GP/GI Sheets
GP/GI sheets
Are you suffering from rusting of steel sheets at your construction site? GP and GI sheets are galvanized steel sheets used for roofing, cladding and outdoor infrastructure. GP stands for galvanised plain, while GI stands for galvanised iron, which are zinc-coated steel sheets designed for high corrosion resistance and durability in the appliance industry. Hi-Tech Engineers are the hub of steel solutions who fulfil the requirements of all types of galvanised steel sheets under one roof. We are one of the best GI sheets manufacturers in Punjab, and we are constantly offering defect-free galvanised sheets to our customers. Our GI sheets are sourced from the most valued and reputed manufacturers of the industry.
GP sheets suppliers in Bathinda are the first and foremost choice of the engineers and people to make the best deals in the business. The quality and consistency of providing the best sheets have made a remarkable brand value in the market. The galvanised steel and steel coils of GI sheets manufacturers in Mandi Gobindgarh are highly preferred and welcomed for their unmatchable quality. We help our customers to generate more ROI with our offers and deals of galvanized steel. The sizes of steel sheets are available with widths of (900, 1000, 1100, 1250, 1500 mm) and thicknesses from 0.30 mm to 3.0 mm. We supply the products from top manufacturers of India, including SAIL, JSPL, RINL, Kamdhenu, TATA, Jindal, APL Apollo, Surya, Jyoti TMT and Fortune TMT.
features of GP/GI sheets
Superior Corrosion Resistance and Longevity
The hot-dip galvanizing process, which coats the steel sheet with zinc, creates a robust protective layer. This sacrificial layer prevents rust by oxidizing before the base metal, for decades, even in humid or coastal environments.
Thermal Reflectivity
The shiny, metallic surface of GI sheets naturally reflects a significant portion of solar radiation. When used in roofing and wall cladding, this functional feature reduces heat penetration into buildings, lowering cooling costs and improving the overall thermal regulation of structures.
Self-Healing Property
The galvanizing process provides a unique self-healing characteristic where minor scratches or cuts are protected by the surrounding zinc. This avoids the need for frequent repainting or manual repairs, making it a cost-effective choice for industrial infrastructure.
Material Sourcing
We supply products from top manufacturers including:
SAIL, JSPL, RINL, Kamdhenu, TATA, Jindal, APL Apollo, Surya, Jyoti TMT, Fortune TMT, and many more.
All materials are tested and certified as per BIS/IS/ASTM standards to meet project specifications.
FAQs
How is a GI different from a GP sheet?
Galvanized Iron sheets, given their hot-dip zinc coating, are the go-to choice for robust outdoor roofing. On the other hand, Galvanized Plain sheets feature a smoother, shinier surface and a lighter zinc layer. This makes them well-suited for indoor applications, like appliances, and for automotive panels.
Are these sheets fire-resistant?
GI sheets are non-combustible and provide a high level of fire resistance due to the steel’s high melting point. While they do not catch fire, extreme temperatures can eventually compromise their structural integrity, so they should be used alongside other fire-rated building materials.
What is the life span of a GI sheet?
Under standard environmental conditions, well-maintained GI roofing sheets generally last between 20 and 30 years. Their lifespan depends heavily on the zinc coating thickness and exposure to air and moisture.
Are GI and GP sheets suitable for coastal and marine areas?
Standard GI sheets may corrode faster in salty coastal air. For these environments, suppliers recommend sheets with higher zinc coating, which use an aluminium-zinc alloy for superior salt-spray resistance and significantly better long-term protection.
