Ecospan is economical

Ecospan over-delivers on value while maintaining economy through ecology. No plywood forms or shoring saves time and costly handling. Sub-trades can begin work the day after concrete is poured.

The Benefits of Ecospan

Simple, fast installation means a minimal learning curve for contractors, saving time and money. No wood, shoring or stripping is required.


48” to 72” on center joists mean simpler design and layout, increasing efficiency and making the design and installation of mechanical, electrical, and plumbing systems easier.


Lightweight, shallow composite joists mean greater rigidity. Ecospan has been extensively tested for structural capacity by leading universities.


The Ecospan System uses an exclusive, patented, screw-down Shearflex HD Connector, which is installed with a uniquely designed manual tool included with each system.


The time required to install each Shearflex HD Connector is three to eight seconds, significantly less time than other techniques.


Once the floor system decking is installed, concrete is ready to be poured.


Compatible with any load bearing wall framing system including: structural steel, steel studs, light gauge CFS, masonry, concrete and insulated concrete forms. Composite design allows for longer span with less joist depth.


Provides a safe, stable working platform in a single step, which reduces construction liability. Non-combustible with several UL fire resistance ratings for 1, 2, and 3 hours.

Noise Reduction

Ecospan received a Sound Transmission Classification Rating of 57 in acoustical tests conducted by the renowned Riverbank Acoustic Laboratory. Impact Insulation Classification tests were also impressive with minimal sound attenuation materials required.


Joist and decking materials are standard and produced at Nucor Vulcraft/Verco plants throughout the U.S., which cuts freight costs and speeds materials to the job site.

Ecospan's Patented Innovation


The Science of Shearflex

With an average installation time of 3 - 8 seconds per screw, these patented self-drilling, self-tapping connectors are easy and inexpensive to use. Workers install the 2 1/2” or 3” long, 5/16” diameter screws in a uniform pattern using a Vulcraft-provided Shearset Tool. More »
