Match the sheet type to the roof, not only to the price

Polycarbonate roof panels are specified differently for pergolas, greenhouses, carports, skylights and industrial daylighting. The best choice depends on span, support spacing, light target, heat control, UV exposure and whether the installer needs a flat sheet, hollow sheet or corrugated profile.

Polycarbonate roof panels for greenhouse and daylight roofing

Multiwall polycarbonate sheet structures for roofing panels

Corrugated polycarbonate roofing sheet profile
Corrugated profileUseful for sheds, canopies and fast drainage.

Pergola roof panels

Use solid or corrugated panels when the buyer wants high clarity, easier cleaning and a lighter roof cover.

Greenhouse panels

Multiwall sheets help balance light transmission, insulation and panel stiffness for replacement or new builds.

Carport and canopy

Confirm support spacing, sheet overlap, fixing method and UV side before choosing thickness or profile.

Industrial skylight

For safety and daylighting projects, define impact risk, access frequency, cleaning method and any rating requirement.

Installation details buyers should confirm

Most roofing failures start with the wrong fixing details

Before pricing, Bakway reviews the roof size, support spacing, slope, expected load and sheet type. This helps avoid undersized panels, blocked thermal movement, wrong UV orientation or mismatched accessories.

Send roof dimensions for review
UV side and orientation

Confirm which side faces the sun. Incorrect orientation can shorten outdoor service life.

Thermal expansion gap

Polycarbonate moves with temperature. Holes, overlaps and fixing points need room for movement.

Support spacing

Span affects thickness choice more than sheet size alone. Share purlin or frame spacing if available.

Profile and accessories

Corrugated, solid and multiwall sheets use different overlaps, fasteners, tapes and edge closure details.

What to send for a roofing sheet quote

A roofing project quote depends on more than sheet type. Send the span, support spacing, climate exposure and installation method so Bakway can review thickness, UV side, profile and packaging before pricing.

  • Quantity, destination country, packaging and sample requirement.

Polycarbonate Roofing Sheets — Buyer FAQ

What thickness of polycarbonate roofing sheet do I need?

It depends on span and load, not only roof type. As a starting point: corrugated 0.8–1.5 mm for sheds and carports, multiwall 6–10 mm for pergolas and greenhouses, 16–25 mm multiwall where insulation matters. Send purlin spacing and expected wind/snow load and we confirm thickness before quoting.

How long do polycarbonate roofing sheets last outdoors?

Specified UV-protected outdoor sheets may carry a written warranty of up to 10 years, subject to product, installation and environment terms. With the UV side facing the sun and correct fixing details, typical outdoor service life is well beyond the warranty period.

What sheet sizes can you produce?

Standard width is 2,100 mm for solid and multiwall sheets; corrugated profiles follow fixed profile widths. Length is cut to order within container limits. Custom widths are possible at volume — share your cutting list for a yield check.

What is the MOQ and production lead time?

The MOQ is 1 metric ton for this supply route. Final availability and order details are confirmed against the project specification.

Which colors are available?

Clear, opal/white, bronze, blue, green and grey are standard; heat-control and custom colors can be matched at volume. Light transmission targets should be confirmed together with color and structure.

Is polycarbonate roofing resistant to hail?

Polycarbonate has roughly 200× the impact strength of glass and stays impact-resistant from −40 °C to +120 °C, which is why it is specified for hail-exposed roofs, skylights and safety glazing.

What thickness polycarbonate should I use for a carport roof?

Choose it from the purlin spacing, not the roof area. 6 mm twin-wall spans 800–900 mm between purlins and suits a general carport; 10 mm spans 1,000–1,100 mm and is the usual pick where snow is occasional; in 50-year snow above 1.5 kPa step up to 16 mm triple-wall or reduce the spacing. Corrugated 0.8–1.5 mm is the lightest and cheapest option for open carports and sheds in mild climates.

Do you supply sheet material for carport roofs?

Bakway supplies polycarbonate roof sheet material for carport projects. We do not supply carport kits, installation, pre-drilling or cut-to-bay services. Send the roof type, support spacing, required sheet type, colour, destination and quantity so the material specification can be confirmed before quotation.
