GI Composite Decking Sheets
High-rib composite metal floor decking sheets acting as permanent shuttering and slab reinforcement.
Premier Manufacturer of GI Composite Decking Sheets
Zinco Roofing Solution is recognized across Western India as the leading manufacturer and engineering provider of GI Composite Decking Sheets. Designed to withstand the rigorous operational demands of industrial manufacturing plants, cold storage complexes, logistics hubs, and commercial buildings, our GI Composite Decking Sheets systems offer unmatched structural durability, aesthetic appeal, and weather resistance.
If you are evaluating composite decking sheet price for a new project, ask about load tables and material grade first. We supply metal decking sheets and steel decking for mezzanine floors with stamped engineer calculations, and as a decking sheet manufacturer we deliver roof deck sheets in ready-to-fix lengths that cut site waste.
When sourcing structural solutions, factory project managers and structural consultants require absolute material integrity. Our state-of-the-art roll-forming lines process high-tensile steel and specialized polymer substrates engineered specifically for high-humidity coastal climates and heavy industrial chemical environments. Working with a dedicated metal floor decking price guarantees that your facility benefits from international standards of thermal insulation, wind load resistance, and 100% leak-proof reliability.

Modern architectural profiles combining high structural strength with sleek visual aesthetics and sound insulation.
Composite Decking Sheet Price: What Actually Drives It
Decking sheets are specified on load tables, not on thickness alone. Before comparing composite decking sheet price across suppliers, confirm the steel grade, deck profile, and the engineering that comes with it.
1. Load tables must match your design
A composite decking sheet price is meaningless without the load-span table that backs it. We provide stamped calculations for each profile, so your consultant can sign off without re-verification.
2. Galvanising weight matters in coastal Mumbai
Near the coast, zinc coating below 180 GSM corrodes early in roof decks. Confirm the coating weight in your quote — it is a bigger lifetime cost factor than the initial decking sheet price.
3. Check the decking sheet manufacturer’s QC
Roll-formed decks vary in profile tolerance and camber. Ask about in-line inspection and gauge verification — a decking sheet manufacturer with documented QC delivers flatter, faster-to-fix sheets.
Frequently Asked Questions (FAQ)
What is the average GI decking sheet price per sq ft in Mumbai?
GI composite floor decking sheets range from ₹62 to ₹85 per sq ft for 0.80mm thickness, ₹74 to ₹98 per sq ft for 1.0mm thickness, and ₹92 to ₹120 per sq ft for heavy-duty 1.2mm thickness (245 to 350 MPa yield strength, 120–275 GSM zinc coating).
What is the specification of GI floor decking sheets (44/130 & 52/75)?
The industry standard profile is 44mm or 52mm crest depth with embossed shear keys for composite concrete bonding. Cover width is typically 960mm to 1020mm with steel grades Fe 250 to Fe 350, eliminating timber formwork and acting as positive tensile reinforcement.
How to calculate GI deck sheet weight? (1mm GI deck sheet weight)
For a standard 1.0mm thickness GI composite deck sheet, the weight is approximately 9.85 kg to 10.45 kg per square meter (approx 0.92 to 0.97 kg per sq ft) depending on the embossed profile depth. An 0.8mm deck sheet weighs approx 8.10 kg/m².
Where are GI composite decking sheets used in construction?
GI decking sheets are used in multi-storey steel buildings, warehouse mezzanine floors, industrial platforms, and flyover bridge slabs to create high-strength reinforced concrete composite floors rapidly without bottom shuttering.
