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.  The prefix “PL” designates a PunchLok ® II version of the B profile, while “HS” (high shear) indicates a top seam weldbutton punch, or screw version of the same profile.

Type B profiles are 1.5-inch deep structural roof deck that provide both vertical load and diaphragm shear capacity.  The profile contains 6 ribs and is 36 inches wide with male and female edges, creating an interlocking side lap when installed.  The wide ribs make the profile an ideal structural substrate to uniformly support roofing systems applied on top of the deck.  Type B profiles are typically used for span conditions of 10 feet or less.

Extensive 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 current industry use of mechanical fasteners (Hilti and Pneutek), restraining elements (ShearTranz® Systems) and the innovative PunchLok® II side lap attachment system are all direct results of testing.
