Get unmatched diaphragm shear strength out of your roof structure with Verco's PunchLok® II system. Our sidelap connection system uses a specially designed pneumatic tool to create a high-quality crimp in the interlocking sidelaps of our roof deck profiles, enabling you to use the same or lighter material. 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 while minimizing onsite downtime.

FEATURES

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 action.

ADVANTAGES

  • Dramatically increases the diaphragm shear strength of the deck versus using sidelap screws
  • Requires no touch-up from either the topside or bottom side of the deck
  • Can provide a completely weld-free system when used in conjunction with mechanical fasteners at supports
  • 100% effective from first attachment of install to last attachment
  • 100% accuracy of inspections of the attachment from the topside of deck

DESIGN TOOLS

Save time by utilizing our Bare Deck Diaphragm tool to quickly calculate bare deck diaphragm shear and stiffness for your specific configuration. With inputs that include deck type, support connection, sidelap connection (including PunchLok® II), and wind uplift, this tool will help you accurately determine diaphragm capacity without the need for paper tables.
