For a pitched roof in Malaysia, four materials dominate every project shortlist: PPGI metal deck sheet, clay interlocking tile, concrete interlocking tile, and fibre cement tile. Each carries a different standard, HS code, import duty, and performance profile under Malaysia’s two-season tropical climate — heavy monsoon rain from October to March and sustained heat year-round. This guide puts all four side-by-side so contractors, QSes, and homeowners can make an informed choice before the BoQ is finalised.
The Four Materials: Specs and Trade Data
PPGI Metal Deck Sheet (Trapezoidal / Corrugated)
The dominant choice for industrial, commercial, and low-cost residential buildings — and increasingly specified for modern residential work with cool-roof colours.
Standard material is PPGI to AS 1397 / ASTM A755: base metal G550 high-tensile or DX51D at 0.42–0.55 mm BMT, zinc coating Z275 (275 g/m²), PVDF or polyester topcoat. Common Malaysian profiles include Trimdek (Lysaght), TH Deck 762 (Thung Hing), and Ajiya Hi-Ten. Sheet lengths are custom-cut 2–12 m with coverage width 762–1,000 mm. Minimum pitch: 3°–5° for trapezoidal profiles.
Import data (PDK 2025): HS 7210701200 · Duty 15% · SST 0%
For zero exposed fasteners and pitches as low as 1.5°–3°, the Standing Seam / Clip-Lock variant (same HS code and duty) is the preferred commercial and premium residential specification.

Clay Interlocking Roof Tile
The premium traditional choice. Leading Malaysian manufacturer: GCI (Golden Clay Industries), Ayer Hitam, Johor — SIRIM certified. Standard: EN 1304 / MS EN 1024 for water absorption and modulus of rupture; MS 797 as reference. Typical service life 60–100 years. Profiles: S-pantile, Marseille/Double Roman, S-curve interlocking. Installed weight 38–50 kg/m² — the structural frame must be designed accordingly.
Import data (PDK 2025): HS 6905100000 · Duty 30% · SST 10%

Concrete Interlocking Roof Tile
The volume choice for Malaysian residential construction. The Monier Elabana S-curve (BMI Group) is the single most-installed tile type nationally. Manufactured and SIRIM-certified to MS 797: Part 1 (compressive strength and water absorption tested). Profiles: Elabana, Espana, Double Roman. Installed weight 40–55 kg/m². Service life 40–50 years.
Import data (PDK 2025): HS classification 6810.19 — no confirmed PDK 2025 8-digit code on this entry; verify current tariff with your supplier or customs agent before importing.

Fibre Cement Roof Tile
Autoclaved fibre-reinforced cement tile, predominantly Shera brand (Thai-sourced), available in Roman and Trilon profiles. Key differentiator: installed weight of only 16–22 kg/m² — roughly half the weight of concrete or clay tiles. This makes FC tile the practical choice for retrofits on lightweight frames and upper-storey extensions. Factory pre-painted; no specific Malaysian MS standard — verify the manufacturer’s data sheet for breaking load and water absorption.

Tropical Climate Performance
Heat and Radiant Load
Clay tile has the best thermal performance — the fired ceramic body stores and releases heat slowly, attenuating peak ceiling temperatures. PPGI metal deck on its own has the worst performance: a single-skin metal roof without insulation produces uninhabitable interior temperatures. The correct specification is always metal deck + rock wool or glass wool insulation blanket beneath the sheet. See Rock Wool Roof Insulation and Glass Wool Roof Insulation. Concrete and fibre cement tile perform comparably — moderate thermal mass, adequate with a properly ventilated roof space.
Monsoon and Water Resistance
All four perform adequately under Malaysian monsoon conditions when correctly installed. Failure modes differ:
- Metal deck: most failures occur at end laps and ridge/verge flashings. GI Metal Deck Ridge Capping and Metal Deck Flashing (Apron/Barge/Wall) are critical secondary elements.
- Clay and concrete tile: failures are typically broken or displaced tiles, deteriorated hip/ridge mortar, or absent underlay. The Roof Underlay / Sarking (Foil-Faced Breather Membrane) is increasingly standard on all tile roofs in high-rainfall zones.
- Fibre cement: similar tile failure modes; follow the manufacturer’s installation guide for required lap dimensions.
Coastal Environments
Within 5 km of the coast (east coast peninsular, Sabah, Sarawak coastal sites), upgrade PPGI to Zincalume® (ZAM/Az150) substrate with PVDF paint — or specify Standing Seam Clip-Lock with ZAM/PVDF. Clay tile is corrosion-immune by nature and remains the strongest coastal specification for tile roofs.
Decision Matrix
| Project Type | Recommended | Reason |
|---|---|---|
| Industrial warehouse / factory | PPGI metal deck (trapezoidal) | Lowest cost, lightweight frame, fast install |
| Commercial shophouse / low-rise | PPGI standing seam or concrete tile | Cost and programme driven |
| Landed residential (standard) | Concrete tile (Monier Elabana) | Proven, widely available, cost-effective |
| Landed residential (premium) | Clay tile (GCI interlocking) | Lifespan, aesthetics, investment retention |
| Mass-housing development | Concrete tile or fibre cement | Developer cost position |
| Retrofit on lightweight frame | Fibre cement tile | Half the weight — no reframing needed |
| Coastal / marine building | Clay tile or standing seam PVDF/ZAM | Corrosion resistance |
| Heritage / conservation | Clay tile | Authentic material, lifespan match |
| Low-pitch roof (< 10°) | PPGI standing seam | Only metal handles very low pitches |
Frequently Asked Questions
Which roofing material is best for Malaysia’s hot and wet climate? Clay tile offers the best all-round tropical performance — thermal mass moderates heat, and the fired ceramic body is inherently moisture-resistant. For budget-constrained projects, concrete tile with proper underlay and roof ventilation is the practical standard. Metal deck with rock wool insulation is the best cost-performance for commercial and industrial buildings.
What is the minimum pitch for metal roofing in Malaysia? Trapezoidal PPGI (Trimdek, Ajiya) requires 3°–5° minimum. Standing seam / clip-lock systems can go to 1.5°–3°. Tile roofs (clay, concrete, fibre cement) require approximately 15°–20°, depending on profile and manufacturer’s installation guide.
What HS codes apply to roofing materials in Malaysia? Clay tile: 6905100000 (30% duty, 10% SST). Concrete tile: 6810.19 (verify 8-digit with RMCD). Fibre cement tile: 6811822000 (10% duty, 5% SST). PPGI metal deck: 7210701200 (15% duty, 0% SST). All per PDK 2025.
What is the difference between PPGI and plain GI corrugated sheet? PPGI has a factory-applied organic paint layer (polyester or PVDF) over the zinc base — providing colour choice and extended corrosion protection. Plain GI Corrugated Sheet (HS 7210619200, 15% duty, 5% SST) carries zinc only and is suited to agricultural, temporary, and low-cost applications.
