What is GI Sheet? (GI Sheet Full Form and Meaning)
GI Sheet full form is Galvanized Iron Sheet. It is a flat cold-rolled steel sheet coated with a uniform layer of zinc through a hot-dip galvanizing process — the steel is passed through a bath of molten zinc at approximately 450°C. The zinc coating bonds metallurgically to the steel surface, creating a barrier that prevents rust and oxidation. GI Sheet is also called GP Sheet (Galvanized Plain Sheet) in the Indian market. Both terms refer to the same product — a zinc-coated flat steel sheet manufactured as per IS 277. GI Sheet differs from GI Coil only in form: sheets are cut to fixed dimensions (8x4, 8x3, 6x3 feet) while coils are continuous rolls fed into press machines.
GI Sheet Weight Calculator
To calculate GI sheet weight: Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 7.85. Example: 8x4 ft sheet (2.438m × 1.219m) at 0.5mm thickness = 2.438 × 1.219 × 0.5 × 7.85 = 11.66 kg. Note: zinc coating adds approximately 0.8–2.2 kg per tonne to total weight depending on coating grade.
| Thickness | Weight (KG) | Weight (LBS) |
|---|---|---|
| 0.30mm | 6.99 | 15.41 |
| 0.40mm | 9.32 | 20.55 |
| 0.50mm | 11.65 | 25.68 |
| 0.60mm | 13.98 | 30.82 |
| 0.80mm | 18.64 | 41.10 |
| 1.00mm | 23.30 | 51.37 |
| 1.20mm | 27.96 | 61.64 |
| 1.60mm | 37.28 | 82.19 |

Difference Between GI Sheet and CR Sheet
GI Sheet (Galvanized Iron) is a CR sheet with a zinc coating applied via hot-dip galvanizing. The base material is the same cold-rolled steel, but GI carries a zinc layer (Z120/Z180/Z275) that provides built-in corrosion protection — no painting or post-treatment needed. CR Sheet (Cold Rolled) has no coating — it is bare bright steel with tighter dimensional tolerances and a smoother surface. Choose GI Sheet for outdoor, humid, or corrosive environments: roofing, exterior panels, and agricultural structures. Choose CR Sheet for indoor precision parts, deep drawing applications, or components that will receive powder coating, plating, or painting post-fabrication. GI Sheet costs 8–12% more than equivalent CR due to the zinc coating.
Get Material Grade AdviceGI Sheet Price in Mumbai — Per Kg, Per Piece, Per Sq Ft
GI Sheet price in Mumbai is quoted in three formats depending on buyer type: per kg (fabricators and traders), per piece (contractors buying 8x4 sheets), and per sq ft (roofing contractors). As of May 2026, GI Sheet price ranges from ₹55–₹78 per kg depending on thickness, zinc coating grade, and brand. For reference: a standard 0.5mm thick 8x4 GI Sheet weighs approximately 11.8 kg and costs ₹650–₹920 per piece. A 1.0mm thick 8x4 sheet weighs approximately 23.6 kg and costs ₹1,300–₹1,840 per piece. Price factors: thickness (thinner gauges carry a premium), coating grade (Z275 is ₹3–6/kg higher than Z120), brand (JSW and TATA carry a ₹2–4/kg premium over secondary), and quantity (bundle/coil lots are priced lower than per-piece purchases). Contact us for today's GI sheet price per kg in Mumbai.
GI Sheet Price Today — JSW, TATA, Secondary
GI Sheet prices in Mumbai track two inputs: hot-rolled steel base price (revised monthly by JSW and TATA) and LME zinc price (revised weekly).
