Thin Wall 304 Stainless Steel Square Tube with 0.5mm-3mm Wall Thickness for Lightweight Structural Applications
- Weight Reduction 40-70%: Dramatically reduces tube weight compared to standard-wall structural tubing, lowering material cost per meter, shipping charges, and handling effort.
- Cost-Effective Material Usage: Optimized thin wall design delivers required structural performance while minimizing stainless steel consumption.
- Square Profile Torsional Rigidity: Square cross-section provides higher torsional stiffness than round tube of equivalent area, resisting twisting under asymmetrical loading.
- Precision Roll Forming: Advanced multi-stage roll forming ensures consistent corner radii and wall thickness within close tolerances.
- Uniform Satin Surface Finish: Satin/320 grit polished surface provides clean, professional appearance with consistent grain direction.
- Easy Fabrication: Can be cut, drilled, welded, and formed using standard metalworking tools with TIG welding for clean, minimal-distortion joints.

Thin wall 304 stainless steel square tubes are essential in contemporary furniture design, combining lightweight construction, modern aesthetics, and corrosion resistance. Applications include:
Office Furniture: Desk frames, pedestal legs, monitor stand supports, and cable management channels in workstation systems.
Retail Display: Structural framework for clothing display rails, merchandise shelving, gondola systems, and point-of-purchase displays.
Exhibition & Trade Shows: Modular booth frameworks, graphic panel supports, lighting truss components, and information desk frames.
Hospitality Furniture: Table bases, bar stool frames, room dividers, and outdoor patio furniture under covered conditions.
Architectural Metalwork: Lightweight balustrade infill bars, decorative screening panels, sun shading louver frames, and suspended ceiling grids.
Each tube is individually wrapped in PE film and bundled with cardboard interleaving separators. Bundles are secured with non-metallic strapping and packed in ISPM 15 compliant plywood cases. Every shipment includes EN 10204 3.1 material certification with chemical composition, mechanical properties, and dimensional reports.
Our ISO 9001:2015 certified quality system ensures consistent product quality through in-line dimensional monitoring, visual weld inspection, and surface finish verification. Standard stock sizes ship within 5 working days; custom requirements are fulfilled within 15-25 working days.
Value-added services include precision cut-to-length, end deburring, and pre-drilling for assembly hardware, delivering ready-to-assemble tube kits directly to manufacturing facilities.
