Corrugated Polycarbonate Sheets for B2B Roofing Projects
Factory-direct corrugated PC sheets for industrial skylights, warehouse roofing, greenhouses, canopies and daylighting strips. Bakway supplies UV-protected panels that match Greca, sine wave, trapezoidal, Trimdek and custom metal roofing profiles.
Profile Matching for Roofing and Skylight Projects
Corrugated polycarbonate sheets are often installed together with metal roofing. The key procurement check is not only thickness: the wave height, pitch, cover width and overlap must match the existing roof profile so the translucent sheet can seal correctly with the metal sheet.
Greca and Trapezoidal
Common choices for industrial skylight strips and warehouse roofs where the PC sheet overlaps with profiled metal roofing.
Sine Wave and Round Wave
Used for greenhouses, shelters, patios and lightweight roofing where curved wave appearance is preferred.
Trimdek and Local Profiles
Profile matching can be reviewed against your metal sheet drawing, sample or project roof profile.
UV Co-Extrusion
Outdoor panels can be supplied with UV protection to reduce yellowing and brittleness under sunlight exposure.
Why Choose Polycarbonate over Fiberglass (FRP)?
FRP roofing sheets are still used in some daylighting projects, but buyers often move to corrugated polycarbonate when they need clearer light, cleaner handling and better impact behavior. The right choice depends on roof profile, budget, service life and replacement risk.
| Comparison Feature | Bakway Corrugated PC | Standard FRP Fiberglass |
|---|---|---|
| Impact resistance | Virtually unbreakable under normal roof impact conditions | Brittle and can crack or splinter |
| Light quality | Clear panels can reach about 90% light transmission | Often hazy and yellows faster |
| Durability | Flexible sheet behavior helps reduce spider cracking | Rigid structure is more prone to cracks |
| UV protection | Co-extruded UV layer available | Gel coat can degrade over time |
| Handling | Clean cutting and installation when processed correctly | Fiberglass handling can irritate skin |
Applications for Corrugated PC Roofing Sheets
Corrugated polycarbonate is best used where a roof needs daylight and weather protection without the weight of glass. For each application, confirm roof slope, purlin spacing, fastener type, washer material, overlap and thermal expansion allowance.
Industrial skylights
Daylighting strips for factories, warehouses and public buildings where panels need to match metal roof sheets.
Greenhouses and shelters
Transparent or colored roofing for agriculture, garden structures, livestock sheds and drying areas.
Canopies and walkways
Lightweight panels for parking covers, corridors, awnings and temporary structures.
Replacement projects
Used when old FRP sheets need better transparency, cleaner handling or improved impact resistance.
Technical Datasheet for Corrugated Sheet Review
Final values depend on thickness, profile, color, UV side and installation conditions. Use the table below as a procurement starting point before sample approval or profile matching.
| Parameter | Typical Options | Buyer Check |
|---|---|---|
| Thickness | 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm | Confirm purlin spacing, wind load and hail risk. |
| Profiles | Greca, sine wave, trapezoidal, Rome, Trimdek and custom profile | Send drawing or sample for roof profile matching. |
| Light transmission | Clear about 90%; opal and bronze lower by color | Check daylight target, glare and heat gain. |
| Service temperature | -40°C to +120°C typical range | Allow thermal expansion in fixing holes and overlaps. |
| UV layer | Co-extruded UV protection available | Specify outdoor side and warranty expectation. |
| Processing | Custom length, profile development, packing and loading plan | Confirm maximum sheet length and container loading. |
Installation and RFQ Checks
Most corrugated roofing problems come from profile mismatch, wrong fastener holes, insufficient overlap or ignoring thermal movement. Before quotation, send the information below so the factory can quote the correct panel instead of a generic sheet.
- Roof profile name, drawing, pitch, cover width or metal sheet sample.
- Thickness, color, UV side, required length and expected overlap method.
- Application: warehouse skylight, greenhouse, canopy, shelter, carport or replacement project.
- Support spacing, roof slope, screw type, washer material and local wind or hail exposure.
- Quantity, destination, packing method, container loading limit and delivery schedule.

Industrial Corrugated PC Roofing Specifications
| Profile | Thickness | Pitch / depth | Max span (purlins) | Typical use |
|---|---|---|---|---|
| Classic corrugated (CR) | 0.8–1.5 mm | 76 / 18 mm | 0.8–1.0 m | Sheds, carports, warehouses |
| YXL trapezoidal | 0.8–1.5 mm | 125 / 25 mm | 0.9–1.2 m | Industrial roofing, canopies |
| YXI trapezoidal | 0.8–1.5 mm | 76 / 20 mm | 0.8–1.1 m | Industrial cladding, facades |
| Ribbed / box profile | 1.0–2.0 mm | 114 / 30 mm | 1.0–1.5 m | Heavy industrial, cold storage |
Profile-matched tooling is available for most metal roofing profiles. Send a profile drawing or sample photo and we will confirm the exact tool before quoting.
What thickness corrugated polycarbonate do I need?
0.8–1.0 mm for standard sheds and carports, 1.0–1.2 mm for industrial roofing with normal snow loads, 1.5–2.0 mm for heavy snow or hail zones. Confirm the regional snow/wind load with our engineers before ordering.
Can corrugated polycarbonate replace corrugated metal roofing?
Yes for daylighting and corrosion-prone sites: PC is 10× lighter than metal, never rusts, and transmits 60–80% daylight while blocking UV. Use matching profiles so existing purlins and flashings work unchanged.
What is the maximum span for corrugated PC without purlins?
As a rule of thumb, keep support spacing at or below 1.0 m for 0.8–1.0 mm sheets and 1.2 m for 1.2 mm+. Larger spans need thicker profiles or a structural check.
