Verco Decking
Steel decking is used in many applications, but is particularly well suited to roofing and flooring. For more than 50 years, Verco has been manufacturing many different types of deck, including roof deck, floor deck, composite floor deck, cellular and dovetail deck. Following are the details you’ll need about any of our products. You’ll get the answers that will help make your next project a success.

Diaphragm Shear TablesUniform Load Tables
Acoustic Deck OptionsThe 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 weld, button 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.

Acoustic Deck OptionsThe difference between the PLN3™ profile and HSN3 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 N profile, while HSN indicates a top seam weld or button punch version of the same profile.
Type N profiles are 3-inch deep structural roof deck that provide both vertical load and diaphragm shear capacity. The profile contains 4 ribs and is 32 inches wide with male and female edges, creating an interlocking side lap when installed. The 3-inch deep ribs make N deck ideal for longer span conditions where B deck falls short. N deck is typically used for span conditions greater than 10 feet or when a specific aesthetic look is desired. The narrow low flutes and wide high flutes of N Deck create a very uniform look from the bottom side.

Acoustic Deck OptionsThe difference between the PLN™ FORMLOK™ profile and N 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 N profile, while N alone indicates the top seam weld or button punch version of the same N profile.
Type N FORMLOK™ profiles are 3-inch deep composite decks. The standard profile contains 3 ribs and is 24 inches wide with male and female edges, creating an interlocking sidelap when installed. The mechanical embossments on the surface of the deck are proprietary to Verco Decking, Inc. and were strategically designed to increase the shear bond strength between the concrete and steel. N FORMLOK™ deck can be used as a composite deck or simply as a form deck.
All FORMLOK™ products are considered composite assemblies (steel deck and concrete act compositely). If the FORMLOK™ designation is not present, the product is a form deck, not a composite deck.

The prefix “PL” designates a PunchLok® version of the W3 profile, while W3 alone indicates the top seam weld or button punch version of the same W3 profile.
Type W3 FORMLOK™ profiles are 3-inch deep composite deck designed for longer span floor deck conditions. The standard profile contains 3 ribs and is 36 inches wide with opposing male and female edges, creating an interlocking side lap when installed. The mechanical embossments on the surface of the deck are proprietary to Verco Decking, Inc. and were strategically designed to increase the shear bond strength between the concrete and steel. W3 FORMLOK™ deck can be used as a composite deck or simply as a form deck.

The prefix “PL” designates a PunchLok® version of the W2 profile, while W2 alone indicates the top seam weld or button punch version of the same W2 profile.
Type W2 FORMLOK™ profiles are 2-inch deep composite deck designed for shorter span floor deck conditions. The standard profile contains 3 ribs and is 36 inches wide with opposing male and female edges, creating an interlocking side lap when installed. The mechanical embossments on the surface of the deck are proprietary to Verco Decking, Inc. and were strategically designed to increase the shear bond strength between the concrete and steel.

Diaphragm Shear TablesUnshored Span TablesShallow VERCOR™ is a 9/16 inch deep deck that is manufactured from G90 galvanized steel with a yield strength of 80 ksi and is available in 22-26 gage. Galvanized VERCOR deck can be considered permanent form. Uncoated decks should not be considered permanent forms; therefore, the weight of the slab on uncoated decks should be deducted from the allowable load of the reinforced slab. Uncoated deck is available only as a special order.
Welding VERCOR™ decks lighter than 22 gage requires weld washers in accordance with AWS D1.3.
