What is GI Sheet 8x4 ft?

GI sheet (Galvanized Iron Sheet) is steel sheet coated with zinc through hot-dip galvanization process, providing excellent corrosion resistance for outdoor and moisture-prone applications. The standard 8x4 ft (2440mm x 1220mm) size is the most common industrial sheet dimension in India, widely used in roofing, construction, and fabrication industries. The zinc coating protects the underlying steel from rust and oxidation, offering 15-25 year lifespan depending on coating weight and environment. GI sheets are manufactured by passing cold rolled or hot rolled steel through molten zinc bath at 450°C, creating a metallurgical bond. Unlike uncoated steel (MS/HR) that rusts within months outdoors, GI sheets maintain structural integrity and appearance for decades, making them the preferred choice for roofing, ducting, cladding, and outdoor applications.

Technical Q&A

Verified Procurement Intelligence

What is the price of 0.5mm GI sheet 8x4 ft?
0.5mm GI sheet (8x4 ft) with 120 GSM coating costs approximately ₹770 per sheet (13.1 kg). This is the most common thickness for residential roofing. For 180 GSM or 275 GSM coating, add ₹100-150 per sheet. Bulk discounts available for 100+ sheets. Contact +91 8459121717 for contractor rates.
What GSM coating should I choose for roofing?
For Mumbai/Thane (normal environment): 120 GSM is standard, offers 12-15 year life. For coastal areas (Vasai, Virar, coastal Mumbai): 180 GSM recommended, 15-20 year life. For marine/industrial zones: 275 GSM for maximum protection. 120 GSM is most economical for inland residential roofing.
What is the weight of 0.8mm GI sheet 8x4 ft?
0.8mm GI sheet (8x4 ft) with 120 GSM coating weighs approximately 20.4 kg (45 lbs). This thickness is commonly used for corrugated roofing and heavy-duty applications.
What is the difference between GI sheet and MS sheet?
GI (Galvanized) has zinc coating for rust protection, lasts 15-25 years outdoors. MS (Mild Steel/HR) has no coating, rusts within months outdoors. GI costs 8-12% more but eliminates painting and replacement. Use GI for any outdoor application; MS only for indoor structural work.
Which thickness is best for residential roofing?
For standard residential roofing: 0.4-0.5mm is most common (economical, adequate strength). For areas with heavy rain/wind: 0.6-0.8mm for extra durability. For corrugated roofing sheets: 0.5-0.8mm depending on span. Thicker material costs more but lasts longer under foot traffic during maintenance.
Can GI sheets be used for HVAC ducting?
Yes, GI sheets are standard for HVAC ducting. For air conditioning ducts: 0.4-0.6mm with 80-120 GSM coating is typical. The zinc coating prevents internal corrosion from condensation. Thinner gauges (0.3-0.4mm) for small residential ducts; thicker (0.6-0.8mm) for large commercial installations.
How long do GI sheets last?
GI sheet lifespan depends on coating weight and environment: 120 GSM lasts 12-15 years normal, 8-10 years coastal. 180 GSM lasts 15-20 years normal, 10-12 years coastal. 275 GSM lasts 20-25 years normal, 12-15 years coastal. Industrial/chemical environments reduce life by 20-30%.
Do you deliver GI sheets in Navi Mumbai and Thane?
Yes, we deliver across Mumbai, Navi Mumbai, Thane. Same-day dispatch for Vasai-Virar region. Next-day delivery for other Mumbai areas. For bulk orders (100+ sheets), we arrange direct mill delivery for better logistics and pricing.
What is regular spangle vs zero spangle?
Regular spangle has visible zinc crystal pattern (flower-like appearance), economical, used for unpainted roofing. Zero spangle has smooth surface without crystals, better for painting, used as PPGI base. Regular spangle is standard for roofing; zero spangle costs ₹1,000-2,000 more per ton.
Can GI sheets be painted?
Yes, but surface preparation is critical. New GI sheets should be weathered for 6-12 months or treated with acid etch primer before painting to ensure adhesion. For immediate painting, use zinc-compatible primers. Alternatively, choose pre-painted GI (PPGI/color-coated) which comes factory-painted.
Do you offer secondary GI sheets?
Yes, we stock secondary GI sheets at 15-20% discount. These have minor coating imperfections, slight surface marks, or edge irregularities but maintain corrosion protection. Ideal for roofing sheds, warehouses, temporary structures, or applications where appearance is less critical. Available in common thicknesses (0.4-1.2mm).
What is the HSN code for GI sheet?
HSN code for GI sheet is 7210. GST rate is 18%.
