections with defined material and dimensional requirements |
| EN 10219-1 / -2 | S235JRH, S275J0H, S355J2H | Cold-formed welded structural hollow sections |
| EN 10210-1 / -2 | S235JRH, S275J0H, S355J2H | Hot-finished structural hollow sections |
ASTM and EN grade designations are not automatic equivalents. Confirm chemistry, mechanical properties, impact requirements, dimensional tolerances and delivery condition against the ordered standard.
Hollow-section dimensions affect connection detailing, section properties and fabrication. Use the exact standard dimension table or approved drawing for the ordered section.
SHS and RHS sections are used across structural fabrication, building systems and industrial equipment frames.
Columns, beams, bracing and secondary structural members.
Portal-frame components, supports and roof structures.
Structural members and fabricated supports according to engineering specifications.
Load-bearing bases, machine frames and protective structures.
Canopies, façades, balustrade frames and visible structural assemblies.
Chassis elements, trailers and fabricated support structures.
Your order is supported by company-wide steel production, inventory operations and export coordination.
Actual annual steel production across the company’s steel product range.
Company-wide steel inventory; SHS/RHS grade, size and finish availability is confirmed per enquiry.
Confirm section dimensions, grade, standard, tolerances and inspection documents with your order.
Arrange bundle quantities, protection, loading details and destination requirements in the quotation.
Send your size schedule, wall thickness, grade, length and total tonnage. Our team will confirm the applicable supply route, order quantity and shipment schedule.
Define the certificate, heat identification, outside dimensions, wall thickness, straightness and weld inspection requirements in your order documents.
Specify cut lengths, end preparation, holes or drawings when you request a quotation.
Fixed lengths based on your cutting list and order tolerances.
Hole positions and diameters based on approved drawings.
End cuts and preparation details confirmed for the required connection.
Attach your tube schedule and fabrication drawings for a combined material quotation.
Use outside dimensions, wall thickness, length and quantity for an indicative carbon steel mass estimate.
Simplified sharp-corner estimate for enquiry planning. Actual section mass depends on corner radii, wall tolerance and product standard. Use certified section tables for design.
Provide exact dimensions and standard for your project quotation.
Specify bundle lengths, surface protection, marking, container loading and destination requirements for your shipment.
Connect your square and rectangular tube order with other steel product requirements.
Provide section shape, outside dimensions, wall thickness, length, grade, manufacturing standard, quantity and destination.
Common specifications include ASTM A500/A500M and A1085/A1085M, plus EN 10219 for cold-formed welded sections and EN 10210 for hot-finished sections.
They have different manufacturing routes and may have different corner radii and section properties. Confirm the specified product standard and design data before substitution.
Include your cut-length schedule, drawings, hole positions and tolerance requirements in the enquiry for confirmation.
Send your required grade, dimensions, quantity and destination. Our team will review the inquiry.
