Product Description
High-Strength Rectangular Steel Tubes for Steel Structure Buildings
Product Overview
Our high-strength rectangular steel tubes (Rectangular Hollow Sections - RHS) are engineered specifically to provide maximum structural integrity for modern steel structure buildings, industrial warehouses, PEB (Pre-Engineered Buildings), and commercial factories. Manufactured using premium-grade steel and advanced high-frequency welding (ERW) or seamless processes, these tubes offer an outstanding strength-to-weight ratio, exceptional durability, and superior resistance to torsional loading.
We provide full customization of dimensions, wall thicknesses, lengths, and surface finishes (including pre-galvanized, hot-dip galvanized, and anti-corrosion painting) to precisely match your architectural blueprints and local building codes.

Key Product Features
- High Load-Bearing Capacity & Rigidity: Optimized for heavy-duty structural applications, allowing for longer spans and reduced overall steel consumption in industrial buildings.
- Outstanding Corrosion Resistance: Our hot-dip galvanized coating option provides up to 600g/m² of zinc protection, guaranteeing a lifespan of 20+ years in harsh tropical, coastal, or high-humidity environments.
- Engineered for Precise Fitting: Uniform thickness, tight tolerances, and perfectly de-burred square cut ends ensure smooth on-site welding or high-strength bolt connections.
- Flexible Customization (Made-to-Order): We accommodate specialized requests for chemical compositions, mechanical properties, exact cut-to-length requests, and specific bundle packing according to project blueprints.
Applications
- Industrial Infrastructure: Primary columns, roof trusses, and mezzanine beams for steel warehouses, commercial factories, and hangars.
- Prefabricated Modular Buildings: Main load-bearing wall frames and base platforms for flat-pack container houses and labor camps.
- Agricultural Frameworks: Heavy-duty structural pillars and long-span framing for commercial modern film/glass greenhouses.
Packing & Container Loading Logistics
- Seaworthy Packing: Tied firmly with heavy-duty steel strips in hexagonal bundles, wrapped with waterproof PVC woven fabric upon request to prevent salt spray corrosion during ocean transit.
- 20ft GP Container: Best suited for lengths up to 5.8m / 5.9m. Maximum loading capacity is approximately 25-28 metric tons.
- 40ft GP/HQ Container: Best suited for lengths up to 11.8m / 12.0m. Maximizes volume and weight for long structural profiles.
