Galvanized steel. Coated, coloured, certified.
The complete galvanized catalogue: hot-dip GI coils, corrugated roofing sheets, pre-painted PPGI coils and finished sheets in any RAL colour. Supplied mill-direct to roofing contractors, PEB fabricators, façade firms and infrastructure projects across the UAE, GCC and Africa.
A galvanized division built for roofs, frames and envelopes.
From the PEB fabricator rolling 0.50 mm trapezoidal sheets across a 200 m logistics shed, to the architect specifying PVDF-coated RAL 7016 panels on a hotel rainscreen. Every project rests on the same question: which coating, which substrate, which paint system, for which exposure.
TIC Dubai's GI division supplies that decision: hot-dip galvanized coil and sheet to ASTM A653, EN 10346 and JIS G3302, and pre-painted PPGI in PE, SMP, HDP and PVDF systems to any RAL colour, from a single coil to multi-thousand-tonne programmes.

Z60 to Z275, decoded.
Zinc coating mass is the single most important variable in GI specification, as it determines corrosion life, market acceptance and price. The number after the "Z" is the total mass of zinc in g/m² deposited across both faces of the sheet.
| Grade | Total zinc | Per face | Thickness | Service life | Typical market & use |
|---|---|---|---|---|---|
| Z60 | 60 g/m² | ≈ 30 g/m² / face | ≈ 4 µm / face | Internal / dry, short-life | Internal dry-wall studs, internal HVAC ducting, painted secondary use |
| Z80 | 80 g/m² | ≈ 40 g/m² / face | ≈ 5.6 µm / face | Internal / mild exposure | Door frames, sheet-metal fabrication, internal cladding, white-goods |
| Z100 | 100 g/m² | ≈ 50 g/m² / face | ≈ 7 µm / face | Mild atmospheric: 10 – 15 years | Light roofing, internal ducting, fabrication, PPGI substrate (entry) |
| Z120 | 120 g/m² | ≈ 60 g/m² / face | ≈ 8.5 µm / face | Atmospheric: 15 – 20 years | Commercial roofing, PPGI substrate, sandwich panels, fabrication |
| Z180 | 180 g/m² | ≈ 90 g/m² / face | ≈ 12.5 µm / face | Industrial / coastal: 20 – 30 years | Industrial roofing, PEB envelope, coastal commercial roofing, PVDF substrate |
| Z275 | 275 g/m² | ≈ 137.5 g/m² / face | ≈ 20 µm / face | Heavy industrial / coastal: 30 – 50+ years | Long-life roofing, coastal cladding, infrastructure, premium PPGI |
Export markets prefer different coating standards. Z80 / Z100 dominates parts of Asia and Africa, Z120 / Z180 is the GCC commercial standard, Z275 is the long-life coastal premium. Specify by project requirement, budget, corrosion exposure and destination market.
PE, SMP, HDP, PVDF: the architect's reference.
The paint system on a PPGI coil decides how it weathers, how it holds colour and how long the building keeps looking new. Four chemistries cover the full cost / performance spectrum.
Polyester
Economical roofing & cladding, inland exposure, short-life projects
Silicone-Modified Polyester
Commercial roofing in moderate UV / atmospheric exposure
High-Durability Polyester
Long-life industrial roofing, GCC inland & semi-coastal projects
Polyvinylidene Fluoride (Kynar 500 / Hylar 5000)
Architectural facades, coastal Gulf, premium long-life roofing
Any RAL classic, design or effect colour.
PPGI is custom-batched against the RAL colour standard. Stock colours below ship faster; bespoke RAL is produced to order against the project's minimum tonnage.

Galvanized Iron (GI) and PPGI, defined.
Galvanized Iron (GI) is a generic industry term for hot-dip galvanized steel: a low-carbon steel substrate continuously coated with a metallurgically bonded layer of zinc on a Sendzimir line. PPGI (Pre-Painted Galvanized Iron) is GI coated with an organic paint film, polyester (PE), silicon-modified polyester (SMP), high-durability polyester (HDP) or polyvinylidene fluoride (PVDF), in any RAL colour. GI and PPGI are the dominant envelope, roofing and PEB substrates across the GCC, specified to ASTM A653, EN 10346 and JIS G3302, with zinc coatings Z80 to Z275 (g/m²) and paint systems engineered for life from 10 to 40+ years.

| Property | GI (hot-dip galvanized) | Galvalume (Al-Zn) |
|---|---|---|
| Coating composition | 99 % zinc | 55 % Al + 43.4 % Zn + 1.6 % Si |
| Standard | ASTM A653 / EN 10346 | ASTM A792 / EN 10346 |
| Coating designation | Z80 – Z275 | AZ50 – AZ185 |
| Atmospheric corrosion life | Good | 2 – 4× longer than equivalent zinc |
| Cut-edge protection | Strong (sacrificial Zn) | Weaker, relies on Zn at the edge |
| High temperature | Up to ~ 230 °C | Up to ~ 315 °C |
| Appearance | Bright spangle / smooth | Silvery, fine spangle |
| Paintability | Excellent for PPGI | Excellent, Galvalume painted (PPGL) |
| GCC market share | Dominant industrial / roofing | Premium roofing / cold storage / industrial |
Z120 vs Z275 (zinc coating mass)
Two zinc coating classes for GI, Z120 is the GCC commercial industrial standard, Z275 is the long-life coastal premium.
| Property | Z120 | Z275 |
|---|---|---|
| Total zinc (g/m²) | 120 | 275 |
| Per face (g/m²) | 60 | 137.5 |
| Zinc thickness per face | ~ 8 µm | ~ 20 µm |
| Standard | EN 10346 / ASTM A653 | EN 10346 / ASTM A653 |
| Service life (C2 atmosphere) | 30 – 50 years | 60 – 100 years |
| Service life (C4 coastal / industrial) | 8 – 15 years | 25 – 40 years |
| Service life (C5-M severe marine) | 3 – 7 years | 10 – 20 years |
| Typical use | Roofing, ducting, PEB internal | Coastal Gulf, infrastructure, premium PEB |
| Cost premium | Baseline | + 15 – 25 % |
Hot Dip vs Electro Galvanized
Two zinc-coating processes, hot-dip is the industrial standard, electro-galvanized is the thin-coating cold-rolled alternative.
| Property | Hot Dip Galvanized (HDG / GI) | Electro Galvanized (EG / GA) |
|---|---|---|
| Process | Continuous immersion in molten zinc (~ 460 °C) | Electrolytic zinc deposition (room temperature) |
| Coating mass | Z80 – Z600 (60 – 460 µm) | 10 – 40 g/m² (1.5 – 5 µm) |
| Coating uniformity | Slight spangle, ~ 8 – 20 µm typical | Highly uniform, very thin |
| Substrate behaviour | Reduced cold-form / paint adhesion (heat affect) | Cold-rolled retains drawability |
| Outdoor / heavy corrosion | Yes, designed for exposure | No, light atmospheric only |
| Auto / appliance use | Limited | Standard for car body & appliance |
| Cost | Lower (mass production) | Higher (electrochemical) |
PPGI Paint Systems
Four organic coating chemistries cover the full cost / performance spectrum for PPGI.
| System | Top coat (µm) | UV / colour retention | Life (years) | Best use |
|---|---|---|---|---|
| PE (Polyester) | 18 – 25 | Moderate | 10 – 15 | Cost-effective roofing & cladding |
| SMP (Silicon-Modified) | 22 – 25 | Good | 15 – 20 | Industrial roofing, mid-tier facade |
| HDP (High Durability) | 25 – 28 | Very good | 20 – 25 | Premium roofing, coastal facade |
| PVDF (Kynar) | 25 – 30 | Excellent | 30 – 40 | Architectural facade, premium hospitality |
GI / PPGI procurement guide
Six-step framework for any GI / PPGI specification.
- 1. Define corrosion category
Identify ISO 9223 corrosivity category at the project site, C2 (rural / interior), C3 (urban), C4 (industrial / Gulf coastal), C5-M (severe marine / chemical). The category drives zinc mass and paint system.
- 2. Select zinc mass (or AZ)
Z80, interior dry. Z120, GCC commercial industrial standard. Z180, extended industrial / mild coastal. Z275, coastal Gulf / infrastructure / long-life premium. AZ150 / AZ185, Galvalume premium roofing.
- 3. Choose substrate grade
CQ (commercial quality), general sheet. DDQ (deep drawing), formed profiles. S280GD / S350GD / S550GD, structural roof / wall purlins. SGCC / SGCH, JIS commercial / hard.
- 4. Specify paint system (PPGI)
PE, cost-effective roofing, 10 – 15 yr. SMP, industrial roofing, 15 – 20 yr. HDP, premium roofing / coastal, 20 – 25 yr. PVDF, architectural premium / hospitality, 30 – 40 yr.
- 5. Confirm RAL colour and gloss
Stock RAL, 3009, 5010, 6005, 7035, 7016, 9002, 9006, ship faster. Custom RAL produced to order against minimum tonnage (typically 25 – 50 t). Gloss 30 / 50 / 70 specified by paint system and project requirement.
- 6. Plan documentation and freight
Mill test certificate (chemistry + zinc mass + coating adhesion), paint system report (T-bend, MEK rub, salt spray), RAL colour swatch, packing list with coil weights / IDs. Coil eyes vertical for storage, horizontal for cutting.
GI / PPGI inspection checklist
