Engineered Structural Flooring System Solution
ResinDek® Xspan®

ResinDek® Xspan® is a 1 1/8" thick panel that offers the look, maintainability and performance of ResinDek in a structural flooring system where a metal corrugated substructure is not required. The ResinDek Xspan structural floor system has been extensively tested and is capable of supporting 125 psf. dead loads at 32" center supports and 2,300 lb. pallet jack loads without corrugated metal B deck. Please refer to the table below for ResinDek for allowable point loads, uniform loads and pallet jack live and dead loads.

ResinDek Xspan resin flooring panels have been approved by IBC Code Officials for use as a structural flooring system in certain applications. 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 comes standard with an unfinished underside. High gloss white to enhance lighting, shown on this page, is also available. The top of the decking panel is available with Gray Diamond Seal® 2, Gray Diamond Seal® 2 With ESD or TriGard® with ESD.

The ResinDek Xspan engineered flooring panel is manufactured with specially sorted and processed wood fibers, customized formaldehyde free resins, and a wax emulsifier. The ingredients are combined and compressed under extremely high pressure and temperature, resulting in a panel with superior physical properties that are especially designed and built to withstand heavy rolling cart and pallet jack loads.

ResinDek Xspan structural floor is available in sizes up to 4' x 10' (1220 mm x 3048 mm) and custom manufactured to fit your needs. 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.

  • Superior wear resistance – tested in accordance with Taber Abrasion ASTM D4060.
  • Excellent slip resistance – tested in accordance with ASTM D2047, BS 7976-1-3:2002
  • Superior scratch resistance – tested in accordance with Hoffman Scratch Hardness Tester.
  • Standard with anti-static protection (also available with optional ESD, electrostatic dissipative, protection).
  • Can be easily cleaned using a damp mop or standard cleaning solvents without the fear of damaging the surface.
TriGard Finish
TriGard® Coating Technology

TriGard® coating for ResinDek® panels is the solution for tomorrow’s technology. TriGard® is specifically engineered and designed to handle the rigorous demands of ultra-high rolling traffic that is typically found in robotic applications. With significantly more wear and scratch resistance than Gray Diamond Seal® 2, TriGard® will outlast and outperform any mezzanine floor coating on the market!

  • Technology, Research and Innovation
  • Extreme long-lasting durability
  • Standard with ESD protection
  • Engineered to handle extraordinarily heavy wheel load traffic
ESD Finish
ESD - Electrostatic Dissipative Finish for Gray Diamond Seal® 2 and TriGard® Coatings

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.

Testing results are summarized as follows:

  • Average point-to-point resistance = 6.6 x 106 ohms
  • Average point-to-ground resistance = 7.8 x 106 ohms
  • ResinDek® mezzanine floor panels with ESD generated less than 10 volts with static controlled footwear, and experienced a rapid voltage decay from 5,000 volts to less than 50 volts in under .50 seconds
Collated Stand Up Screw Gun
Top Side Drill Screws

For conventional top side screw installation, use Cornerstone Specialty Wood Products, LLC® Collated Standup Screw Gun and collated drill screws. Not only will the collated screw gun save you up to 40% in fastening costs, but it will reduce installation fatigue with its ergonomic design.

The screws are engineered for strength, durability and easy installation. No coutersinking or pre-drilling is required as the wings are near the top of the shaft, which counterbore for screwheads. The number 2 square with a tek 3 drill point easily pierces up to 3/16” thick steel decking and is designed to drill through wood and steel decking prior to the threads engaging, thus preventing the panels from lifting.

In addition our collated screws offer the following advantages:

  • More consistent screw depth with greater control and settings
  • Fast and easy bit tip replacements
  • Requires minimal training
  • Stout # 12 gauge screw
  • Double winged part
  • Zinc coating for high humidity environments resists corrosion
  • Your choice of gray or beige drill screws
Invis-Loc Fastening System
Invisi-Loc® Underside Fastening Systems

Invisi-Loc® provides showcase mezzanine floors with no visible fasteners that are dependable, economical and easy to install. The Invisi-Loc® fastening system mounts fasteners under the mezzanine decking hiding unwanted screw holes on top.

  • 20 Invisi-Loc® fasteners are required per 4' x 8' sheet. A pneudraulic installation tool and a standard medium duty air compressor supplies the required power.
  • All pneudraulic installation tools can be rented or purchased from Cornerstone Specialty Wood Products, LLC®.
