Bjarnes System banded clips
Banded sliding clips for 25 mm standing seam roofing on wood
What our banded sliding clips are designed for
Our banded sliding clips are designed for 25 mm standing seam roofing where you want a faster, more repeatable installation flow on wood substrates. They belong in projects where the roof build-up, seam type and clip installation method all need to work together without unnecessary delays on site.
This page focuses on the Bjarnes System banded clip variants that belong to this exact family: standard banded sliding clips for 25 mm seams and the banded stainless option for 25 mm seams with 7 mm structural mat. It stays tight on purpose, so buyers can quickly understand what fits this application and what should instead be chosen from another clip page.
In our banded sliding clip range
Hot-dip galvanised banded sliding clips
Choose our hot-dip galvanised banded sliding clips when you need a fast clip installation method for 25 mm standing seam roofing on wood and galvanised material is the right fit for the project environment. This is the straightforward choice for standard seam build-ups where you want the speed and consistency of a banded clip workflow without stepping into another clip family.
See technical details for our galvanised banded sliding clips on page 28 in the handbook
Stainless banded sliding clips
Use our stainless banded sliding clips when the roof still uses a standard 25 mm seam on wood but the material choice needs to move from galvanised to stainless. They give you the same banded installation logic as the galvanised version, while supporting projects where corrosion conditions, surrounding materials or specification requirements point you toward stainless clips.

Banded sliding clips for 25 mm seams with 7 mm structural mat
Choose our banded stainless sliding clips for 25 mm seams with 7 mm structural mat when the build-up includes that separation layer and the clip must match it correctly. This is the right option when a standard direct-to-wood banded clip would be the wrong fit, but you still want a banded installation method rather than moving into a different seam or roof system.
Detailed banded clip data in our handbook
Below you can compare the banded sliding clip variants that belong to this page: the standard 25 mm seam versions and the stainless banded option for 25 mm seams with 7 mm structural mat. The handbook is where you confirm the exact clip designation, included screw, material and the stated breaking and characteristic values.
If you are deciding between standard banded clips and other Bjarnes clip systems, the nearby handbook pages also help you verify how sliding clips fit into the wider roof movement logic and which wood fastening screws sit behind the installation detail.
Need help choosing the right banded clips?
If you are comparing galvanised vs stainless, working out whether the roof build-up needs the 7 mm structural mat variant, or checking how banded clips should sit alongside the rest of the clip layout, we can help. Our team can guide you toward the right Bjarnes System banded clip solution for the seam type, build-up and project conditions you are working with.
How do I choose between standard banded clips and the version for 7 mm structural mat?
Choose the standard banded clips when your 25 mm standing seam roof is fastened directly to wood without that added layer. Choose the 7 mm structural mat version when the build-up includes that mat and the clip needs to suit that assembly correctly. The key decision is the roof build-up itself, not just the seam width.
When is stainless the better choice than galvanised banded clips?
Stainless is the better choice when the project conditions, surrounding materials or corrosion demands make galvanised clips the wrong fit. Galvanised can still be the right option in the correct environment, but the material decision should always be made in the context of the full roof specification rather than clip price alone.
Are banded clips used in the fixed zone or in the moveable zone?
These products are banded sliding clips, so they belong where the roof needs movement to be allowed rather than locked. The fixed zone is handled with fixed clips, while sliding clips are used outside that zone so the sheet can move as the roof works through temperature changes and service conditions.
Are banded clips the right choice for welded seams?
No - this page is focused on banded sliding clips for 25 mm seams. If your project uses a welded seam, you should move to the welded-seam clip types rather than forcing a 25 mm seam banded clip into the wrong application.
Can banded clips on this page be used on concrete, sandwich panels or insulated roofs?
Not as the main scope of this page. The handbook places these banded sliding clips under fastening to wood. If your project moves into concrete, sandwich, sheet metal substrates or insulated roofs, you should instead choose from the relevant Bjarnes clip system for that build-up.
Can Unite help us choose the right banded clip solution for a project?
Yes. If you need help deciding between clip types, materials or roof build-ups, we can help you narrow the choice and make sure the clip family matches the application. That is especially valuable when the project includes different roof zones, movement requirements or a build-up that makes the wrong clip easy to specify by mistake.
