Manufactured by Baoding Sinhai Sunboard Manufacturing Co., Ltd., our high-quality u lock polycarbonate sheet is produced across 3 production bases with 25+ production lines and an annual output of 60,000+ tons. Available in 8–16mm thickness using 100% virgin resin or SABIC/BAYER material, every panel undergoes 100% thickness and UV layer inspection before shipment. The co-extruded UV protection layer ranges from 50 to 117 microns, and the B1 fire rating meets EN 13501-1 (B-s1, d0).
A high-quality u lock polycarbonate sheet is an architectural glazing system built around a standing-seam profile. Polycarbonate or aluminum connectors join panels through an upright "U"-shaped rib, so no screws penetrate the panel surface.
This approach addresses three practical problems contractors encounter on roofing projects:
The standing seam also eliminates visible fasteners on the roof surface, which matters for both aesthetics and long-term weatherproofing.
The multi-wall internal structure — available in X-structure, honeycomb, or rectangular cell configurations — contributes to the sheet's thermal insulation performance, with U-values reaching as low as 1.0 W/m²K depending on configuration and thickness.
Core physical parameters are listed below:
| Property | Value |
|---|---|
| Thickness | 8–16mm (customizable) |
| Light Transmittance | Up to 80% (varies by thickness and color) |
| Impact Resistance | 200× stronger than glass |
| Operating Temperature | -40°C to +120°C |
| UV Co-extrusion Layer | 50–117 microns (1 or 2 faces) |
| Yellowing Index | Delta E < 5 over 10 years |
| Fire Rating | B1 grade (EN 13501-1 B-s1, d0) |
| Material Options | 100% virgin resin / SABIC / BAYER |
| Colors Available | Transparent, Bronze, Grey, Opal, Lake Blue, Amber, Dark Blue, Silver, Orange, Yellow, or custom |
| Certifications | ISO 9001:2015, CE, RoHS, UDEM |
The operating range of -40°C to +120°C covers both extreme cold climates and high-heat environments, making the sheet suitable for a wide range of geographic markets.
Before leaving the factory, every high-quality u lock polycarbonate sheet undergoes a series of checks.
Verification of UV Layer Thickness—a tiny cross-sectional study shows that the UV co-extrusion layer is the same all the way across the width of the panel.
Impact Strength Testing—using the falling dart method according to ISO 6603, which simulates the effects of snow to check the resistance's performance.
Dimensional Tolerance Check: The 'U' hook shape is tested to make sure it fits correctly with the sockets. This keeps air from getting in at the joints.
Accelerated Weathering Tests—The ASTM G154 protocol is used to check how long-lasting yellowing and weakening are when UV light is applied.
Loading Capacity Tests: The deflection under positive pressure and suction is checked against the building code.
Before they leave the factory, all panels, not just a sample batch, are checked for thickness and UV layer.
Industrial skylights and northlights: the standing seam keeps a smooth, watertight surface over large areas, which is useful in buildings that get a lot of rain or snow.
Commercial Architectural Facades: The surface of the translucent panel makes building envelopes that are lit up without any visible fasteners, giving architects a clean look for the outside.
For public buildings and sports stadiums with high roofs, it's important that the roofs can fight wind lifting and heat movement.
Greenhouses and Canopies: 8 mm thick panels are best for lighter shade structures, while 16 mm thick panels are best for heavy awning loads.
Coastal Environments: The drill-free U-lock connector system gets rid of the metal fastener contact points that can rust in saltwater.

Overseas warehouse resources in Tashkent and Dushanbe provide regional customers with local delivery options. Shipping is supported by sea, truck, and air freight, with experienced teams handling customs clearance and cross-border documentation.
Q1: Does the U lock mechanism lessen polycarbonate roof clicking noise?
A: Yes. Fixed-screw systems make friction noise, while the U-lock design lets panels glide inside connections during thermal expansion.
Q2: Do these sheets cold-curve for arched roofs?
A: We advocate cold-curving. Before fabrication, verify project requirements and the minimum bending radius is 150 to 200 times sheet thickness.
Q3: How does the system manage wind rise?
A: Standing seams form a roof-wide structural rib. When used with stainless steel or aluminium clips, this setup resists pull-out better than screw-fix. Specific load levels depend on clip spacing and local code.
Q4: This sheet's materials?
A: The panels are made from 100% virgin polycarbonate or imported SABIC or BAYER resin. Request custom material.
Q5: Do I need specific maintenance?
A: Maintenance is low. Light transmission is best maintained by annual mild soap and water cleaning.
Q6: Service life averages?
A: Premier UV co-extrusion panels have a 10-year guarantee. Climate, installation, and maintenance affect service life.
