Multiwall Polycarbonate Sheet
Twin-wall, triple-wall and honeycomb structures — lighter and warmer than solid sheet, for roofing and greenhouses.
Carport & Canopy Sheet
Vehicle shelters, bus stops and entrance canopies — impact resistant, and it will not shatter onto a car.
Carports and shelters are where polycarbonate’s impact resistance earns its price. A hailstone, a falling branch or a thrown bottle cracks glass or acrylic and drops debris onto whatever is parked underneath. Polycarbonate absorbs the hit.
It also cold-curves, which is why so many bus shelters and entrance canopies use a gentle arc — the curve is formed on site from flat sheet, with no tooling cost.
Specification
| Property | Specification |
|---|---|
| Typical construction | Solid 3–6 mm, or twin-wall 6–10 mm |
| UV protection | Required — co-extruded on the exposed face |
| Cold-curving radius | Minimum approx. 150× thickness (solid), 175× (multiwall) |
| Colours | Clear, opal, bronze, grey — bronze and opal reduce solar gain |
| Thermal movement | Allow approx. 3 mm per metre; oversize fixing holes |
Typical applications
- Domestic and commercial carports
- Bus shelters and transport interchanges
- Building entrance canopies
- Cycle shelters and storage covers
- Walkway and loading bay covers
Minimum order and lead time
This grade ships from 100 m² or 1 tonne — a trial pallet, not a full container. Standard sizes and stock colours run in 7–10 days; non-standard thickness or width in 12–18 days; add 3–7 days for CNC cut-to-size work. Quoted in USD on FOB, CIF or DDP terms.

Questions buyers ask
Clear or tinted for a carport?
Bronze or opal if the shelter faces south and heat build-up matters; clear if the space underneath needs light. Tinted sheet cuts solar gain noticeably without making the structure dark.
Can the sheet be curved without heating it?
Yes. Solid sheet cold-curves to about 150× its thickness — 3 mm sheet to roughly a 450 mm radius. Tighter curves need thermoforming, which we do in-house.
Will hail damage it?
Polycarbonate is the standard specification precisely because it resists hail. Acrylic and glass in the same location crack; polycarbonate absorbs the impact and recovers.
