What is GI Coil? (Galvanized Iron Coil Full Form)

GI coil stands for Galvanized Iron Coil. Galvanized iron coils are steel coils coated with a layer of zinc through the hot-dip galvanization process. The zinc coating provides excellent corrosion resistance, protecting the underlying steel from rust and oxidation. GI coils are manufactured by passing cold rolled or hot rolled steel through a molten zinc bath at approximately 450°C, resulting in a metallurgical bond between zinc and steel. The zinc coating thickness ranges from 80 GSM to 275 GSM depending on application requirements. GI coils are the most widely used coated steel product in construction, roofing, automotive, and HVAC industries.

Industrial Applications

GI Coil Weight Calculator

To calculate GI coil weight: Weight (kg) = Length (m) × Width (m) × [Thickness (mm) × 7.85 + Coating Weight]. Example: A GI coil of 1.2m width, 0.5mm thickness, 120 GSM coating, and 200m length weighs approximately 1,000 kg. Note: Coating adds approximately 0.017mm per 120 GSM. For precise weight calculations including coating weight, contact our technical team.

GI Coil HSN Code

The HSN code for GI coil is 7210 (Flat-rolled products of iron or non-alloy steel, of a width of 600mm or more, plated or coated with zinc). GST rate: 18%. This HSN code applies to galvanized coils, sheets, and corrugated roofing materials with zinc coating.

Technical Q&A

Verified Procurement Intelligence

What is GI coil full form?
GI coil stands for Galvanized Iron Coil. It refers to steel coils coated with zinc through hot-dip galvanization for corrosion protection.
What is the current GI coil price in India?
GI coil prices in India range from ₹56,000 to ₹62,000 per metric ton depending on coating weight (80-275 GSM) and base thickness. For today's exact price in Mumbai, contact us at +91 8459121717.
What is the difference between GI coil and MS coil?
GI (Galvanized Iron) coils have zinc coating for corrosion resistance and are used for outdoor applications. MS (Mild Steel/HR) coils have no coating and rust easily. GI costs 8-12% more but lasts 15-25 years vs 1-2 years for MS in outdoor conditions.
What are the uses of GI coil?
GI coils are used in roofing sheets, HVAC ducting, automotive body panels, electrical appliances, storage tanks, PEB structures, corrugated sheets, gutters, and as base material for color-coated steel (PPGI).
What GSM coating should I choose?
Choose 80 GSM for indoor use, 120 GSM for standard roofing (10-15 year life), 180 GSM for coastal areas (15-20 years), and 275 GSM for severe corrosion environments (20-25 years). Our technical team can recommend based on your location.
What is the difference between regular spangle and zero spangle?
Regular spangle has visible zinc crystals, is economical, used for unpainted roofing. Zero spangle has smooth surface with no crystals, better for painting, used as PPGI base material. Zero spangle costs ₹1,000-2,000 more per ton.
Do you provide GI coil cutting and profiling services?
Yes, we offer slitting, CTL (Cut-to-Length), and profile cutting services through Sagar Metal Cutting Works. Corrugated profiles, standing seam, and custom shapes available.
What is the minimum thickness available in GI coil?
We stock GI coils from 0.3mm to 3.0mm base metal thickness. For roofing, 0.4-0.5mm is most common. For structural use, 0.8-3.0mm is recommended.
Do you supply GI coils outside Mumbai?
Yes, we deliver pan-India. Same-day dispatch for Mumbai region; 2-5 days for other cities like Pune, Surat, Ahmedabad, Bangalore through trusted transport partners.
What is the HSN code for GI coil?
HSN code for GI coil is 7210. GST rate is 18%.
Do you offer secondary GI coils?
Yes, we stock secondary GI coils at 15-20% lower cost. These have minor coating imperfections or edge marks but maintain corrosion protection. Ideal for roofing sheds, warehouses, or applications where aesthetics are less critical.
How long does GI coating last?
GI coating life depends on environment and coating weight: 120 GSM lasts 10-15 years in normal conditions, 15-20 years in dry climates. Coastal/industrial areas reduce life by 30-40%. Higher GSM increases durability.
