Get unmatched diaphragm shear strength out of your roof structure with Verco's PunchLok® II System. Our sidelap system uses a specially designed pneumatic tool to create a high-quality interference connection by cutting and shearing interference in the interlocking sidelaps of our steel deck profiles, enabling you to generate higher shear strength or reduce the connection or steel deck weight. It is particularly beneficial for applications requiring high lateral resistance, adding significant value to your project.
Experience faster installation with the PunchLok® II System, saving you time and money.
The PunchLok® II System's secure fastening minimizes the risk of deck movement or failure, ultimately increasing safety. For use with Verco's 1.5", 2", and 3" interlocking deck types, the PunchLok® II tool is fast, effective, and provides excellent lateral diaphragm strength.
While specifying screwed sidelaps is common in low-seismic, wind-governed regions, Verco’s PunchLok® II System is designed to deliver enhanced diaphragm shear performance, meeting the demands of high-seismic areas. Designers can utilize our Bare Deck Diaphragm tool to quickly calculate bare deck diaphragm shear and stiffness for specific designs. This tool generates a project-specific datasheet for diaphragm capacity, providing more flexibility than historical paper catalogs to tailor your design.
