Square pipes are widely used across construction, fabrication, engineering, and industrial frameworks due to their uniform shape, high strength, and aesthetic appeal. Their versatility makes them suitable for everything from lightweight furniture to heavy structural projects. Whether you are a contractor, manufacturer, or steel buyer, understanding square pipe sizes, weight calculations, and price comparisons helps you make informed decisions and optimize costs. This guide covers all essential details for anyone purchasing square hollow sections (SHS).

Square Pipe Sizes – Common Dimensions

Square pipes are available in a variety of sizes and thicknesses to meet the needs of different industries. The most common dimensions include:
• Size Range: 12x12 mm to 250x250 mm
• Wall Thickness: 0.8 mm to 10 mm
• Length: Standard 20 feet or 6 meters
• Finish Options: MS, galvanized, stainless steel, or powder-coated
Larger square pipes offer higher load-bearing capacity, while smaller sizes are preferred for lightweight fabrication and design projects.

Square Pipe Weight Chart (General Reference)

Weight varies based on size, thickness, and manufacturing standards. Here is a general weight reference for commonly used square pipes (per meter):
• 20×20×1.2 mm: Approx. 0.7 kg per meter
• 25×25×2.0 mm: Approx. 1.5 kg per meter
• 40×40×2.0 mm: Approx. 2.35 kg per meter
• 50×50×2.5 mm: Approx. 3.75 kg per meter
• 75×75×3.0 mm: Approx. 6.70 kg per meter
• 100×100×4.0 mm: Approx. 12.0 kg per meter
Exact weight may vary slightly between manufacturers, but most suppliers follow standard IS 4923 (YST 210/310/355) for structural hollow sections.

Applications of Square Pipes

Square pipes are chosen for their strength, clean edges, and ability to handle uniform load distribution. Some popular uses include:
• Construction & Structural Support: Columns, beams, trusses, and structural frameworks
• Fabrication & Engineering: Industrial machinery, plant structures, machine frames
• Furniture & Interior Design: Tables, chairs, partitions, and decorative frameworks
• Automotive & Transport: Bus body parts, support frames, copyright structures
• Fencing & Gates: Durable frames for residential and commercial spaces
• Solar Structures: Solar mounting frames and support systems
• General Fabrication: Racks, storage units, and customized metal projects
Their robust design and square geometry make them ideal for both load-bearing and aesthetic applications.

Price Comparison – What Affects Square Pipe Rates?

Square pipe prices depend on several market and production factors. Key elements influencing cost include:
• Size & Thickness: Larger dimensions and higher thickness increase weight and cost.
• Material Type: MS square pipes are economical, while SS and GI variants cost more.
• Raw Material Fluctuations: Changes in steel and scrap prices affect daily rates.
• Brand & Certification: IS-certified manufacturers may charge slightly higher for quality assurance.
• Quantity Purchased: Bulk buyers usually get better pricing and discounts.
Generally, MS square pipe prices range from budget-friendly small sections to higher-cost large structural sections used in heavy construction.

Conclusion

Square pipes offer an excellent combination of strength, versatility, and cost-effectiveness, making them one of the most widely used steel sections across industries. Understanding their sizes, weight chart, applications, and price variations helps buyers choose the right material and get the best value for their requirements.
