Mezzanine Floor Systems for Your Steel Building
Mezzanines allow you to make use of overhead space within your building, adding extra square footage without incurring the cost of expanding the ground floor. Kirby offers some of the most efficient mezzanine options available in the steel building market – custom engineered to your specifications. Along with our standard mezzanines, Kirby offers the Ecospan® Composite Floor option. Our economical, innovative Ecospan system provides all steel and open web structural components for mezzanines and incorporates the benefit of open web configuration with maximum joist spacing.
Using a unique configuration of components with high strength-to-weight ratios, Ecospan allows for longer spans, shallow floor depths, greater rigidity, and enhanced performance. Made with 97% recycled steel joists and over 70% recycled steel decking, Ecospan mezzanines offer the benefits of sustainable building materials that may qualify for LEED® points through the US Green Building Council.
Easy and Fast Mezzanine Installation
Ecospan is easily installed using our exclusive, patented screw-down Shearflex® HD Connector, secured with a uniquely designed Shearset Tool included with each system. Each connector is placed in under 10 seconds – no wood, shoring or stripping required. Your mezzanine system can also be designed with no on-site welding. Once the floor system decking is in place, your mezzanine is ready for concrete.
The Economical Mezzanine Solution
Lightweight, shallow, composite joists mean greater rigidity, as well as a more economical solution, for your mezzanine. Ecospan’s joists range from 10” to 40” deep, with lengths up to 60’ feet. They are typically spaced at 4’ to 6’ on center, allowing installation flexibility for mechanical, electrical and plumbing systems for your building.
Superior Noise Control
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.
