Corrugated polycarbonate sheet — also called PC wave sheet or PC corrugated roofing — is the cost-effective daylighting roof for carports, agricultural canopies and livestock buildings. In 2026 our factory delivered this exact system for a combined carport and agricultural canopy project: a translucent roof that sheds rain fast along its wave channels, survives hail and keeps the space below bright without artificial lighting. The result is a roof that weighs roughly half as much as an equivalent FRP skylight and carries a 15-year yellowing warranty.
The Challenge
The client ran a farm with a covered parking area and an adjacent livestock canopy. They needed one lightweight, translucent roof system that would drain heavy rain quickly, match the wave profile of their existing steel roof sheets so the joint stayed watertight, and hold up to hail, snow load and long-term sun exposure — all at a lower cost than glass or multiwall polycarbonate panels.
Our Solution
Jietai manufactures corrugated polycarbonate sheet in the wave profiles 840, 900, 930, 970 and 1050 (750 and 820 available on request), with effective widths from 840 mm to 1050 mm and overall widths up to 1100 mm. Thickness runs from 0.8 mm to 3.0 mm, and sheets are cut to any project length up to 12 m. Every sheet carries a co-extruded UV layer on the weather face to stop yellowing.
| Parameter | Range |
|---|---|
| Thickness | 0.8 – 3.0 mm |
| Wave profiles | 840 / 900 / 930 / 970 / 1050 (750, 820 on request) |
| Effective width | 840 – 1050 mm |
| Overall width | 900 – 1100 mm |
| Wave height | 20 – 50 mm |
| Length | Custom, up to 12 m |
| Colours | Clear, lake blue, grass green, bronze, opal white, custom |
| UV layer | Co-extruded, weather face |
| Light transmission | 25% – 88% |
| Fire rating | B1 (GB 8624), UL94 V-2 |
| Service temperature | −40°C to +120°C |
For this project we supplied 1.5 mm clear sheet in the 840 profile so it mated with the client’s existing steel roofing, fixed with EPDM-washered self-drilling screws through every second crest. The agricultural canopy used the same profile on a steel frame above the livestock area, giving fast water run-off and full daylight below.
Results
- Fast drainage: the wave channels cleared heavy rain without ponding
- Up to 88% light transmission cut daytime lighting costs
- Roof weight of about 1.7 kg/m² for 1.5 mm sheet — roughly half an equivalent FRP skylight
- 15-year UV warranty against yellowing on the weather face

FAQ
What thickness of corrugated polycarbonate sheet should I use for a carport roof?
For most carports and canopies, 1.0–1.5 mm is standard. Step up to 2.0–3.0 mm where snow load, hail or wide purlin spacing demands extra strength.
What wave profile matches my steel roof sheets?
Match the profile number: 840 polycarbonate mates with 840 steel sheets, 900 with 900, and so on. Common profiles are 840, 900, 930, 970 and 1050.
Does corrugated polycarbonate sheet yellow over time?
No. The co-extruded UV layer protects the weather face, and Jietai backs it with a 15-year warranty against yellowing when installed UV side up.
Can I cut corrugated polycarbonate sheet to length myself?
Yes, with a fine-tooth saw or circular saw, but we supply sheets cut to any project length up to 12 m so there is no on-site cutting waste.
How much light does clear corrugated polycarbonate transmit?
Clear sheet transmits up to 88% of visible light. Tinted grades (lake blue, grass green, bronze, opal white) trade some light for solar control and privacy.
