Square Pipe SHS
structural square pipes and Square Hollow Sections (SHS) engineered for heavy-duty infrastructure staging, commercial building frameworks, automated equipment chassis, and high-load civil engineering modules. We guarantee exceptional corner radius structural distribution, absolute weld-seam integrity, and strict dimensional concentricity under our direct [2-Hour Rapid Quote] mill program.
Tired of slow supplier responses while your critical project bidding deadline closes in? Terrified of receiving out-of-square hollow sections that warp during welding, split at corner radii, or fail strict structural building inspections? Eliminate cross-border purchasing risks and secure your mill-verified testing logs immediately.

Technical QA/QC Verification
• Uncompromised EN 10204 3.1 Traceability: Every batch is accompanied by genuine Mill Test Certificates detailing comprehensive mechanical testing—including charpy v-notch impact trials, flatten parameters, yield and elongation capacity maps—fully aligned with target civil frameworks. Fully prepared for third-party engineering audits by SGS, BV, or TÜV.
• Capital Security Guarantee: We remove international transactional friction for structural contractors and global purchasing portals by approving large-scale volume shipments under 100% Irrevocable Letters of Credit (L/C) at sight financial architectures.
Structural Protection & Ocean Logistics
• Rigid Maritime Dunnage & Container Lashing: Structural pipe components are separated by thick timber spacers and braced with heavy-gauge cross-bracing wedges. Cargo is cross-anchored inside marine containers via industrial steel wire tie-downs and heavy web strapping to block lateral shifted forces over rough sea channels.
• Complimentary Extended Destination Port Demurrage: SXY Steel Group natively provides an extended allocation of 14 to 21 days of container demurrage directly at your target port of discharge, providing your broker teams with ample buffer windows to process customs clearing protocols.
Square tube is formed from coil and then ran through a series of dies. It’s welded from the inside to form its shape. Square tubes are generally used for maintenance and structural purposes.
Some examples of square tubing applications would be building construction, railings, and sign posts. They are measured by their outside dimensions and their wall thickness.
Square Tube is available in the following metal types:
Alloy Steel
Mild Stee
Carbon Steel
Stainless Steel
Square tube has similar uses to RHS and is used for both industrial and construction applications. Square section RHS is available in the same thicknesses as RHS and dimensions range from 20 mm x 20 mm to 400 mm x 400 mm.

Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
Factory workshop
With a commitment to excellence, innovation, and sustainability, the company has established itself as a trusted partner in the international steel industry.After nearly two decades of relentless endeavour, our client base now spans over 110 countries and regions across Europe, the Middle East, South America, and Southeast Asia.
