Joint development by the Metal Dek Group® and Diversakore™

Long Spans. Low Profile. Fast Construction.

Versa-Floor™ integrates Metal Dek Group’s innovative floor system profiles – Deep-Dek® Composite and Versa-Dek® Composite 3.5LS – with VERSA:T: Beams and KOREFLEX columns. Results are low-profile floor assemblies with open- space feel and 2-hour UL unrestrained, unprotected fire assembly ratings. Optional coatings can brighten interior spaces and accommodate mild to severe environmental exposure.

Engineered Solutions

VERSA:T: Beam and KOREFLEX columns work integrally with the Deep-Dek® Composite or Versa-Dek® Composite 3.5LS deck assemblies to form a low profile system that provides for attractive open space design. Versa-Floor™ combines the speed of steel construction with the mass of concrete to create an Engineered Solution the meets stringent performance and structural requirements. It can also be tailored for any level of environmental exposure. Versatility, appearance, efficiency, speed of construction and, most importantly, durability are hallmarks of each solution.

With so much design flexibility, cost effective and efficient solutions can be engineered to address most markets. However some common applications include: Parking, Healthcare, Mixed-Use, High-Rise, Residential, Office, Transfer/Podium Slabs, High-Load Flooring, Laboratories, and more...

Steel competes admirably on projects with aggressive construction schedules. Efficient installation techniques employed by a reduced labor pool accelerates the process. Controlling labor and equipment costs is vital to assuring desirable profit margin.


  • Combine with structural steel frame to accommodate accelerated construction schedules
  • Just-in-time material deliveries
  • Time honored installation methods & techniques
  • Less prone to weather delays
  • Simplified beam & adjustable post shoring method
  • Ease of inspection


  • Reduced labor pool compared to traditional CIP concrete methods
  • Placed deck provides immediate, safe working platform

Cost Efficiency

  • Controlled labor & equipment costs
  • Combines “permanent” in-place formwork & in-service positive bending reinforcement of slab
  • Minimal shoring


  • Low-profile composite deck systems reduce…
    • Floor-to-floor & overall height of structure
    • Stair, elevator & M/E/P extensions
    • Curtainwall surface area
  • Dek-Strut™ or Versa-Wedge™ hanging devices for M/E/P services

Visual Appeal

Sustainable Construction

  • Optimize Energy Performance
    • Concrete = thermal mass = stabilized temperatures = reduced energy consumption
  • Construction Waste Management
    • Ability to divert unused product from Landfill
    • Small amount of job site waste and what little there is 100% recyclable
    • Unrelated: Steel used is fully recyclable at the end of the building’s life
  • Recycled Content
    • Steel has over 80% recycle content
  • Local/Regional Materials
    • Higher likelihood products manufactured regionally (within 500 miles of site)
  • Low-Emitting Materials: Paints and Coatings
    • Lower or eliminate release of on-site VOC’s with factory painted decking
