U-Lock polycarbonate is the most practical roofing panel for daylighting projects in 2026: it pairs glass-like light transmission with polycarbonate’s impact strength, in a lock-together profile that installs quickly and seals reliably. Here we cover the three applications our factory supplies most often — industrial factory skylights, carports and awnings, and swimming pool canopies.
1. Factory skylights and long-span roofs
Industrial roofs are the single largest use for U-Lock polycarbonate. By replacing dark roof sections with translucent panels, a factory floor is lit naturally during the day and artificial-lighting cost falls sharply. Wide 1040 mm panels with 20–30 mm rice-grain reinforced cores carry large purlin spans without sagging, while the double-hook lock profile keeps wind-driven rain out even on low-pitch roofs.

2. Carports, pergolas and shop entrances
For carports, pergolas and storefront awnings, the narrow 600 mm profile is the practical choice. Panels cold-bend to gentle curves (minimum radius 3–8 m), so a single smooth arc covers a parking bay with no mid-roof joints. The double-sided co-extruded UV layer keeps the sheets clear and slows yellowing through years of service.

3. Swimming pool canopies
Indoor pools need bright, even daylight without the corrosion problems of metal or the weight and breakage risk of glass. U-Lock polycarbonate panels over a pool canopy deliver diffused natural light while standing up to humid, chlorinated air. The translucent surface also softens glare over the water — a detail both swimmers and lifeguards prefer.

Why choose Jietai as your U-Lock supplier
As a manufacturer, we extrude U-Lock polycarbonate in our own factory and ship every project as a complete system — aluminium U-channel, I-beam purlins and EPDM gaskets included — so contractors get one matched source instead of mixing parts from different suppliers. Panels are cut to length, checked and packed before dispatch.

Frequently asked questions
What thickness of U-Lock polycarbonate do I need for a factory skylight?
For most factory daylighting strips, 8–16 mm twin-wall or four-wall panels are standard. Long-span and large-purlin roofs use 20–30 mm rice-grain reinforced panels for extra stiffness. Send us your span and wind load and we will recommend the right thickness.
Can U-Lock polycarbonate panels be curved?
Yes. U-Lock panels cold-bend to a minimum radius of 3–8 m, so they suit arched carports, canopies and vaulted roofs without heat forming.
How are U-Lock panels joined and kept watertight?
Panels lock together edge to edge and are held in an aluminium U-channel with EPDM gaskets on I-beam purlins. The double-hook profile (14 mm and above) resists wind uplift and keeps water out on low-pitch roofs.
What is the difference between U-Lock and interlocking polycarbonate panels?
U-Lock uses a raised U-shaped standing lock and is built for roofs and large-span daylighting. Interlocking panels use a tongue-and-groove joint and are aimed at facades and interior partitions. For any horizontal or curved roof, choose U-Lock.
How long does a U-Lock polycarbonate roof last?
With the double-sided co-extruded UV layer, U-Lock panels resist yellowing and hail impact for many years; multiwall polycarbonate roofing typically carries a 10-year light-transmission warranty.
