Corrugated Polycarbonate Roofing Sheets
HSQY PLASTIC manufactures and supplies corrugated polycarbonate sheets for roofing, skylights, rooflights, greenhouses, canopies, agricultural buildings, industrial warehouses, commercial sheds, public facilities and daylighting systems.
Also known as corrugated PC roofing sheets, profiled polycarbonate sheets, clear plastic roofing panels, wave polycarbonate sheets or polycarbonate rooflight panels, these sheets combine the impact resistance of polycarbonate with a profiled shape that improves rigidity and allows the panel to integrate with suitable roof systems.
HSQY's current corrugated polycarbonate range covers approximately 0.7–3.0 mm thickness. Common current widths include approximately 840 mm, 900 mm and 1050 mm, while sheet width, length, corrugation profile and color can be customized according to roofing-system requirements.
The most important parameter for many industrial roofing projects is not thickness alone but the corrugation profile. Pitch, wave height, crown width, valley shape and effective cover width must be compatible with the surrounding roof panels and fixing system.
What Is a Corrugated Polycarbonate Sheet?
A corrugated polycarbonate sheet is a single-wall polycarbonate panel formed into a repeating wave, rib or roofing profile rather than remaining completely flat.
Forming the sheet into a corrugated profile increases rigidity compared with a flat sheet of similar thickness and creates overlapping edges that can be incorporated into suitable roofing and cladding systems.
Clear grades are particularly useful where the roof needs natural daylight, while tinted and opaque colors can reduce brightness or provide a different architectural appearance.

Corrugated Profile Matching for Roofing Projects
Profile matching is one of the most important purchasing requirements for corrugated polycarbonate roofing.
Two sheets can have the same nominal width and thickness but still be incompatible if their corrugation pitch, crown height, valley width or side-lap geometry are different.
This is particularly important when transparent polycarbonate rooflights are installed between existing metal roofing, steel panels or fibre-cement roofing sheets.
For replacement or profile-matching projects, send HSQY one of the following:
Existing roofing-sheet sample
Cross-section technical drawing
Profile manufacturer and profile code
Corrugation pitch
Wave or rib height
Crown and valley dimensions
Overall sheet width
Effective cover width
Side-lap configuration
Overall Width vs. Effective Cover Width
Buyers should distinguish between overall sheet width and effective cover width.
Overall width is the physical edge-to-edge sheet width. Effective cover width is the roof width actually covered after the required side overlap is made.
Using overall width instead of effective cover width when calculating quantities can result in insufficient roofing material.
Always confirm the effective cover width for the exact corrugated profile before calculating the number of sheets required.
Common Corrugated Polycarbonate Profiles
| Profile Type | Main Characteristic | Typical Use |
| Wave / Sinusoidal Type | Smooth repeating curved waves | Greenhouses, canopies, general roofing and agricultural buildings |
| Trapezoidal / Ribbed Type | Defined flat crowns and valleys with straighter rib geometry | Industrial roofing, warehouses and profile matching with metal roofs |
| Custom Profile | Developed to reproduce an existing roof cross-section | Replacement rooflights, proprietary roofing systems and OEM projects |
Profile names and dimensions are not globally standardized. A profile described as "wave" or "trapezoidal" by two suppliers may still have different dimensions, so drawings should be compared before ordering.
Corrugated Polycarbonate for Industrial Rooflights
Clear corrugated polycarbonate can be incorporated into suitable industrial roofing systems to create rooflights that introduce natural daylight into warehouses, factories, workshops and agricultural buildings.
In this application, matching the polycarbonate profile to surrounding metal or fibre-cement sheets is especially important for overlap, fixing and weather-sealing performance.
Provide the existing roofing profile, purlin spacing, roof slope and required daylight area when requesting rooflight material.
Corrugated Polycarbonate for Greenhouses
Clear corrugated PC sheet can be used for greenhouse roofing where natural light, rain protection and impact resistance are required.
Single-wall corrugated polycarbonate is normally selected where high daylight transmission and lightweight construction are priorities.
Where thermal insulation is more important, buyers should also compare Multiwall Polycarbonate Sheets, because their internal air chambers provide greater insulation than a single-wall corrugated sheet.
Corrugated Polycarbonate for Canopies and Walkways
Corrugated PC roofing can be used for entrance canopies, patios, covered walkways, parking shelters, bus shelters, station roofs and other weather-protection structures.
Clear panels maximize daylight, while smoke grey, blue, green, brown and milk-white options can be considered when reduced brightness or architectural color is desired.
Corrugated Polycarbonate for Agricultural Buildings
Agricultural applications include greenhouses, livestock buildings, fish sheds, equipment shelters and farm structures requiring weather protection and daylight.
Chemical exposure from cleaning agents, fertilizers, pesticides or animal environments should be reviewed when selecting roofing and sealing materials because chemical compatibility depends on the actual substance and concentration.
Clear vs. Colored Corrugated Polycarbonate
| Color Type | Main Priority | Typical Applications |
| Clear | Maximum natural daylight for the selected grade | Rooflights, greenhouses, skylights and industrial daylighting |
| Smoke / Grey / Brown | Reduced visible brightness and tinted appearance | Canopies, patios, commercial entrances and architectural roofing |
| Blue / Green | Decorative colored daylighting | Greenhouses, shelters, pools, canopies and architectural roofs |
| Milk White / Opal-Type Appearance | More diffuse daylight and reduced direct visibility | Commercial roofing, walkways and diffuse daylighting |
How to Choose Corrugated Polycarbonate Thickness
Sheet thickness affects rigidity, impact performance, handling and cost, but it should never be used as the only structural-design parameter.
| Thickness | General Selection Consideration |
| 0.7–1.0 mm | Lightweight roofing applications with appropriate profile geometry and close support spacing |
| 1.2–1.5 mm | General greenhouse, canopy, skylight and roofing applications subject to structural design |
| 2.0 mm | Projects requiring greater sheet gauge and rigidity; HSQY currently offers a dedicated 2 mm roofing product |
| 2.5–3.0 mm | Heavier-gauge project applications where profile, span and loading have been evaluated |
Structural suitability depends on profile geometry, purlin spacing, wind load, snow load, roof pitch, fixing method and local building requirements.
UV-Protected Corrugated Polycarbonate Roofing
Outdoor polycarbonate roofing should use a suitable UV-protected grade.
A UV-resistant surface helps reduce yellowing and deterioration caused by prolonged exposure to sunlight.
If UV protection is provided on only one side of the sheet, that protected surface must face the sun. Check the protective-film printing or product identification before installation.
Corrugated Polycarbonate vs. Multiwall Polycarbonate
| Feature | Corrugated Polycarbonate | Multiwall Polycarbonate |
| Structure | Single-wall profiled sheet | Hollow cellular sheet with internal ribs |
| Main Strength | Profile compatibility, daylighting and lightweight roofing | Thermal insulation and lightweight glazing |
| Thermal Insulation | Limited because there are no internal insulating chambers | Better due to enclosed air chambers |
| Roof Profile Matching | Excellent for matching profiled metal or fibre-cement roofing | Usually installed with dedicated glazing/profile systems |
| Typical Use | Rooflights, warehouses, sheds, greenhouses and canopies | Greenhouses, insulated roofs, skylights and translucent facades |
Corrugated Polycarbonate vs. Solid Polycarbonate
| Feature | Corrugated PC Sheet | Solid PC Sheet |
| Shape | Pre-profiled wave or rib structure | Flat solid panel |
| Main Roofing Advantage | Direct integration into compatible profiled roofing systems | Better suited to flat glazing, guards and fabricated panels |
| Fabrication | Profile already formed during manufacturing | Can be cut, bent and thermoformed into custom shapes |
For flat glazing, machine guards and transparent panels, review our Solid Polycarbonate Sheets.
Corrugated Polycarbonate vs. Metal Roofing
Polycarbonate and metal roofing are often used together rather than treated only as competing materials.
| Feature | Corrugated Polycarbonate | Metal Roofing |
| Natural Light | Clear and translucent grades allow daylight | Normally opaque |
| Corrosion | Polycarbonate does not rust | Corrosion performance depends on metal and coating system |
| Thermal Expansion | Requires significant allowance for movement | Also expands but at a different rate |
| Common Combined Use | Transparent rooflight sections | Main opaque roofing area |
How to Install Corrugated Polycarbonate Roofing
Install the UV-Protected Surface Facing the Sun
Where the product has one-sided UV protection, identify the protected surface from the product markings and install that face toward exterior sunlight.
Run Corrugations Up the Roof Slope
Corrugations should normally run from the higher point of the roof toward the eaves so rainwater can drain along the profile.
Use the Correct Roof Pitch
A roof requires sufficient slope for reliable rainwater drainage. Minimum slope depends on the sheet profile, overlap, roof length and roofing system, so follow the approved profile drawing or project specification rather than using one universal pitch.
Allow for Thermal Expansion
Polycarbonate expands in hot conditions and contracts when temperatures fall. Fixing holes and sheet-edge clearances must allow the panel to move without excessive stress.
Do Not Overtighten Fasteners
Overtightening screws can restrict thermal movement and create concentrated stress around fixing points. Fasteners and washers should secure the sheet while allowing the designed movement of the roofing system.
Use Compatible Washers and Sealants
Roofing washers, sealants, tapes and coatings that contact the sheet should be compatible with polycarbonate.
Avoid assuming every PVC-based, solvent-containing or bituminous product is chemically compatible with polycarbonate. Confirm compatibility before installation.
Follow the Correct Side and End Overlap
Required side lap and end lap depend on the corrugated profile, roof slope, sheet length, wind exposure and roofing-system design.
Confirm the overlap detail before ordering because it directly affects effective cover width and total sheet quantity.
Fix at the Correct Position on the Profile
Fixing position can vary between roofing profiles and support systems. Many profiled roof systems use crown or crest fixing, but the approved drawing for the exact sheet profile and roofing system should always take priority.
Cutting and Drilling Corrugated Polycarbonate
Corrugated polycarbonate sheets can be cut using suitable fine-tooth saws and other plastic-sheet cutting equipment.
Support the sheet properly during cutting to reduce vibration and protect the corrugation from local deformation.
When drilling, holes should provide appropriate clearance for thermal movement rather than tightly gripping the screw shank.
Keep protective film on the sheet during fabrication where practical and remove chips before final installation.
3 m vs. 5 m Corrugated Polycarbonate Sheets
| Length | Main Consideration |
| 3 m | Easier handling and transportation for smaller canopies, greenhouses and roof sections |
| 5 m | Can reduce the number of end joints on longer roof slopes but requires greater attention to transport, handling and thermal movement |
| Custom Length | Can reduce cutting waste and unnecessary overlaps when production and shipping conditions allow |
Is Corrugated Polycarbonate Waterproof?
Polycarbonate itself is not damaged by normal rainwater exposure, but a completed roof should not be described as waterproof based only on the sheet material.
Weather-tight performance depends on roof pitch, profile matching, side and end overlaps, flashing, fasteners, washers, sealants, support alignment and installation quality.
Roof projects should therefore be evaluated as a complete roofing system rather than assuming that any corrugated PC panel will prevent leakage under every installation condition.
Wind, Snow and Hail Performance
Polycarbonate is selected for roofing partly because of its high impact resistance, but roof performance under wind, snow and hail depends on more than the base resin.
Profile geometry, thickness, purlin spacing, fastener spacing, sheet length, edge conditions and structural support all influence the finished roof.
If the project has defined wind-load, snow-load or impact requirements, provide those design values so the appropriate sheet and support arrangement can be evaluated.
Can You Walk on Corrugated Polycarbonate Roofing?
Do not walk directly on corrugated polycarbonate roofing sheets.
Roof work should use appropriate crawling boards, walkways, ladders, fall-protection systems and structural supports in accordance with applicable safety procedures.
The fact that polycarbonate has high impact resistance does not mean an unsupported roofing panel is designed to be used as a walking surface.
Fire Performance of Corrugated Polycarbonate
Fire performance depends on the exact polycarbonate formulation, sheet thickness, profile and test standard.
A fire classification from one polycarbonate product should not automatically be applied to the complete corrugated PC range.
If your project requires UL 94, EN 13501, a local building-code classification or another fire test, include the exact standard and required class when requesting a quotation.
Cleaning and Maintenance
Clean corrugated polycarbonate using clean water, mild soap or a compatible neutral detergent together with a soft cloth or sponge.
Avoid abrasive pads and aggressive solvents that have not been confirmed as compatible with the polycarbonate resin or UV-protected surface.
Periodically inspect fasteners, washers, sealants, overlaps and flashing, particularly after severe weather.
How to Choose Corrugated Polycarbonate Roofing Sheets
1. Define the Roofing Application
Specify whether the sheet will be used for an industrial rooflight, greenhouse, canopy, skylight, warehouse, agricultural building or public shelter.
2. Confirm the Corrugated Profile
Provide an existing sample or profile drawing showing pitch, height, crown, valley and overlap dimensions.
3. Confirm Overall and Effective Width
Use effective cover width when calculating roof quantity because part of the overall width is consumed by side overlap.
4. Select Sheet Thickness
HSQY's current range includes approximately 0.7–3.0 mm. Final thickness should consider profile geometry, support spacing and loading.
5. Select Clear or Colored Sheet
Choose clear for maximum daylight or tinted/opaque options where shade, privacy or architectural appearance is more important.
6. Confirm UV Protection
Outdoor roofing should use a suitable UV-protected grade, with the protected surface installed toward sunlight.
7. Provide Roof Pitch and Purlin Spacing
Roof slope and support spacing influence water drainage, deflection and load performance.
8. Provide Wind and Snow Loads
Structural projects should include applicable design loads or location-specific engineering requirements.
9. Confirm Sheet Length and Overlaps
Longer sheets can reduce end overlaps but create greater transport, handling and thermal-movement requirements.
10. Confirm Fasteners and Accessories
Specify washers, fasteners, flashing, sealing tape and other components that will contact the polycarbonate.
11. Approve a Sample or Profile Drawing
For profile-matching projects, confirm the physical sample or cross-sectional drawing before bulk production.

Corrugated Polycarbonate Sheet Quality Control
Important inspection and approval parameters can include:
Sheet thickness and tolerance
Overall width
Effective cover width
Sheet length
Corrugation pitch
Wave or rib height
Profile geometry
Side-lap compatibility
Color consistency
Light transmission where specified
UV-protected surface
Visual surface quality
Impact performance where specified
Fire classification where specified
Protective-film condition
Packing and pallet condition
Packing and International Shipping
Corrugated polycarbonate sheets are lightweight but occupy significant volume, so sheet length, nesting profile, pallet design and container loading should be considered when comparing landed cost.
Protective film and suitable wrapping can help reduce scratches during handling and transportation.
Custom sheet lengths may help reduce site cutting and end overlaps, but they should also be checked against container length, unloading equipment and installation handling requirements.

What widths are available?
Current HSQY products include widths around 840, 900 and 1050 mm, while custom widths are available for suitable projects.
What is effective cover width?
Effective cover width is the actual roof width covered by one sheet after the required side overlap is made. It is normally smaller than the overall physical sheet width.
Can HSQY match my existing metal roofing profile?
HSQY offers multiple corrugated profiles and can evaluate custom profile development. Provide a physical roof-sheet sample or cross-sectional drawing for comparison.
Can corrugated polycarbonate be installed with metal roofing?
Yes, transparent corrugated polycarbonate can be incorporated as rooflight sections in suitable metal roofing systems when the profiles, overlaps, support and fixing details are compatible.
How much light does clear corrugated polycarbonate transmit?
Suitable current HSQY clear products list light transmission above approximately 85%. Actual transmission depends on thickness, profile, surface and color.
Is corrugated polycarbonate UV resistant?
UV-protected outdoor grades are available. Confirm whether protection is provided on one or both surfaces and install the protected side toward sunlight where applicable.
Which side faces the sun?
Where UV protection is one-sided, the marked UV-protected surface must face toward exterior sunlight. Check protective-film markings before installation.
Is corrugated polycarbonate waterproof?
The material withstands normal rain exposure, but roof weather-tightness depends on correct profile matching, roof pitch, overlap, flashing, washers, sealants and installation.
What roof pitch is required?
Minimum roof slope depends on the corrugated profile, overlap arrangement, roof length and roofing-system specification. Use the approved installation detail for the exact product rather than one universal angle.
How much should corrugated sheets overlap?
Side and end overlap depend on profile geometry, roof slope, wind exposure and roofing-system design. Confirm overlap before calculating effective cover width and sheet quantity.
Where should screws be installed?
Fastener location is profile-specific. Follow the approved roofing-system drawing. Many profiled systems use crown fixing, but this should not be assumed for every profile.
Why do fixing holes need clearance?
Polycarbonate expands and contracts with temperature. Proper hole clearance allows the sheet to move and reduces stress around the fasteners.
Can I overtighten roofing screws?
No. Excessive tightening can restrict thermal movement and create local stress or deformation. Fasteners should follow the approved roofing-system installation method.
Can corrugated polycarbonate be cut?
Yes. Suitable fine-tooth saws and plastic-sheet cutting equipment can be used. Support the corrugations during cutting to reduce vibration.
Can corrugated polycarbonate be drilled?
Yes. Drilling should use suitable tools and provide enough clearance around the fastener for thermal expansion.
Can you walk on corrugated polycarbonate roofing?
Do not walk directly on polycarbonate roofing sheets. Use proper crawling boards, ladders, walkways and fall-protection equipment supported by the roof structure.
Is corrugated polycarbonate good for greenhouses?
Clear corrugated polycarbonate can be suitable where high daylight, impact resistance and lightweight roofing are priorities. For improved thermal insulation, compare it with twinwall or multiwall polycarbonate.
Is corrugated polycarbonate better than multiwall sheet?
Neither is universally better. Corrugated PC is advantageous for profiled roofing and rooflight integration, while multiwall PC provides better thermal insulation through its internal air chambers.
Does HSQY offer 2 mm corrugated roofing sheet?
Yes. HSQY currently lists a dedicated 2 mm clear corrugated polycarbonate roofing product with 3 m and 5 m featured lengths, subject to final order confirmation.
