Self pierce riveting for steel frame construction

Self pierce riveting for steel frame construction Henrob claims its self-piercing riveting systemhas several benefits over existing methods of joining zinc- coated steel are as follows. First off, self-pierce riveting is a cold forming process, so there is no burning of the zinc coating on galvanised steel sheet. This means that the corrosion resistance of the frame is not compromised and there is no need to dress and paint a weld zone. Also, the strength of the steel is not reduced, as may be the case in the heat-affected areas of a welded frame. Furthermore, no zinc fumes are given off during riveting, resulting in a clean working environment without the need for extraction. No holes are required for self-piercing rivets, so there is no swarf generated and there are no subsequent alignment problems. And no holes also mean no purchasing stocks of replacement drill bits; Henrob says the consumables needed for its riveting tools last in excess of 25,000 cycles. Henrob self-piercing riveting is a fast (around 2 seconds to set a rivet) one shot process giving a consistent, high quality joint. Henrob uses 5mm rivets for steel frame construction, and rivet length selection depends on material gauges and grades and joint strength requirements.
