The DeltaGrip® System
ASC Steel Deck’s revolutionary DeltaGrip® tool, a mechanical side-seam attachment system, reduces the installed costs of high shear diaphragms by eliminating the costly top seam weld. This clinching system punches three triangular tabs though the standing seam interlock side seam. The results of this interlocking system are as permanent and durable as a seam weld. As part of the ASC DeltaGrip system, the DeltaGrip tool resists longitudinal movement and vertical separation when subjected to wind, seismic or construction loads.
