Ecospan System

The Ecospan Composite Floor System provides innovative, results-driven building solutions that provide excellent value for safety, sound and fire ratings and design flexibility. Ideally suited for multistory residential and commercial buildings, the Ecospan Composite Floor System is an innovative, simple, effective and economical method of providing all steel, open web structural components for elevated floor construction. Ecospan incorporates the benefit of open web configuration along with 48” to 72” joist spacing. This allows for maximum design and installation flexibility of HVAC and Electrical systems.

Ecospan's Composit Floor System uses a unique confiruration of components.

Ecospan is easy to install. It is especially effective in industrial and commercial mezzanines, including in metal building and renovation projects where erection crews benefit from our self-drilling Shearflex HD fasteners (Link this to the Shearflex fastener page) and/or bolted attachments of all components. Ecospan can be designed to require no welding.

The Ecospan Composite Floor System is fabricated at Vulcraft/Verco plants throughout the United States, so freight costs are minimized with closer proximity to your next project.

Ecospan offers many clear advantages over conventional construction techniques including:

Vulcraft Steel Joists

High strength-to-weight ratio allows for greater spans and spacing with lighter members than traditional joists. Ranging from 10” to 30” deep and a maximum length of 50’, Ecospan joists are typically spaced at 4’ on center, allowing HVAC and electrical design and installation flexibility.

Vulcraft/Verco Steel Decking

Multi-span sheets of light gauge decking eliminate short sheets, reduce weight and improve safety.

Shearflex® HD Screw

With an average installation time of 10 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, 3/8” diameter screws in a uniform pattern using a Vulcraft-provided Shearset®Tool.

Slab Reinforcement

Provided by the General Contractor, the slab reinforcement typically consists of 6x6 welded steel wire or fiber mesh.

Concrete Slab
(by others)

Slab thickness is typically 2 1/2” (3 1/2” total depth) normal weight concrete having a minimum 28 day ultimate compressive strength of 3,000 psi.
