Vulcraft Composite Floor Decks are embossed with a design that binds with placed concrete, creating a single, strong unit. Our composite decks, along with the placed concrete, add value and efficiency to building projects, along with tremendous design flexibility. A variety of profiles and panel sizes, versatile side-lap connection options, outstanding acoustical properties, and multiple finishes will provide a floor system that adds value to your project.
Understanding Deck Designations
Whether it is a roof deck or a floor deck, the labeling of the deck is done in similar ways. Below is an example of what the parts of a designation mean.
Designations Vocabulary
- VI - Standard composite deck with nested side-lap
- VLI - Composite deck with interlocking side-lap
- VLR - Composite deck reversed
- PLVLI - PunchLok II side-lap connection
- D - Dovetail-Deck with nested side-lap connection
COMPOSITE DECK PROFILES
1.5VL & 1.5VLR COMPOSITE DECK PROFILES
1.5VL Composite Floor Deck features a profile that is 1.5 inches deep and is provided in 36’ panels with multiple finish options. It is available in with three side-lap connection options.
1.5 VLR is the inverse of 1.5VL. This profile, available in 36’ panels with multiple finish options, provides the wider parts of the ribs toward the bottom of the deck, which allows a greater amount of concrete to be included in the final deck-slab.

NEXT GENERATION DOVETAIL FORMLOK® DECK PROFILES
Our next-generation FormLok® Dovetail Deck profiles offer exceptional strength, load-carrying capacity, and design flexibility for demanding floor systems. Utilizing the unique geometry of the dovetail shape, this composite deck integrates seamlessly with concrete to create a durable floor system capable of handling heavy traffic and loads while achieving long spans with shallower floor depths. Available in a new 30” wide 2.0” profile and a 24” wide 3.5” profile, our re-engineered Dovetail Deck features excellent acoustical properties, fire resistance, and versatile finish options to suit various architectural needs. Enhanced by innovative hanging solutions like PinTail™ Anchors, these decks can support heavier loads or brace mechanical systems efficiently. With reduced material costs and construction time, FormLok® Dovetail Decks deliver top-tier performance for multi-story buildings and other high-demand applications.

COMPOSITE CELLULAR DECK PROFILES
In exposed ceiling areas that require a flat bottom design, Vulcraft’s Cellular Decking can give your project that look you need without compromising load capabilities. This versatile product is available in 1.5”, 2”, or 3” depths, and comes in 36” panels. Cellular deck acts as both a ceiling and a roof, combining the strength of roll formed steel with an aesthetically pleasing bottom plate. It provides even more value when you choose the available acoustical option.

SIDE-LAP CONNECTIONS
Please see data sheets for available side-laps for each profile.
Interlocking Side-lap
Interlocking Side-lap connections have a male side underneath that is high enough to reach the top of the female side above, and are attached with either a top seam weld or PunchLok II.
Interlocking Side-laps for Screw Connections
Interlocking Side-laps for Screw Connections attach using a screw installed at the low point where the male and female sides meet, with the bottom piece overlapping underneath.
Interlocking Side-lap for Punchlok II
Vulcraft’s exclusive PunchLok II System makes use of a specially designed pneumatic tool that requires no welding, installs up to 10 times faster than top seam welds, requires no touchup from top or bottom of the deck, and can be visually inspected without special tools or gauges.
Nested Side-lap
Nested Connections have overlapping pieces that nest into each other, allowing the deck to shift left and right for the perfect fit before final screw or weld connections are made.
Vulcraft Roof Decks are designed in accordance with the ANSI/Steel Deck Institute RD-2017. Vulcraft’s standard, acoustical and non-acoustical decks are IAPMO UES ER-652 UL and/or FM listed. Vulcraft’s Dovetail Roof Deck, acoustical and non-acoustical, are IAPMO UES ER-423, UL and/or FM listed. See datasheets for specific listings.
