Rectangular Hollow Sections

Description

1. Product Overview
Rectangular Hollow Sections (RHS) are high-strength, closed-section steel profiles engineered for structural and mechanical applications across construction and industrial sectors. Known for their uniform geometry and superior load-bearing capacity, RHS are widely used in frameworks, supports, and fabrication projects requiring strength-to-weight efficiency. Their closed shape enhances torsional rigidity and resistance to environmental stress, making them ideal for both indoor and outdoor use. Strategically, RHS are essential in modern infrastructure and manufacturing due to their versatility, cost-efficiency, and ease of fabrication.

2. Key Specifications & Technical Characteristics

• Material Composition: Carbon steel (mild steel), low-alloy steel, or galvanized steel variants
• Grade Standards: ASTM A500, EN 10219, BS 1387, JIS G3466 (depending on supply)
• Purity/Quality Level: High structural-grade steel with controlled carbon and alloy content for optimal strength and weldability
• Physical Characteristics:
  • Shape: Rectangular hollow profile
  • Surface Finish: Black, oiled, pickled, or galvanized
  • Wall Thickness: Typically 1.5 mm to 20 mm
  • Dimensions: Customizable (standard and non-standard sizes available)
  • Density: ~7.85 g/cm³
• Packaging Options: Bundled with steel straps, wrapped in waterproof material, or customized export packaging
• Shelf Life: Indefinite under proper storage conditions (dry, corrosion-protected environment)

3. Core Industrial Applications
Rectangular Hollow Sections are extensively used in construction, infrastructure, automotive, and general engineering industries. They serve as structural components in buildings, bridges, warehouses, and towers, as well as in machinery frames, transport equipment, and agricultural implements. Their flat surfaces simplify welding, cutting, and assembly, making them highly efficient for fabrication processes. Compared to open sections, RHS offer enhanced strength, better load distribution, and improved resistance to bending and torsion, resulting in longer service life and reduced maintenance costs.
