*Compatibility depends on the specific roof profile and clamp design.
Final dimensions, hardware, and installation requirements are confirmed according to the selected configuration and approved drawing.
Standing Seam Clamp Range
Standing seam clamps are selected according to the geometry and construction of the roof seam.
Our product range can be configured for different seam types and mounting requirements, including:
- Snap-Lock Seam
- Single-Fold Seam
- Double-Fold Seam
- Bulb / Round Seam
- Concealed-Fix Profiles
- Profile-Specific Seam Designs
Different clamp geometries are available for different seam dimensions and load requirements. Specific compatibility should be confirmed against the actual roof profile.
| Clamp Only | For customers with an existing rail adapter or mounting interface. |
| Clamp + L Foot | For conventional rail-mounted PV systems. |
| Clamp + Bolt Interface | For direct connection to compatible mounting rails or components. |
| Clamp + Rail Adapter | For integration with specified rail profiles. |
| Rail-Less Attachment | For mounting systems designed without conventional rails. |
| Profile-Specific Clamp | For roof profiles that require a dedicated clamp geometry. |
Clamp Configurations
If you already have a mounting rail, send us the rail profile so we can match the attachment interface.
Technical Resources
OEM / ODM Customization
A standing seam roof does not need to match an existing standard clamp. If your roof profile, mounting rail, or installation method is different, we can develop the attachment around your requirements.

Frequently Asked Questions
Do you have one universal standing seam clamp?
We provide several clamp configurations rather than relying on a single geometry for every seam profile. The appropriate clamp depends on the roof seam and mounting requirements.
What standing seam profiles can your clamps be used with?
The range can cover common snap-lock, single-fold, double-fold, bulb-shaped and other standing seam configurations. Exact compatibility should be confirmed from the roof profile.
Does the clamp penetrate the roof?
The standing seam clamp configurations are designed as non-penetrating attachments. They mechanically engage the seam rather than drilling through the roof panel.
How do I check whether a clamp fits our roof?
Send the seam profile drawing or a clear roof photograph with key dimensions. Roof manufacturer and panel information are also useful for confirmation.
Can you develop a clamp for a profile you do not currently have?
Yes. Profile-specific clamps can be developed from drawings, dimensions, photographs, samples, or other reference information.
Can the clamp connect to our existing rail?
Yes. L Foot, bolt-based, rail-adapter and other interfaces can be considered according to the rail design.
Can you supply rail-less configurations?
Yes. Selected clamp designs can be developed for direct module mounting or other rail-less mounting systems.
What materials are available?
Typical options include AL6005-T5 aluminum and stainless steel. Material and hardware can be specified according to the roof material, environment, and project requirements.
Can you manufacture according to our existing sample?
Yes. An existing clamp can be used as a reference for OEM/ODM development, subject to engineering review.
Need a Standard or Custom Clamp?
Send us your module details, rail profile, drawing, existing component, or specification.
