For architectural glazing projects, Baoding Sinhai Sunboard Manufacturing Co., Ltd. offers polycarbonate plug-in sheets, which are multi-wall thermoplastic panels. The panels are 30mm and 40mm thick and have an interlocking edge geometry, which allows them to join without the need for extra aluminium joining profiles. Impact resistance is up to 200 times that of glass according to conventional testing. UV co-extruded protective layers from 50 to 118 microns. Surface choices come in many colours with smooth, matte and anti-fog treatments. Sinhai is certificated with ISO 9001:2015, CE and RoHS, with 25 production lines in 3 manufacturing bases.
Also known as modular tongue and groove polycarbonate systems, these panels The interlocking edge design enables one panel to link directly into the next, minimising the need for vertical framing and external sealants.
This design handles numerous common problems on building sites:
This continuous transparent covering enables natural light to be transmitted while maintains structural integrity.

| Fire Performance | Self-extinguishing; compliant with EN 13501-1 B-s1, d0 / ASTM E84 Class A |
The 30mm and 40mm thickness choices span a variety of applications, from canopy structures to huge commercial curtain walls. In many typical arrangements the panels span the mid-span without extra support.
UV Co-extrusion technique attaches the protective layer directly into the panel surface during manufacturing and decreases the danger of peeling or surface damage over time.
Raw material grade may be chosen according to project needs and budget. Options include ordinary 100 percent virgin polycarbonate, premium imported SABIC or BAYER resin, or a bespoke material composition.
Sinhai carries out inspection at each level of manufacturing from raw material to final delivery. For polycarbonate plug-in sheets, the tests listed below are performed:
For large scale projects where a consistency across multiple panels is required the consistent dimensions and optical performance is especially important.
Industrial Facades: The panels offer lightweight wall covering for logistics centers and industrial facilities, meeting high wind load requirements and accommodating natural daylighting.
Sports Stadiums: The panel joints allow for thermal expansion over large temperature fluctuations, making them a realistic solution for stadium perimeters where regulated light dispersion is desired.
Commercial Atriums and Skylights The plug-in technology enables overhead glazing assemblies in inhabited areas with thermal insulation performance performance matching single-layer glass alternatives.
Curtain Walls, Canopies and Partitions Smooth or matte finishes as per light diffusion needs. Colour selections are available for a variety of architectural design needs.
This polycarbonate plug-in sheets series is available as OEM and ODM from Sinhai. A project manager is appointed to each order to coordinate requirements, timing and paperwork.
Customisation options provided:
With 25 production lines in 3 manufacturing locations and an annual output of over 60,000 tonnes, Sinhai is capable of supporting bulk orders, mixed containers and significant engineering projects.
Standard orders are filled in roughly 7 days. The Kashgar manufacturing base offers customers in Central Asia with a direct logistical channel delivering to most locations in the area in around 7 days.
Sinhai also has local storage resources in Tashkent and Dushanbe for customers with speedier regional fulfilment needs.
We have available shipping ways such as sea freight, truck transport and air shipment. The logistics staff also manages the customs clearance and cross-border documents.
Q1: How do the products deal with temperature changes?
A: Because the panels are flexible and have hidden connections, they can expand and contract within the plug joint. This lowers the chance of bending or cracking across the working temperature range of -40°C to +120°C.
Q2: Can these panels be used in curved building designs?
A: Yes. However, they can be cold-curved during installation as long as the bending radius is at least 150 to 200 times the thickness of the sheet that was chosen.
Q3: What stops water from getting into the tongue-and-groove joint?
A: The carefully planned interlocking geometry makes a capillary break that stops water from getting in without using wet sealants.
Q4: How long do these walls last?
A: SERVICE LIFE varies on how it was installed, the weather where it is, and how well it is taken care of. The co-extruded UV layer is meant to slow down the yellowing and loss of light transfer over time. Please get in touch with us to get warranty information that is specific to your situation.
Q5: Are they good for places where there is a high chance of fire?
A: The panels put out fires on their own and meet the fire performance requirements of EN 13501-1 B-s1, d0 and ASTM E84 Class A. During combustion, they give off very little smoke and no flaming droplets.
Q6: What grades of materials are there?
A: You can choose from 100% brand-new plastic, foreign SABIC or BAYER resin, or a mix of materials. The choice is based on the budget and performance requirements of the project.
