MS Rectangular Pipes in Structural Steel: Strength, Versatility & Applications

Mild Steel (MS) Rectangular Pipes — also called Rectangular Hollow Sections (RHS) — are among the most widely used structural steel products in construction, infrastructure, and fabrication. Known for their strength, dimensional stability, and cost-effectiveness, MS rectangular pipes are used in everything from building frameworks and bridges to furniture and automotive frames.

At Heybuildex, we supply high-quality MS rectangular pipes sourced directly from trusted manufacturers. Below is a complete guide covering properties, types, sizes, applications, buying tips, and why RHS is a smart choice for modern projects.

Key Highlights of MS Rectangular Pipes

• Material Strength: Made from mild steel for excellent toughness and load-bearing capacity.
• Versatility: Suitable for structural, fabrication, automotive, furniture, and infrastructure uses.
• Multiple Sizes & Thicknesses: Wide range to suit both light and heavy-duty applications.
• Fabrication Friendly: Easy to cut, weld, bend and finish.
• Cost-Effective: More affordable than stainless steel alternatives while delivering dependable performance.

What are MS Rectangular Pipes?

MS Rectangular Pipes (RHS) are hollow steel sections with a rectangular cross-section. They combine good surface coverage with balanced structural performance, making them ideal where flat surfaces or rectangular frames are required. RHS is available in ERW (Electric Resistance Welded) and seamless forms, and produced by hot-rolling or cold-rolling depending on the required finish and strength.

Properties of MS Rectangular Pipes

• High mechanical strength: Suitable for heavy-load structural applications.
• Dimensional accuracy: Uniform wall thickness and precise sizing for predictable performance.
• Workability: Simple to cut, weld and machine on-site or in workshops.
• Corrosion resistance: Performs well when galvanized or painted for outdoor use.
• Thermal stability: Withstands typical temperature ranges in industrial settings.

Types of MS Rectangular Pipes

• ERW Rectangular Pipes: Cost-effective and commonly used for general structural needs.
• Seamless Rectangular Pipes: Higher strength and pressure resistance for demanding applications.
• Hot Rolled RHS: Robust sections for heavy construction work.
• Cold Rolled RHS: Smooth finish for furniture, fittings, and aesthetic applications.

Common Sizes & Dimensions

• Thickness: Typically 1 mm to 12 mm.
• Width × Height: Examples — 20×40 mm, 40×80 mm, 50×100 mm, 100×200 mm, etc.
• Length: Standard 6 meters; custom cuts available as per project needs.

Applications of MS Rectangular Pipes

1. Construction:
   • Structural frames, columns, beams, and supports for buildings and bridges.
   • Architectural elements where straight, flat surfaces are needed.
2. Automotive & Transport:
   • Chassis components, trailers, bus bodies, and agricultural machinery frames.
3. Furniture:
   • Office furniture, racks, storage systems, and decorative frames.
4. Fabrication & Engineering:
   • Industrial sheds, machine frames, conveyors and custom fabrication works.
5. Infrastructure:
   • Railway platforms, metro stations, airport structures, and public infrastructure.
6. Agriculture & Irrigation:
   • Greenhouse frames, fencing, and outdoor structures requiring durability.

Advantages of Using MS Rectangular Pipes

• Excellent strength-to-weight ratio for efficient structural design.
• Cost-efficient compared to higher-grade alloy steels.
• Uniform strength distribution—rectangular cross-section reduces bending stresses in certain orientations.
• Lightweight and easy to transport and install.
• Recyclable—supports sustainable construction practices.

Buying Tips

• Choose the right type: ERW for general use; seamless for high-pressure or heavy-duty needs.
• Check thickness & section size: Match to engineer’s specifications to avoid over- or under-design.
• Inspect coatings: For outdoor use prefer galvanized or painted finishes to prevent corrosion.
• Verify standards: Ensure compliance with IS/ASTM/EN specs as required (e.g., IS 4923 where applicable).
• Order custom lengths: Reduce waste by specifying cut-lengths for your project.
