... BULB-TITE blind rivets are folding type rivets made of aluminium, steel or monel/stainless steel. These special blind rivets have been specially designed for applications in the building sector, where fassade or roof elements must be fastened together or to steelbeam structures. The way the mandrel is secured in the rivet shaft provides moisture protection. Additionally, BULB-TITE rivets can be fitted with a special Neoprene sealing ring which still improves this characteristic.
Some BULB-TITE rivets have been awarded DIBt-Approval (German Technology Institute for Building Standards) and are therefore privileged fasteners among the building industry.
