Gesipa BulbTite Rivets are the original load spreading rivets. Initially developed for the steel building industry, BulbTite have found to be excellent for many other applications including truck and trailer building, height safety and abseiling anchor point installation, ventilation systems and roofing.
Due to the design, the rivet body folds into three legs creating a large blind side surface area. As a result BulbTite is perfect for thin sheet metals. An EPDM rubber seal assists in creating a weather proof seal.
Two great tool options are the Powerbird PRO BT and the HN2 BT. Because these tools are engineered by Gesipa you get special nose tips and jaws to properly set bulbtite rivets.
In Australia the height safety industry has developed fall arrest systems which use the Gesipa RV6605-9-6W to secure harness points to thin roof sheet such as colorbond. First of all this is a quick, easy and secure way to install anchor points. Secondly the rubber seal and locked mandrel create a water tight joint which is required for this type of install.
I addition the RV6604-0604W has been a populat choice for the isnatllation of Lysaght roof sheet. Much like with anchor point installation this rivet provides strength, clamping and waterproofing in rood joint applications.
