4mm-20mm H profile for Polycarbonate sheets connecting

How to use Polycarbonate H profile to connect the polycarbonate sheets

H profile for polycarbonate sheet connecting thickness 4mm; 6mm; 8mm; 10mm; 12mm; 14mm; 16mm; 18mm; 20mm.

Using a polycarbonate H-profile to connect polycarbonate sheets is a straightforward process and is commonly employed in various applications such as roofing, glazing, and DIY projects. Here’s a step-by-step guide on how to use a polycarbonate H-profile to connect two polycarbonate sheets:

Tools and Materials You Will Need:

Polycarbonate H-profile
Two polycarbonate sheets
Measuring tape
Saw (if you need to cut the H-profile or sheets to size)
Screws or fasteners (typically self-tapping screws)
Screwdriver or power drill
Silicone sealant (for additional waterproofing, if desired)

Step-by-Step Guide:

Measure and Cut:

Measure the length of the polycarbonate sheets and the distance between the support structures (such as rafters for a roof).
If necessary, cut the H-profile and the polycarbonate sheets to the required length using a saw.
Prepare the Sheets:

Ensure that the edges of the polycarbonate sheets are clean and free of any dust or debris.
Position the H-Profile:

Place the polycarbonate H-profile on top of the first sheet, positioning it along the edge that will be joined with the second sheet.
Attach the First Sheet:

Secure the H-profile to the first polycarbonate sheet by using screws or fasteners. Make sure to place the screws evenly and at the recommended spacing provided by the manufacturer.
Position the Second Sheet:

Place the second polycarbonate sheet on top of the H-profile, aligning it with the first sheet.
Secure the Second Sheet:

Using screws or fasteners, attach the H-profile to the second sheet. Again, ensure that the screws are evenly spaced.
Check Alignment:

Verify that the two sheets are properly aligned, and the H-profile securely holds them together.
Additional Waterproofing (Optional):

To create a watertight seal and prevent water infiltration, you can apply a bead of silicone sealant along the top of the H-profile before attaching the second sheet. This can help ensure a waterproof connection.
Trim Excess: If there is any excess H-profile extending beyond the sheets, trim it to match the sheet’s edges for a clean finish.

Repeat as Needed:

If you have additional sheets to connect, repeat the process, ensuring that each sheet is properly aligned and secured with the H-profile.
Using a polycarbonate H-profile provides a secure and watertight connection between polycarbonate sheets, making it an effective method for a range of applications. Following our recommendations and guidelines for the specific H-profile you’re using is essential to ensure a successful installation.



A polycarbonate H-profile, often referred to as an H-bar or H-connector, is a component used in various applications involving polycarbonate sheets. Polycarbonate is a transparent, durable, and lightweight thermoplastic material known for its impact resistance and excellent light transmission properties. H-profiles are designed to connect two polycarbonate sheets, creating a secure and watertight seal while maintaining the structural integrity of the sheets. Here are some of the key features and functions of a polycarbonate H-profile:

Sheet Connection: The primary function of a polycarbonate H-profile is to connect two adjacent polycarbonate sheets. These sheets may be used in applications such as roofing, glazing, or signage. The H-profile fits snugly over the edges of the polycarbonate sheets, holding them together securely.

Watertight Seal: H-profiles are often used in applications where it is essential to prevent water infiltration, such as in greenhouse roofing or skylights. The design of the H-profile helps create a watertight seal between the two polycarbonate sheets, preventing leaks and maintaining a dry and controlled environment.

Structural Support: Polycarbonate sheets are lightweight and flexible, making them vulnerable to bending or sagging over time. H-profiles add structural support to the connection between the sheets, helping to distribute the weight evenly and maintain the integrity of the installation.

UV Protection: Many polycarbonate sheets are used outdoors and are exposed to sunlight. Polycarbonate H-profiles may include UV inhibitors that help protect the polycarbonate sheets from the harmful effects of ultraviolet (UV) radiation, which can cause yellowing or degradation over time.

Ease of Installation: H-profiles are designed for ease of installation. They typically feature a straightforward design that allows for a quick and secure connection between the polycarbonate sheets, reducing installation time and labor costs.

Versatility: H-profiles are available in various sizes and configurations to accommodate different thicknesses and dimensions of polycarbonate sheets. This versatility makes them suitable for a wide range of applications, from small-scale DIY projects to large commercial installations.

Aesthetic Considerations: Some H-profiles come in various colors and finishes to match the overall design and aesthetics of the application, providing a polished and finished look.

In summary, a polycarbonate H-profile is a practical and functional component for connecting and securing polycarbonate sheets in various applications. It offers watertight sealing, structural support, UV protection, and ease of installation while maintaining the transparency and durability of the polycarbonate material.
