Corrugated polycarbonate sheets — also called PC corrugated sheets or PC wave sheets — are the standard translucent roofing material for factory daylighting, carports, canopies, greenhouses and walkway covers in 2026. As a manufacturer, Jietai produces corrugated PC sheets in standard wave types of 840, 900, 930 and 970, thicknesses from 0.8 mm to 3.0 mm, and light transmission from 25% to 88%. A co-extruded UV layer keeps the sheet clear and impact-resistant for up to 15 years outdoors.

Wave Types and Profile Guide
The wave profile must match the existing roof so sheets overlap and seal correctly — an 840-type sheet matches an 840 steel roof profile, a 900-type matches 900, and so on. The table below lists the four standard wave types and their dimensions.
| Wave type | Effective width | Overall width | Wave height | Expansion factor |
|---|---|---|---|---|
| 840 | 840 mm | Approx. 1000 mm | 20 – 30 mm | 1.19 |
| 900 | 900 mm | Approx. 1100 mm | 20 – 30 mm | 1.22 |
| 930 | 930 mm | Approx. 1150 mm | 20 – 30 mm | 1.24 |
| 970 | 970 mm | Approx. 1250 mm | 25 – 50 mm | 1.29 |
Colours and Light Transmission
Clear sheets transmit the most daylight, up to about 88%; tinted sheets cut glare and heat. Available colours include clear, lake blue, grass green, bronze and opal, with custom RAL colours on request.
Thickness Selection by Application
Thinner sheets suit lightweight covers, while thicker sheets handle larger spans and higher wind or snow loads.
| Thickness | Typical application |
|---|---|
| 0.8 – 1.2 mm | Light covers, greenhouses, decorative panels |
| 1.5 – 2.0 mm | Carports, canopies, walkways, general roofing |
| 2.5 – 3.0 mm | Large spans, factory daylighting, high wind/snow areas |
Applications
Corrugated PC sheets are specified across industrial and agricultural projects in 2026: factory and warehouse daylighting roofs, carports and canopies, greenhouses and agricultural tunnels, walkway and corridor skylights, and fencing or partitions.
Why Choose Jietai
Jietai is a polycarbonate sheet manufacturer, not a reseller, so profile tooling, UV co-extrusion and quality control are handled in-house. Every sheet is produced to GB 8624 Class B1 and UL94 V-2 fire standards, carries a co-extruded UV layer rated for up to 15 years outdoors, and is cut to length to match your roof profile. Contact our team for a quote with your wave type, thickness, colour and quantity, and we will confirm the best specification for your project.
Frequently Asked Questions
What is the difference between corrugated PC sheet and fiberglass (FRP) skylight sheet?
Corrugated polycarbonate is roughly half the weight of FRP, will not shatter on impact, and carries a co-extruded UV layer that keeps it clear for up to 15 years outdoors instead of yellowing within a few seasons.
Which wave type should I choose for my roof?
Match the wave profile to your existing steel roof or glazed tile: an 840-type sheet overlaps an 840 profile, a 900-type matches 900, and so on. The four standard profiles are 840, 900, 930 and 970, with 1050 available for wider roofs.
How thick should corrugated polycarbonate be?
Use 0.8 to 1.2 mm for light covers and greenhouses, 1.5 to 2.0 mm for carports, canopies and general roofing, and 2.5 to 3.0 mm for large spans or areas with heavy wind and snow load.
How much light does corrugated polycarbonate transmit?
Clear sheets transmit up to about 88% of light. Transmission falls with thickness and colour: opal and tinted sheets diffuse the light and cut glare, with values down to about 25% for darker shades.
Can corrugated PC sheets be cut and installed easily?
Yes. Sheets are cut to length at the factory (up to 12 m) and can be trimmed on site with standard tools. The UV-protected side must face outward, and fasteners need pre-drilled oversize holes with EPDM washers to allow thermal movement.
