Flame Resistant Mezzanine Decking System

Flame Resistant Structural Flooring System Solution
ResinDek® Xspan® FR

Like ResinDek Xspan, ResinDek Xspan FR (flame resistant) is a structural mezzanine decking floor solution that does not require metal corrugated substructures. Even better, ResinDek FR Xspan panels are even stronger than regular ResinDek Xspan. This means that a portion of the cost to provide the fire rating can be offset through proper engineering of the flooring system. ResinDek FR Xspan fire retardant mezzanine decking is tested and capable of supporting 275 psf dead loads at 32" center supports and 3,000 lb. pallet jack loads (refer to the website for load span tables). Structural supports must be reviewed and approved by Cornerstone Specialty Wood Products, LLC® and must be capable of supporting floor loads at specific intervals. For further details, call us and/or your local building code official. ResinDek Xspan FR meets ASTM E-84 Class "A" flame spread less than 25, meets UK Class "O", as well as European standards EN 13501-1 and is rated as CFL-s1.

ResinDek fire resistant flooring panels are manufactured in the United States at our Louisville, KY plant, which has been awarded ISO 9001 certification. Because of our expanding presence in Europe, our ResinDek panels have been independently audited by a recognized EU notified body and we have received factory process controls and obtained a CE mark for all ResinDek panels. With ResinDek panels, you can trust that the quality goes in before the name goes on.

The top of the decking panel is available with Gray Diamond Seal® 2, Gray Diamond Seal® 2 with ESD or TriGard® with ESD for superior cleanability, stain, scratch resistance and certified static control. The underside comes standard with a galvanized finish or white finish. With an unmatched ten-year warranty you can rest assured that your floor will be a showcase for years to come.

We manufacture ResinDek Xspan FR fire resistant panels with wood fibers that are specially sorted and processed, incorporating customized formaldehyde free resins, and a wax emulsifier. Under extremely high pressure and temperature, the materials are combined and compressed resulting in a panel with superior physical properties that are especially designed and built to withstand heavy rolling cart and pallet jack loads.

All ResinDek Xspan FR fire resistant panels are custom manufactured and available in sizes up to 4' x 10' with specially designed tongue and groove configurations. ResinDek tongue and groove configurations promote effective panel to panel wheel load transfers. When required, tongue and groove configurations are available on all 4 sides.

ResinDek MetaGard Surface
MetaGard® (Patent Pending)

ResinDek flooring panels with the MetaGard surface combines the structural integrity of the ResinDek panel along with the strength and durability of a steel wearing surface. The MetaGard steel surface is fused to the ResinDek panel with a proprietary bonding agent and features an edge that encapsulates the perimeter of the panel. This creates a floor that will not delaminate, has superior physical properties, is level for rolling loads, and has no sharp edges that could cut or snag objects passing over it.

  • Designed for heavy wear areas, and robotic applications (AGV and AMR), drop zones, or where heavy loads are dragged across the floor.
  • The MetaGard surface is available in galvanized and stainless steel. Other steel variations may be available to fit your particular application.
  • ResinDek with MetaGard has been tested per ASTM D2047 standards and has been found to meet or exceed OSHA specification for slip resistance.
  • The MetaGard finish has electrostatic dissipative properties which protect sensitive electronic equip-ment from damage.
  • Easier to install and less expensive than diamond plate, bar grate, and concrete
  • Provides a smooth transition between ResinDek and ResinDek with MetaGard
  • Improved noise abatement compared to diamond plate

ESD Finish
ESD - Electrostatic Dissipative Finish for Gray Diamond Seal® 2, TriGard® Coatings and MetaGard®

With our electrostatic dissipative finish, ResinDek® mezzanine floor panels with ESD provide an outstanding static control solution for electrically sensitive devices such as laptops, bar-code scanners, servo-drive motors, and pick-to-light systems that are common in distribution centers. Not only will the ESD finish eliminate expensive electronic devices downtime caused by electrostatic discharges, but it will also prevent uncomfortable static shocks to employees. ESD is standard with TriGard® and is available with Gray Diamond Seal® 2.

ResinDek® panels with ESD have been subjected to extensive independent testing, and have been found to be in compliance with the following ESD Association specifications:

  • ANSI/ESD S7.1 - Resistive Characterization of Materials–Floor Materials.
  • ANSI/ESD S20.20 - Protection of Electrical and Electronic Parts, Assemblies and Equipment.
  • ANSI/ESD STM97.1 - Floor Materials and Footwear–Resistance Measurement in Combination with a Person.
