GI Corrugated Roofing Sheets
Hot-dip galvanized corrugated and trapezoidal roofing sheets, supplied in custom lengths, profiles and zinc coatings for warehouses, factories, infrastructure projects and agricultural buildings across the GCC and Africa.
Technical overview.
GI corrugated sheet is the standard industrial roofing and cladding substrate of the region, a hot-dip galvanized coil roll-formed into a structural profile that delivers span, drainage, walkability and 30+ year service life when correctly specified.
A corrugated GI sheet is a roll-formed panel produced from hot-dip galvanized coil. The profile (corrugation pitch, depth and rib geometry) is engineered for span, load and water-shedding. Sheets are cut to project-length on the roll-forming line, so there is no theoretical length limit; a single sheet can run from ridge to eave on most buildings.
Configured to your specification.
Corrugated GI is produced to project requirement. Specify the parameters below and we'll revert with a quote, mill availability and lead time.
Substrate, coating, certification.
Where corrugated gi is specified.
- Industrial warehouses & factory roofing
- Pre-engineered building (PEB) envelope
- Logistics & cold-storage facilities
- Cladding for industrial & infrastructure projects
- Agricultural sheds, poultry houses & livestock shelters
- Fencing & site hoarding for construction projects
- Bus shelters, canopies & temporary structures
- Mining, oil & gas non-process buildings
Specify by zinc coating.
Zinc coating mass (g/m² total, both faces) is the primary GI variable. Match the grade to the exposure environment and project life.
| Grade | Zinc (g/m²) | Per face | Service life | Typical use |
|---|---|---|---|---|
| Z60 | 60 g/m² | ≈ 30 g/m² / face | Internal / dry, short-life | Internal dry-wall studs, internal HVAC ducting, painted secondary use |
| Z80 | 80 g/m² | ≈ 40 g/m² / face | Internal / mild exposure | Door frames, sheet-metal fabrication, internal cladding, white-goods |
| Z100 | 100 g/m² | ≈ 50 g/m² / face | Mild atmospheric: 10 – 15 years | Light roofing, internal ducting, fabrication, PPGI substrate (entry) |
| Z120 | 120 g/m² | ≈ 60 g/m² / face | Atmospheric: 15 – 20 years | Commercial roofing, PPGI substrate, sandwich panels, fabrication |
| Z180 | 180 g/m² | ≈ 90 g/m² / face | Industrial / coastal: 20 – 30 years | Industrial roofing, PEB envelope, coastal commercial roofing, PVDF substrate |
| Z275 | 275 g/m² | ≈ 137.5 g/m² / face | Heavy industrial / coastal: 30 – 50+ years | Long-life roofing, coastal cladding, infrastructure, premium PPGI |
