The mechanical embossments on the surface of the deck are proprietary to Verco Decking, Inc. The standard profile contains 3 ribs and is 36 inches wide with opposing male and female edges, creating an interlocking side lap when installed. Type W3 FORMLOK™ profiles are 3-inch deep composite deck designed for longer span floor deck conditions. The difference between the PLW3™ FORMLOK™ profile and W3 FORMLOK™ profile is the method of sidelap attachment the panels themselves are identical in both geometry and material properties. The prefix “PL” designates a PunchLok® version of the W3 profile, while W3 alone indicates the top seam weld or button punchversion of the same W3 profile. The current industry use of mechanical fasteners ( Hilti and Pneutek), restraining elements ( ShearTranz® Systems) and the innovative PunchLok® IIside lap attachment system are all direct results of testing. Type B profiles are typically used for span conditions of 10 feet or less.Įxtensive full scale diaphragm testing is an ongoing effort with B deck to produce a more efficient roof diaphragm in terms of capacity and installation. The wide ribs make the profile an ideal structural substrate to uniformly support roofing systems applied on top of the deck. The profile contains 6 ribs and is 36 inches wide with male and female edges, creating an interlocking side lap when installed. Type B profiles are 1.5-inch deep structural roof deck that provide both vertical load and diaphragm shear capacity. The prefix “PL” designates a PunchLok ® II version of the B profile, while “HS” (high shear) indicates a top seam weld, button punch, or screw version of the same profile. The difference between the PLB™-36 profile and HSB®-36 profile is the method of sidelap attachment the panels themselves are identical in both geometry and material properties.
