* MSG = Manufacturer's Standard Gauge — US origin, based on weight per square foot at specific steel density. Commonly used in North American SS sheet specifications and sometimes in imported coil data for India. Not equivalent to SWG or BWG — always cross-check with mm value when converting US drawings to Indian market specifications.

* Weight per sheet based on standard 2500×1250 mm size (3.125 m²). Formula: kg/m² = Thickness (mm) × Density (g/cm³). Per sheet weight = kg/m² × 3.125 m². For other sheet sizes or circular blanks, use our Steel Sheet Weight Calculator. SS 316 is heavier than SS 304 at the same gauge due to higher molybdenum content increasing density to 7.98 g/cm³.

Surface finish does not affect gauge number, thickness or weight. Finish only affects surface appearance and cost. BA and 8K finishes carry 20–40% price premium over standard 2B. Source: IS 6911:1992 and Euro Inox Surface Finish Guide.
Simple guide for Indian engineers, fabricators and procurement teams
Confirm whether your drawing or supplier uses SWG (most common in India), BWG (older British drawings) or MSG (US/imported specs). The same gauge number gives very different thicknesses across standards — e.g., 14 SWG = 2.032 mm, 14 BWG = 2.108 mm, 14 MSG = 1.897 mm.
Enter your gauge standard and gauge number in the Quick Lookup box at the top of this page. Get instant thickness in mm and inch plus weight per m² for SS 304, SS 316 and SS 202 without scrolling through the full chart.
Use the search box above each chart to filter by gauge number or type a thickness value to find the nearest gauge. Click any column header to sort ascending or descending. Use the thickness range filter to show only thin, light, medium or heavy gauges.
Weight per m² = Thickness (mm) × Density (g/cm³). For SS 304 at 1.626 mm (16 SWG): 1.626 × 7.93 = 12.89 kg/m². Multiply by your sheet area in m² to get weight per sheet. Use the Weight by Grade tab for pre-calculated standard sheet weights.
Once you have kg per sheet from the chart, multiply by quantity for total kg and divide by 1000 for metric tonnes (MT). For exact calculation with custom sheet sizes, circular blanks or any quantity, use our Steel Sheet Weight Calculator.
For IS 6911 certified SS sheets, always verify gauge and actual thickness from the Mill Test Certificate (MTC). IS 6911 allows thickness tolerance of −0.04 mm to +0.10 mm for sheets under 1.6 mm. Actual weight may vary up to ±4% from nominal gauge weight.
Best practices from Indian SS fabricators, kitchen equipment manufacturers and architectural metalwork contractors
The most common SS procurement error in India is mixing gauge standards on the same project. Always specify millimetres (mm) on your purchase order to completely avoid gauge ambiguity. Write: "SS 304 2B, 1.626 mm (16 SWG)" — never just "16 gauge SS". This eliminates the SWG vs BWG confusion that costs fabricators money every year.
Indian commercial kitchen equipment standards (FSSAI and NSF equivalent) typically specify: worktops 16G SWG (1.626 mm) SS 304, sinks 18G SWG (1.219 mm) SS 304, storage racks 18G SWG SS 304, heavy duty prep tables 14G SWG (2.032 mm) SS 304. Never substitute SS 202 for SS 304 in food-contact surfaces — FSSAI audits flag this as a hygiene risk.
Standard Indian architectural SS cladding practice: façade panels minimum 1.5 mm (≈ 16G SWG) with backing, lift interiors 1.0–1.2 mm SS 304 HL or No.4, balustrade infill panels 1.5–2.0 mm SS 316 (coastal), signage letters 1.5–2.0 mm. Thinner than 1.0 mm requires a backing framework for rigidity and is prone to oil-canning on large flat areas.
Approximate ex-Mumbai stockist prices April 2026: SS 304 2B 1.0–3.0 mm: ₹2,00,000–₹2,30,000/MT; SS 316 2B: ₹2,90,000–₹3,30,000/MT; SS 202 2B: ₹1,20,000–₹1,45,000/MT; SS 304 No.4 carry 15–20% premium over 2B; SS 304 8K mirror carry 30–40% premium. Prices change weekly with LME nickel — always confirm current rates with Jindal Stainless, Chromeni or local stockist.
SS 304 requires larger bend radii than MS due to its higher work hardening rate. Approximate minimum inside bend radius: up to 16G SWG = 1×t; 14G–12G = 1.5×t; 10G and above = 2×t (where t = thickness). Across the grain direction requires 20–30% larger radius than along the grain. Incorrect bend radius causes cracking especially in heavy gauges — always trial bend before production runs.
For SS 304 and SS 316 projects, order 5–8% surplus above net weight for cutting losses, trial pieces and storage scrap. SS offcuts have high scrap value (≈ ₹80–100/kg for SS 304 scrap in 2026) — always segregate SS scrap from MS. Store SS sheets on wooden dunnage — never on bare MS racks which cause iron contamination, leading to rust staining on the SS surface that is difficult to remove.
