Ariel Coroline Corrugated Sheet Fixings - Black - Pack of 20

These fixings are specifically engineered for use with Onduline Bitumen Sheets.

Each fixing is 60mm in length.

Each pack contains 20 fixings.

They are ideal for outdoor roofing applications, particularly with Onduline Bitumen Sheets. Always ensure the 60mm length is appropriate for your specific roof structure.

The colour-coded waterproof cap creates a reliable seal, preventing water ingress and maintaining roof integrity.

Yes, they are designed for both professional roofing contractors and DIY projects, offering quick and efficient installation.

Galvanised construction means the fixings have a protective zinc coating, providing exceptional resilience against weathering and corrosion.

Ensure the underlying support structure (purlin/batten) is sound and of sufficient depth for the 60mm fixing. Re-drive the fixing, ensuring it is straight and has engaged properly with the support.

Check if the waterproof cap is properly seated and intact. If damaged, the fixing may need to be replaced. Ensure fixings are installed in the crests of the corrugations, not the valleys, and are not over-tightened.

Verify you are driving through the crest of the corrugation into a solid support. Ensure the tool being used is appropriate and in good working order. If the support is too hard, consider pre-drilling a pilot hole if recommended for your specific support material.

While galvanized steel offers good resistance, prolonged extreme exposure can eventually lead to surface rust. If significant corrosion is observed, especially if compromising the fixing's integrity or the waterproof seal, consider replacement.
