Dovetail Deck

Design Versatility.

At Vulcraft, we understand the desire to create something special for your client. The structure is a result of your vision, and we have developed a number of roof and floor solutions, including our Dovetail deck line, to help bring your vision to life. Vulcraft’s Dovetail Deck System uses the intrinsic strength and aesthetic appeal of the dovetail shape to provide the architectural and structural design communities with a variety of floor and roof deck design solutions.

Fit more into a multi-story building.

The Vulcraft FormLok Dovetail Composite Floor Deck is one of our most versatile and practical products. You can achieve long spans with shallower floor depths that enable you to fit more into multi-story buildings. Strength, fire resistance and acoustical performance: all are available with as little as 5 ½ inches of deck depth. Delivering design flexibility, dovetail just gives you the opportunity to create something truly impactful.


Vulcraft recommends Wedge Nuts to hang heavier loads or to brace mechanical systems. These fit easily in the deep rib and can easily be reconfigured to fit your design needs.


Superior Sound Ratings.

When used with a typical assembly, our dovetail deck acoustics give you design freedom like never before and provides superior sound performance – boasting a variety of floor assemblies and finishes that provide sound transmission ratings (STC) and sound impact ratings (IIC) over 50. Whether it’s engineered wood, ceramic tile or anything in between, our dovetail deck superior sound ratings give you the opportunity to create something that meets your customers’ needs and matches your creative vision.

Sound Transmission Class (STC) is a rating of how well a building partition attenuates airborne sound. It is widely used to rate interior partitions, ceilings/floors, doors, windows and exterior wall configurations.

Impact Insulation Class (IIC) is a rating of how well a building floor attenuates impact sounds, such as footsteps.


Along with its aesthetic design, dovetail acoustic roof deck uses proven sound-reducing technology to help lower levels of ambient background noise. Its excellent acoustical performance with a Noise Reduction Coefficient (NRC) of 0.95 to 1.15 can achieve greater clarity of original sound and deliver a calm, quieter interior environment especially in structures such as auditoriums, natatoriums, schools, gymnasiums, and theaters.

Sammy X-Press® Swivel Head Fasteners

Vulcraft recommends using Sammy X-Press® Swivel Head Fasteners to securely hang or brace your mechanical systems for dovetail or acoustic dovetail roof deck. These swivel head fasteners are easy-to-use and save you time and money on installation.

The Freedom to Use a Variety of Flooring Finishes.

Vulcraft’s FormLok Dovetail Composite Floor Deck helps give you the freedom to finish your floor any way you see fit. Thanks to its superior sound ratings, you can easily find a finish that meets code and fits your vision. Get a modern industrial look with exposed concrete. Choose engineered wood flooring for a more classic feel, or choose from a multitude of other materials to create something totally unique.
