Hollow Section Weight Chart — RHS, SHS & CHS
This hollow section weight chart — rhs, shs & chs provides accurate weight data for engineers, procurement teams, and fabricators. Whether you are preparing a Material Take-Off (MTO), verifying supplier invoices, or estimating transport costs, this reference chart gives you the per-metre and per-foot weights for all standard sizes. Creative Metal Industries, Vadodara stocks all listed sizes — call +91 99982 80619 for availability and pricing.
Weight Calculation Formula
The weight of any hollow pipe/tube is calculated using the formula: Weight (kg/m) = (OD - WT) × WT × 0.02466 × Density Factor. Where OD = Outside Diameter in mm, WT = Wall Thickness in mm. The density factor varies by material: Carbon Steel = 1.000 (7.85 g/cm³), Stainless Steel 304/316 = 1.020 (8.00 g/cm³), Duplex 2205 = 0.994 (7.80 g/cm³), Inconel 625 = 1.078 (8.44 g/cm³), Monel 400 = 1.130 (8.83 g/cm³), Titanium Gr.2 = 0.574 (4.51 g/cm³), Copper Nickel 70/30 = 1.129 (8.86 g/cm³).
For solid bars: Weight (kg/m) = D² × 0.006165 × Density Factor (where D = diameter in mm). For flat bars: Weight (kg/m) = Width × Thickness × 0.00785 × Density Factor. For plates/sheets: Weight (kg) = Length × Width × Thickness × 7.85 / 1000000 (for CS/MS). Always verify calculated weights against actual mill weights as manufacturing tolerances (typically ±10-12.5% on wall thickness per ASTM standards) create minor deviations.
Standard Sizes & Weight Per Metre
The chart below covers the most commonly specified sizes in the Indian market. All weights are theoretical (calculated) based on nominal dimensions. Actual weights may vary within ASTM/IS standard tolerances. For pipes, NB (Nominal Bore) sizes from 1/2 inch to 24 inch are covered across schedules 5S, 10S, 40/40S, 80/80S, 120, 160, and XXS. For structural sections, all standard IS 808 designations are included.
Creative Metal Industries maintains ready stock of the most demanded sizes highlighted in the chart. For non-standard sizes, we source from approved mills within 2-4 weeks. Minimum order quantities vary by product — standard sizes typically have no MOQ from stock, while indent orders may require mill-minimum quantities. Contact us for specific availability.
How to Use This Chart for MTO
When preparing a Material Take-Off (MTO) for a piping project, multiply the weight per metre by the total length required for each size/schedule combination. Add 5-10% wastage allowance for cutting, bevelling, and fitup. For fittings, use the individual piece weight from the fittings weight chart. For flanges, refer to the flange weight chart by class and size. This gives you the total tonnage requirement for transport planning and cost estimation.
Pro tip: When comparing quotations from different suppliers, always verify that the weight basis matches — some suppliers quote on theoretical weight while others quote on actual (weighed) weight. ASTM standards allow ±10% tolerance on wall thickness, which means actual weight can deviate from theoretical by 5-8%. At CMI, we supply on actual weight basis with weighbridge tickets provided for bulk orders.

Frequently Asked Questions
How accurate is this weight chart?
This chart shows theoretical (calculated) weights based on nominal dimensions. Actual weights may vary within standard manufacturing tolerances (typically ±10-12.5% on wall thickness per ASTM standards). For commercial transactions, CMI supplies on actual weighed weight with weighbridge tickets for bulk orders.
What density value is used for stainless steel?
Stainless steel 304/316 density is 8.00 g/cm³ (versus 7.85 for carbon steel). This means SS pipe weighs approximately 2% more than equivalent CS pipe of the same dimensions. For duplex 2205, density is 7.80 g/cm³ (slightly lighter than CS). Exotic alloys vary: Inconel 625 = 8.44, Monel 400 = 8.83, Titanium = 4.51 g/cm³.
How do I calculate pipe weight for my MTO?
Use formula: Weight (kg/m) = (OD - WT) x WT x 0.02466 x density factor. Multiply by total length required. Add 5-10% wastage for cutting and fitup. For quick reference, use this chart or contact CMI at +91 99982 80619 for assistance with MTO estimation.
Does CMI supply all sizes shown in this chart?
Yes, Creative Metal Industries stocks most standard sizes from this chart for immediate dispatch. Non-standard sizes can be arranged on indent within 2-4 weeks. Call +91 99982 80619 for specific size availability — we maintain real-time inventory tracking.
