Honeycomb PC sheet is a multi-wall polycarbonate panel with a hexagonal interior structure, which has the same geometry as a beehive in nature. Unlike typical twin-wall or hollow sheets, the hexagonal matrix distributes stress and impact from many directions at once, offering a measurable increase in panel stiffness at the same thickness. It is produced by Baoding Sinhai Sunboard Manufacturing Co., Ltd. The company is a direct producer, with over 30 years’ expertise in polycarbonate, three production bases and over 25 manufacturing lines. This panel is developed for demanding construction and industrial applications.
Hollow PC panels are generally provided with vertical ribs in one direction which makes them suitable for loading in just one axis. In a honeycomb polycarbonate panel the hexagonal lattice distributes load and impact along the whole cell network, rather than along straight lines.
That means in practice better resistance to hail, wind uplift and snow buildup – without a corresponding increase in weight. This format’s structural balance is the key differentiator for customers comparing structural glazing materials to traditional multi-wall sheets.

The hexagonal air pockets within the panel are sealed on both sides so that the convective heat transmission is limited better than open channel rib constructions. The K-value of the 16 mm unit may go down to 1.1 W/m²K, a factor that is important for projects in cold climate markets with stringent building energy requirements.
For architects and builders designing energy efficient buildings, lower thermal transmittance equals lower heating and cooling loads throughout the building’s service life. This performance advantage over the typical hollow-sheet forms is a direct result of the sealed-cell shape.
Commercial Skylights and Roofing
The strong strength to weight ratio enables for greater structural spans with less steel support beneath. The panel is reliable under large snow loads and wind pressure, and may be used in commercial roof glazing projects where structural performance and daylighting are both needed.
Premium Greenhouses for Farming
Hexagonal cells distribute incoming light more uniformly across plant canopies than smooth-surfaced panels, minimising hot spots while retaining heat. This combination provides uniform growth conditions in cold climatic areas.
Sound Insulation & Interior Partitions
The cellular structure decreases the sound propagation by up to 21-23 dB. The panel is intended for workplace partitions when a geometric aesthetic, practical acoustic isolation and diffused natural light are all needed at the same time.
Noise Barriers on Roads
The complex interior geometry of Honeycomb PC sheet scatters sound waves in a way that is distinct from flat or ribbed panels, making it a useful solution for infrastructure acoustic applications where increased STC performance is required.
All panels leave the factory with a co-extruded UV protection film of between 50 and 111 microns on one or two sides. This layer is not a surface coating added post-production but is fused into the sheet during the extrusion process, therefore it is not reliant on a separate bonding procedure to achieve adherence.
The service temperature range from −40 °C to +120 °C covers the conditions seen in Central Asian winters and Middle Eastern summers. Thus, the panel may be deployed over a broad variety of climatic zones without the need for special-grade variations.
The 5 quality standards below offer the clearest view of real panel consistency when assessing honeycomb polycarbonate sheet suppliers:
Baoding Sinhai performs these tests during raw material receipt, throughout manufacturing and at final delivery inspection.
Panels are available in conventional sizes or OEM/ODM designs. The processing choices include CNC cutting, bending, special-shaped cutting, edge sealing and customised film coating. More than 70 free moulds provide profile and accessory possibilities. Supports OEM logo printing on PE protective film, which is beneficial for distributors to set up their own product identity.
All panels of Honeycomb PC sheet are supplied with a PE protective covering on both sides and strapped to hardwood pallets to avoid surface damage during transport. Sea, truck and air transport including paperwork management for customs clearance and cross border delivery.
The Kashgar manufacturing base supports the Central Asian nations with faster transit times to the Central Asian markets. “We have warehouse resources in Tashkent and Dushanbe to make the lead times shorter for regional buyers.
Q1: Is "Honeycomb" just a marketing name, or does the structure actually perform differently?
A: The hexagonal matrix distributes weight and impact across the full cell network rather than along single-direction ribs. This produces measurably higher multi-directional rigidity compared to standard twin-wall formats, which is why the panel is specified for hail-exposed and high-wind roofing projects.
Q2: Can this panel be used for indoor office partitions?
A: Yes. The panel is used for interior partitions where a geometric visual effect, diffused daylighting, and acoustic separation between spaces are all needed. The 21–23 dB sound reduction figure applies in these configurations.
Q3: Does the hexagonal structure contribute to noise reduction?
A: Yes. The sealed air pockets break up sound waves differently than open-channel ribs, which accounts for the higher acoustic attenuation compared to standard hollow sheets. This is relevant for both highway barrier and interior partition applications.
Q4: Is the product more expensive than standard hollow sheets?
A: There is a cost premium due to the more complex extrusion process. Whether that premium is justified depends on the project's structural, acoustic, or thermal requirements. For projects where multi-directional load resistance or acoustic performance is a primary criterion, the panel offers a more direct fit than hollow-sheet alternatives.
Q5: Will the hexagonal pattern look dirty or faded over time?
A: The hexagonal pattern is the internal structure of the panel, not a printed or applied design. Light scattered by the cell walls also makes minor surface dust and small scratches less visually prominent than on clear flat-panel formats.
Q6: How do you prevent internal condensation after installation?
A: Professional installation uses anti-dust breathable tape on the top and bottom profiles. This allows moisture vapor to escape while keeping dust and debris out of the internal channels.
