Aluminum edge trim for polycarbonate is precisely extruded from 6063-T5 aluminium alloy. This profile is meant to cap, seal and protect the exposed perimeters of multiwall and solid polycarbonate sheets. This product is manufactured by Baoding Sinhai Sunboard Manufacturing Co., Ltd., a direct manufacturer with 30+ years of experience in the polycarbonate industry and 25+ production lines across 3 manufacturing facilities, designed to address thermal expansion movement, moisture ingress into sheet flutes and the risk of sheet blow-out during high-wind events. Standard length 6 m, for sheet thicknesses from 4 mm to 20 mm.
This profile is a decorative finish and a practical structural component in glazing and roofing systems. It seals the perimeter of the PC panels so that moisture and debris cannot penetrate the multiwall flutes—a major source of internal algae development and clouding over time. It also offers a mechanical anchor to keep the sheet steady when pressure fluctuates.
6063-T5 aluminium, as opposed to plastic alternatives, offers dimensional stability, corrosion resistance and long-term surface integrity and that is why it has become the standard specification for commercial and industrial applications.
Three main profile types are available to suit different installation requirements:
| Profile Type | Function | Typical Use |
|---|---|---|
| U-Edge Profile | Seals and finishes panel ends | Eave edges, cut ends, perimeter finishing |
| H-Connector Profile | Two-piece base + cap for joining panels | Joining adjacent sheets on roofing runs |
| F-Profile | Corner and wall-side finishing | Wall abutments, fascia connections |

Batch to batch consistency in composition of alloys. 6063-T5 temper has a tensile strength of ≥160 MPa and a yield strength of ≥110 MPa. Spectrometry analysis on each manufacturing run to verify alloy composition.Structural consistency,whether you order once or repeat order.
Allow for thermal expansion. PC sheets expand and compress with temperature. Each profile channel is sized to enable the sheet to slip inside the groove during thermal movement, thereby decreasing stress on the sheet edge and avoiding the popping noises associated with too hard fixes.
Resilient surface coverings. The anodised finish is 10-15 microns. The powder coated option is 60-80 microns. Both are available in silver anodised or bespoke powder coat colours to meet project demands.
EPDM gasket compatible The interior channel shape is designed to take EPDM or TPE gaskets to provide a compression seal to allow panel movement while preserving edge weathertightness.
Width range includes most sizes of PC sheets. The 4–20 mm compatibility means this trim range works across hollow multiwall sheets, solid PC sheets and corrugated PC panels, therefore minimising the amount of various accessories needed on a single project.
Each profile is dimensionally verified prior to shipping. The channel width is tested against the tolerance of the sheet thickness to prevent gaps in installation, rattling or routes for water intrusion.
Cross-hatch tape tests are used to assess the adherence of coatings and to ensure that the finish will resist mechanical stress. The salt spray test is used to assess corrosion resistance notably for export orders meant for coastal areas or high humidity areas.
Gasket seat shape is validated to ensure that EPDM and TPE gaskets compress properly in the channel to maintain a uniform weatherseal at the panel perimeter.
Aluminum edge trim for polycarbonate is utilised in several building and infrastructure applications:
Industrial skylights and warehouse roofs – U-profiles retain multiwall sheets at the perimeter, sealing the roof edge under varying pressure and wind loads.
Greenhouses and agricultural buildings – The aluminium edge seal is resistant to high humidity and chemical exposure and seals sheet cavities against pest invasion.
Highway infrastructure and acoustic barriers — The trim is combined with strong polycarbonate sound walls to give the edge grip required to endure continuous vibration and lateral wind pressure.
Canopies, Pergolas, Commercial Glazing F-profiles and H-connectors provide a smooth finish at wall abutments and panel joins.
OEM lengths and colours supported. Factory cutting is available on request for projects that need 3 m pieces instead of the typical 6 m.
Custom powder coat colours are suited to project requirements. Free samples prior to bulk purchases to confirm fit with your PC sheet thickness.
3 manufacturing locations and 25+ production lines, processing large-volume & mixed-container orders without interruption. Regular orders are generally processed in around one week. Warehouse resources in Tashkent and Dushanbe enable regional distribution in the Central Asian markets.
Aluminum edge trim for polycarbonate profiles are packed and shrink-wrapped to avoid any surface scratches during shipping. Sea, truck and air transport options available, logistical services include customs clearance and cross border paperwork.
Q1: My polycarbonate sheets are making loud popping noises in the afternoon. What is causing this?
A: This is thermal expansion noise. PC sheets expand as temperatures rise. If screw holes are undersized or the H-profile channel is too tight, the sheet edge cannot move freely and snaps against the fixing. Pre-drill holes 2 mm larger than the screw shank diameter and use H-profiles with adequate channel depth to allow for expansion.
Q2: Do you hold stock of this product?
A: Yes. Aluminum edge trim is a regular stocked accessory. Inventory is maintained for prompt dispatch on standard sizes.
Q3: Can you cut profiles to 3 m instead of the standard 6 m?
A: Yes. Standard stock is 6 m. Cutting to 3 m or other lengths is available as a factory service — specify your required length when ordering.
Q4: Can you deliver directly to my freight forwarder's warehouse?
A: Yes. Delivery to a nominated forwarder warehouse is fully supported regardless of location.
Q5: How long will the trim last in outdoor conditions?
A: With proper installation, the service life is 10+ years. The 6063-T5 alloy and the anodized or powder-coated surface provide resistance to UV exposure and weathering over the long term.
Q6: Is the trim compatible with structural silicone sealants?
A: Yes. Anodized product is chemically compatible with neutral-cure structural silicones. A primer is recommended for maximum adhesion in high-load applications.
