Synthetic Resin Roof Tiles — ASA Surface, 30-Year Warranty
ASA synthetic resin roof tiles for hot, humid, and coastal markets, available with matching accessories.
ASA Synthetic Resin Roof Tiles
Co-extruded ASA + PVC roof tiles engineered for 20–30 years of UV-stable, corrosion-free service in hot and humid climates.
Key Features
- ASA surface layer (≥0.15mm) — superior UV resistance, color holds at ΔE≤5 over 10 years
- Rigid PVC core — strong, flame-retardant (Class B1), and cost-effective
- Lightweight 3.0–4.5 kg/㎡ — corrosion-proof, won't rust like steel sheet
- Excellent heat & noise insulation — quiet in heavy rain, cooler interiors

Specifications
Material & Co-Extrusion Structure
Our tiles use a co-extruded structure: a weatherproof ASA surface layer molecularly fused over a rigid PVC core — cheap PVC for the frame, premium ASA as the "sun armor". Available as 2-layer (ASA+PVC) or 3-layer (ASA+PVC+ASA, weatherproof on both faces).
| Material | Role | Note |
|---|---|---|
| ASA | Top weather layer | Best UV / anti-aging / color retention |
| PMMA | Premium top layer | High gloss & durability |
| PVC | Structural core | Rigidity + flame retardance + low cost |
| ABS | Low-end top layer | ⚠ Yellows & chalks outdoors — we do NOT use ABS surface |
ASA layer is the quality line
A genuine ASA surface of ≥0.15mm is the difference between a tile that lasts decades and one that fades in a year. Premium ASA tiles hold color at ΔE≤5 over ten years. We can provide a cross-section sample so you verify the real ASA thickness — a key check when sourcing.
Profiles, Thickness & Applications
Profiles & thickness
- Standard corrugated, small-wave (T), wide-span, antique/glazed-look, Spanish & Roman profiles
- 2.0mm — sheds, low-budget builds
- 2.5mm — mainstream housing & factories (top export choice)
- 3.0–3.5mm — large spans, high wind load
True weight is a quality tell: 2.0mm≈2.4–2.8, 2.5mm≈3.0–3.5, 3.0mm≈4.0–4.5 kg/㎡. Over-heavy tiles are bulked with cheap calcium filler.
Where it fits best
- Rural / self-build housing & roof renovation (pitch conversion)
- Farms & livestock sheds (resists corrosion better than metal)
- Chemical / plating plants (acid & alkali resistant)
- Factories, carports, heritage & new-Chinese-style builds
Not recommended: very low slope (<10°), heavy load-bearing / walk-on roofs, or where Class-A non-combustible is required (resin is B1).
ASA Resin vs ABS vs Steel Roofing — Which to Choose
Synthetic resin (ASA) tiles win on corrosion resistance, insulation and noise. The key is a genuine ASA surface layer — not cheap ABS that yellows within a year or two.
| Criteria | ASA Synthetic Resin | ABS-surface Resin (low-end) | Color Steel Sheet |
|---|---|---|---|
| UV / weather resistance | Excellent (ASA built for outdoor UV) | Poor (yellows & chalks in 1–2 yrs) | Fair (coating fades) |
| Corrosion / chemical | Excellent (won't rust, acid/alkali proof) | Good | Poor (rusts, esp. coastal/farm) |
| Heat insulation | Excellent (low conductivity) | Good | Poor (hot, needs extra layer) |
| Rain noise | Quiet | Quiet | Loud |
| Service life | 20–30 years | 5–10 years | 10–15 years |
| Best for | Self-builds, farms, factories, renovation in hot/humid/coastal areas | Lowest-budget temporary use | Budget industrial sheds |
For tropical and coastal projects in Southeast Asia and Africa, a true ASA synthetic resin tile resists sun, salt and acid far better than steel or ABS — ask us for an ASA-layer cross-section to verify quality.
Frequently Asked Questions
What is a synthetic resin (ASA) roof tile made of?
It is a co-extruded tile with a weather-resistant ASA surface layer over a rigid PVC core. The ASA layer (≥0.15mm) blocks UV and keeps colors stable, while the PVC core gives strength at low cost.
What thicknesses do you offer and which should I choose?
2.0mm for sheds and low-budget builds, 2.5mm for mainstream housing and factories (most popular export choice), 3.0–3.5mm for large spans and high wind loads.
How is ASA resin tile better than color steel sheet?
It does not rust, insulates far better against heat, is much quieter in rain, and resists acid/alkali — ideal for coastal areas, farms, chemical plants and hot climates where steel corrodes and overheats.
What is the MOQ and can I get samples?
Resin tiles have a low MOQ that suits trial orders, and we ship free samples worldwide so you can confirm thickness, ASA surface quality and color before bulk purchase.
Where are resin tiles not recommended?
Very low slopes (under ~10°) risk poor drainage, and they are not for heavy load-bearing or walk-on roofs. For premium 50-year metal-look roofing, consider our stone coated metal tiles instead.
