Aluminum H-Connector for PC Panel Joining
Baoding Sinhai Sunboard Manufacturing Co., Ltd. - Precision-extruded structural profile for aluminum h-connector that firmly connects two neighbouring polycarbonate panels. It is made from Aluminium 6063-T5, can accommodate panel thickness from 4 mm to 20 mm and is available in standard 6 meters length with optional custom cuts. Available in anodised silver, black and bronze finishes. Produced on over 25 lines with an annual production of over 60,000 tonnes and over 30 years of manufacturing expertise.
What Is an Aluminum H-Connector?
A structural connecting profile built of 6000-series aluminium alloy is called an aluminum h-connector. It joins two neighbouring panels – polycarbonate, ACP or glass – in roofing, facade and partition systems.
This profile enables micro-movements due to temperature changes without losing its waterproof and airtight characteristics, unlike hard joining techniques. It reduces panel buckling and keeps moisture from entering the structure—two of the primary causes of long-term damage to curtain wall and roofing systems.
The Base + Cap two-piece construction makes installation easy. First attach the base and then snap the cap over the sides of the panel for a neat finish.

Material & Surface Treatment
The profile is made of Aluminium 6063-T5 temper, tensile strength of ≥ 215 MPa and yield strength of ≥ 170 MPa. This alloy grade is often used in architectural extrusions for its clean machinability, good coating response and air corrosion resistance.
Surface treatments choices include anodising in silver, black or bronze with anodising thickness of 15-25 microns – for outdoor and moderately corrosive situations. Custom colour powder coating is also available.
Higher micron anodising with PVDF coating may provide an added level of resistance to chloride-induced pitting in coastal or high humidity conditions.
Product Advantages
High stiffness with inherent expansion tolerance. The H-channel has a special expansion space to allow for modest movement of the panels when the temperature changes. No more creaking and popping from a joint too tight and the sheet can't move easily under midday heat.
High facades with high resistance to wind. This profile is ideal for high-rise and large-span roofing applications where wind uplift is a problem given the 6063-T5 alloy and two piece locking system.
Non-combustible and UV stable. Aluminium is Class A1 non-combustible and does not yellow or deteriorate under UV exposure like PVC profiles. It is totally recyclable, thus it is in line with the sourcing of green construction material.
The aluminum h-connector ensures consistency between batches. The alloy composition is validated with a spectroscopic study to ASTM or EN standards, ensuring the least chance of stress-corrosion cracking over time.
Where It Is Used?
This profile is for a broad variety of commercial and industrial applications:
- Industrial skylights and roofs – fastens multi-wall polycarbonate sheets in logistics centers and warehouses, coping with snow loads and wind pressure
- Architectural facades – connects panels on commercial buildings with a flush finish, allowing for structural movement
- Cleanroom and modular partitions — for pharmaceutical and semiconductor companies that need crevice-free, chemically resistant junctions
- Greenhouses & canopy structures – Pairs with hollow PC sheets for daylighting applications
- Corridors, pergolas and covered pathways - Offers a clean edge-to-edge panel joint for outdoor buildings
Quality Control Process
Every batch is subjected to a multi-step inspection procedure:
- Dimensional precision is tested using digital projectors to ensure tolerances within ±0.1 mm – necessary for a leak-proof fit
- Webster hardness testing demonstrates temper uniformity throughout the extrudate
- Tensile tests show load-bearing capability according to specifications
- Salt spray testing (ASTM B117) is used to mimic the effects of corrosion in a coastal environment.
- Cross-hatch adhesion testing (ASTM D3359) tests the durability of the coating under mechanical stress.
- Spectroscopic examination validates alloy composition from lot to lot
Xinhai’s quality management system is ISO 9001:2015 certified and products are evaluated for CE and RoHS compliance.
Customization & Supply Options
This profile is available in standard lengths of 6 m or trimmed to 3 m on request. Custom extrusions are available for non-standard panel thicknesses outside the 4-20 mm range. The surface treatments, colours and lengths may be tailored to suit the needs of the project.
We can help you as an OEM or ODM. Standard orders normally take around a week to fulfil.
Xinhai has local stock in Tashkent and Dushanbe, and can deliver to the warehouse of your goods forwarder. Logistics alternatives such as sea freight, truck and air transportation with custom clearance help.
FAQ
Q1: My sheets are popping and making loud noises in the afternoon. Why?
A: This is thermal expansion noise. PC sheets expand as they heat up. If the H-profile is too tight, the sheet pushes against the fasteners. Pre-drill holes 2 mm larger than the screw shank and use H-profiles with built-in expansion gaps to address this.
Q2: Do you have stock available?
A: Yes. This is a regularly stocked accessory with inventory available for prompt shipment.
Q3: Can you cut it to 3-meter lengths?
A: Standard stock comes in 6-meter lengths. A cutting service to prepare 3-meter pieces is available on request.
Q4: Can you ship to my freight forwarder's warehouse?
A: Yes, delivery directly to your nominated warehouse address is supported.
Q5: How long does it last outdoors?
A: With proper surface treatment and installation, this prodcut has a service life exceeding 10 years under normal outdoor conditions. Actual service life varies depending on environment, installation quality, and maintenance.
Q6: How do I ensure watertightness at the joint?
A: Use EPDM gaskets or high-modulus silicone sealants inside the H-channel. For critical applications, performance can be verified against ASTM E331 water penetration standards.
