Product Name: Structural Rectangular Steel Tube
Introduction
Structural Rectangular Steel Tube is a hollow section with differing height and width dimensions, formed by cold‑rolling and welding (ERW) or seamless piercing. Its geometry offers tailored flexural properties-higher stiffness in one axis and efficient load distribution-making it ideal for beams, columns, and frames in construction and industrial applications. With uniform wall thickness and smooth external surfaces, rectangular tubes provide clean lines, easy detailing, and versatile connection options.

Features & Advantages
Directional Strength: Rectangular profile delivers higher moment of inertia about one axis-ideal for beams and columns where orientation matters.
Efficient Material Use: Optimized geometry reduces weight while meeting targeted bending and compression requirements.
Flat Surfaces: Smooth faces simplify attachment of gussets, brackets, and cladding without additional reinforcement.
Versatile Finishes: Available in bare, primed, hot‑dip galvanized, or powder‑coated for corrosion protection and aesthetics.
Cost‑Effective Production: ERW process ensures competitive pricing; seamless options for high‑pressure or critical applications.
Applications
Building Frames: Beams, purlins, and columns in steel structures.
Industrial Racking & Shelving: Uprights and cross‑members in warehouse systems.
Machine Guards & Enclosures: Protective panels and frames for equipment.
Furniture & Architectural Features: Table frames, handrails, and decorative façades.
Automotive & Transport: Trailer chassis rails, forklift masts, and support brackets.
Packaging & Delivery
Bundling: Tubes grouped by dimension and length, strapped securely with steel bands, and supported on treated skids.
End Protection: Plastic or metal caps to prevent ingress and protect tube ends.
Surface Protection: Optional oiling or primer for indoor storage; galvanized finish for outdoor exposure.
Lead Time: Standard production and shipment within 15–25 days after order confirmation; expedited schedules (10–15 days) available.
