Growers choose glazing materials based on three factors: how well they insulate, how long they last, and how much light they let through. Polycarbonate sheet for greenhouse covers all three. These hollow and curved panels are made from 100% fresh Bayer/Sabic PC resin and have a 50εm co-extruded UV layer. They are perfect for business food production, flower houses, plant facilities, and research centers that need to keep working well all year.
Compare to glass or polyethylene film, polycarbonate sheet for greenhouse is strong, lightweight, and predictable light management. For flexible curved or single-span frames, corrugated frames are excellent, whereas hollow twin-wall and multi-wall designs trap air for thermal insulation.
Multi-wall, twin-wall, and solid panels are available. Your surroundings, crop type, and frame design define the ideal insulation, light transmission, and load-bearing format.

Impact Strength and Weather Resistance
These panels can survive hail, snow, and severe winds year-round because to their 850 J/m impact strength. The product works effectively in cold winters and hot summers without twisting or breaking from -40°C to +120°C.
Providing UV defence
Approximately 98% to 100% of ultraviolet radiation below 380nm is covered by the 50µm co-extruded UV This prevents the layer from yellowing, fracturing, and reducing light transmission. ASTM D1003 testing require panels to lose less than 6% light transmission after 10 years. Install with the UV-protected side out for optimal results. The protective film is marked to assist you place.
Self-Draining Coating
Water-loving anti-drip coating reduces interior surface tension. Condensation generates a thin layer that flows into gutters. Keeping leaves dry during temperature fluctuations reduces bacterial attacks.
Light Passage
These panels permit up to 90% of light through, allowing plants to absorb PAR. In seedling homes and study spaces, the thin wall construction distributes incoming light, decreasing points and illuminating the upper layers evenly.
Fire Rating
The B1 grade under GB 8624 and V-2 certification under UL94 make this substance self-extinguishing. It may melt under direct heat, but the panel won't catch fire.
Framework Compatibility
Steel, aluminium, and wood structures fit panels. Sheets up to 2.5 m wide need fewer gap joints. This prevents water entry and simplifies installation. Orders include node design blueprints with sealing features and screw arrangement instructions.
An yearly output of more than 60,000 tonnes is made by Baoding Sinhai Sunboard Manufacturing Co., Ltd., which has three production sites with more than 25 production lines. OEM and ODM services are available. There are options for thickness, colour, surface finish, panel size, UV layer configuration, and film coating. For customised needs, CNC cutting, special-shaped cutting, bending, and thermoforming are all options.
Usually, standard orders are finished in about 7 days. Regional warehouses in Tashkent and Dushanbe help with delivery to countries like Uzbekistan and Tajikistan from the Kashgar production base. Shipping choices include by sea, truck, or air.
More than aluminium, polycarbonate sheet for greenhouse has a thermal expansion coefficient of about 0.065 mm/m°C. Oversize holes should be pre-drilled, and EPDM seals should be used to allow for about 3mm/m of movement. By doing this, the screen won't buckle when the temperature changes.
All orders come with node design drawings, sealing information, and expansion-gap plans. For qualifying bulk orders, on-site support can be set up, and remote installation help is available.
Q: Which thicknesses and widths are available?
A: Hollow panels are 4–10mm thick and corrugated sheets 0.75–3.0mm. Maximum width 2.5m; length custom-cut. Included are full node drawings.
Q: Are these panels suitable which greenhouses?
A: Commercial vegetable, flower, and seedling greenhouses, eco-restaurants, agri-tourism, and research institutions. Starting with 4–16mm twin-wall or transparent solid panels works for most growth situations.
Q: How does anti-drip coating work?
A: Because the hydrophilic inner coating decreases surface tension, condensation creates a thin draining film rather than droplets. This avoids water from hitting plants and decreases fungal danger.
Q: Will panels yellow?
A: According to ASTM D1003, the 50μm co-extruded UV layer maintains light transmission loss below 6% for 10 years. To avoid yellowing throughout the warranty, 98%–100% UV blocking is used.
Q: How should installation thermal expansion be managed?
A: Allow 3mm/m movement with pre-drilled larger holes and EPDM glazing gaskets. This is the typical method for preventing polycarbonate's 0.065 mm/m°C expansion-induced buckling.
Q: Are these panels suited for tropical or high-altitude climates?
A: The UV-stabilized grade with 98%–100% anti-UV rate performs well in high-altitude and tropical growth locations with increased sun radiation.
