product to use to protect galvanised sheets

Hi Jay,

Thank you for contacting Hilti.

Unfortunately, Hilti doesn't have products to protect galvanized sheets, such as zinc coatings.

That being said, after looking at the photos you have posted, I believe you might be talking about a facade edge of slab application. In these situations, we passive fire protection solutions, such as the firestop spray CFS-SP SIL.

If this is what you're looking for, the CFS-SP SIL is a silicone-based sealant spray used in conjunction with backfilling material to protect the gap/joint between the building structure and the facade and therefore avoid the spread of fire and smoke between floors.

For more information and technical support about the firestop solution mentioned above, please reach out to our technical support team >> Technical Advice Services - Hilti Australia

I hope the above is helpful.

Kind regards,
