Typical Applications

Where structural hollow sections are used

Steel structuresBuilding columns, roof trusses, bracing, portal frames, mezzanines and industrial structures.

Fabrication workEquipment bases, frames, racks, supports, guardrails, trailers and modular steel assemblies.

Infrastructure projectsStation work, bridges, public facilities and outdoor structures where hollow section weight and stiffness are useful.

Standard selection note

Use EN 10219 for cold formed welded hollow sections and EN 10210 when the project specifies hot finished structural hollow sections.

Quotation note

Provide drawings or a tube list when corner radius, tolerance, galvanizing thickness, cut length or third-party inspection is controlled by the project.

Buyer FAQ

Questions to settle before quotation

What is included in structural hollow section supply?

Structural hollow section supply normally covers SHS, RHS and CHS. The RFQ should identify shape, outside dimensions, wall thickness, length, grade, standard, surface and certificate requirement.

When should EN 10219 or EN 10210 be used?

EN 10219 is commonly used for cold formed welded structural hollow sections, while EN 10210 is used for hot finished structural hollow sections. Final selection follows the project specification.

What ASTM grades are common for structural tube?

ASTM A500 Grade B and Grade C are common RFQ references. ASTM A1085 may be specified when the project requires tighter structural tube controls.

What details are needed for quotation?

Provide shape, size, wall thickness, length, grade, standard, black or galvanized surface, quantity, bundle packing, inspection level, MTC and destination port.
