Hollow Sections

As a leading specialized manufacturer, FOREVER STEEL provides high-precision Carbon Steel Hollow Sections, including Square (SHS), Rectangular (RHS), and Circular (CHS) profiles. Engineered for superior load-bearing capacity and structural efficiency, our hollow sections are the preferred choice for modern architecture, industrial frameworks, and heavy machinery manufacturing.

We utilize advanced cold-forming and high-frequency welding technologies to produce a wide array of profiles:

Square Hollow Sections (SHS): 20mm x 20mm–600mm x 600mm

Rectangular Hollow Sections (RHS): 20mm x 30mm–400mm x 600mm

Circular Hollow Sections (CHS): 21.3mm–1219mm (O.D.)

Wall Thickness (W.T.): 1.2mm–50mm (Tailored to specific structural load requirements).

Our production strictly adheres to international structural benchmarks, ensuring safety and global project compatibility:

European Standards: EN 10210 (Hot finished), EN 10219 (Cold formed).

American Standards: ASTM A500 Grade A/B/C/D, ASTM A501, ASTM A1085.

Australian Standards: AS/NZS 1163 (C250, C350, C450).

Japanese/Chinese Standards: JIS G3466, GB/T 6728, GB/T 3094.

Steel Grades: S235JR, S275J0H, S355J2H, S355K2H, Q235, Q355.

To facilitate seamless on-site assembly and long-term durability:

End Finishing: * Square Cut: Precise 90°cut with professional deburring for modular construction.

Bevelled Ends: Available for thick-walled sections to ensure deep weld penetration.

Surface Protection: * Standard: Light oiling or black varnish for temporary protection.

High Durability: Hot-Dipped Galvanized (HDG) per EN ISO 1461, providing superior atmospheric corrosion resistance.

Pre-Coating: Shop primer (Red/Grey) or powder coating for aesthetic architectural applications.

Our hollow sections provide the backbone for diverse engineering sectors:

Civil Engineering: Large-span airport terminals, sports stadiums, and high-rise curtain walls.

Infrastructure: Bridge trusses, highway signage supports, and transmission towers.

Machinery Manufacturing: Crane booms, agricultural equipment frames, and automotive chassis.

Solar Energy: Structural mounting systems for large-scale solar farms.

Technical Precision: Strict monitoring of corner radii, twist, and straightness to ensure compatibility with automated laser-cutting systems.

Structural Testing: Non-destructive testing (NDT), flattening tests, and Charpy V-notch impact testing for low-temperature applications.

Certification: Mill Test Certificates (MTC) issued per EN 10204 3.1.

Third-Party Verification: Full cooperation with SGS, BV, or TUV for material verification and dimensional audit.

We prioritize the arrival of your structural components in "Ready-to-Install" condition:

Packaging: * Hexagonal bundles secured with high-tensile steel straps for safe crane handling.

Protective plastic or woven wrapping for galvanized surfaces to prevent "White Rust."

Logistics Security: * Sea-worthy lashing and timber dunnage to prevent shifting in bulk vessels or containers.

Clearly stenciled Heat No., Size, Grade, and Project ID on each bundle for site-side traceability.

Handling: Use of nylon slings to maintain the integrity of the surface finish.
