Polycarbonate Accessories U profile from Baoding Sinhai Sunboard Manufacturing Co., Ltd. covers the open edges of solid and multiwall PC sheets. The profile is made of 100% virgin PC resin with a co-extruded UV-protective layer of at least 50 microns, is suitable for sheet thicknesses from 4 mm to 20 mm. Standard lengths: 2.1m, 5.8m, 6m, trimming to size available. The colors are translucent, copper, gray, blue.
A polycarbonate U profile is a thermoplastic end-cap that is precisely extruded and used to seal the raw edges of solid polycarbonate panels or the open flutes of multiwall PC sheets.
Dust, insects, and moisture may penetrate the interior cells of exposed sheet ends if the edges are not sealed. Algal development, decreased thermal insulation, and noticeable discolouration at the panel edge result from this over time.
By producing a tight mechanical seal that prevents water intrusion and airborne particles while yet allowing the sheet to expand and contract in response to temperature changes, the U profile solves these issues.
The profile shares the same coefficient of thermal expansion as the polycarbonate sheet it protects. This compatibility reduces structural stress and eliminates vibration noise during daily temperature shifts — a common issue when aluminum edges are used instead.

Each polycarbonate accessories U profile is inspected in four stages before leaving the manufacturer.
UV Layer Thickness Verification: Microscopic examination reveals a minimum of 50 microns of the co-extruded UV layer over the whole length of the profile. This protects the surface from fading and becoming brittle under outside exposure for a lengthy period.
Dimensional Precision Testing Calliper testing to ensure all tolerances are within ±0.05 mm. This exact fit eliminates vibration noise and water leaks at the border of the sheet.
Accelerated Weathering (ASTM G154): Profiles are exposed to UV and moisture cycles . The yellowing index and tensile strength retention are tested for long-term performance.
Impact resistance testing: Falling dart and Izod impact testing verify that the profile will not shatter under mechanical stress when installed in cold conditions.
Commercial Greenhouses: With high humidity, the open edges of the sheets encourage algae development within the flutes. The U-profile closes the ends of the cell, safeguarding the interior microclimate and increasing the service life of glazing panels.
Architectural Skylights And Canopies The profile gives a weather-tight finish at the margins of sheets, able to cope with wind loads and snow buildup, as well as accommodate heat circulation – critical for large-span roofs.
Industrial Sound Barriers and Partitions Polycarbonate panels in outdoor or industry locations are exposed to chemicals and mechanical deterioration. The U-profile shields the rough edge on both sides.
Patio Covers, Pergolas and Awnings: The profile is easy to install on smaller structures and has colours to match the ordered panels.
For Polycarbonate accessories U profile, Sinhai provides OEM and ODM orders. On request we may handle non-standard lengths, special colour matching and branded items.
Colour homogeneity between the panel and the profile is a practical concern for conspicuous installations. All four colours (transparent, copper, grey and blue) are available on the whole PC sheet assortment.
The warehouse has transparent profiles in stock, which means reduced lead times on regular orders. The Kashgar manufacturing base can supply goods to Central Asian markets in around 7 days.
With sheets, H-type joiners, U-type end-caps, F-snaps and hardware accessories, we give you a full PC system from one source. This eliminates worries about component compatibility and eases the coordination of purchase.
The business was one of the key drafting bodies for the China National Standard for Polycarbonate Sheets, which took effect on April 1, 2025. ISO 9001:2015, CE, RoHS and UDEM certifications accompany the products.
The plant has 286+ personnel, 25+ manufacturing lines, and a yearly output of 60,000+ tonnes. It caters to major engineering orders, mixed-container procurement, and smaller OEM runs at the same time.
Q: What sheet thicknesses does the U profile fit?
A: The profile fits sheet thicknesses from 4 mm to 20 mm, covering most standard multiwall and solid polycarbonate panels.
Q: Are custom colors available?
A: Transparent, bronze, grey, and blue are standard. Color matching to your ordered panels is also available on request.
Q: Can profiles be cut to non-standard lengths, such as 5 m?
A: The standard stock length is 6 m. A cutting service is available to supply 5 m lengths or other custom dimensions when required.
Q: Is stock available for immediate shipment?
A: Transparent U profiles are held in warehouse stock. Other colors may require a short production lead time depending on order volume.
Q: Can the U profile follow a curved roof structure?
A: Yes. The profile can cold-bend to follow the minimum bending radius of the corresponding polycarbonate sheet, making it suitable for curved canopy and skylight applications.
