Fixing the medium channel to the sign blanks can be achieved using a traditional mechanical fixing such as blind rivets or pop rivets, But the channel can also be bonded to the sign blank using a structural bonding tape such as Stykra 700.  

What clips work with sign channel?

All of our anti-rotational sign clips (post clips) and channel clamps are compatible with all of the sign channel variations we stock. Thanks to the design of the various sign channel variations, all of the sign clips, channel clamps and screw banding can be used interchangeably with all the channel types.

What sign channel variations are available?

We stock small, medium, medium interlocking and large sign channel. The correct sign channel to choose is dictated by the size of the sign blank and also if the blanks are being joined together to create a larger sign.

Small Sign Channel - signs under 1m/sq

Medium Sign Channel - signs over 1m/sq

Medium Interlocking Sign Channel - signs being tiled / joined together

Large Sign Channel - large sign installations and motorway blanks  

As well as size and colour variation, we also offer our sign channel with structural bonding tape already applied. This can speed up your sign fabrication process and provide a fixing free sign face. Another advantage of structural bonding tape is that is does not require any special tooling or machinery in comparison to traditional rivets / flush rivets.
