Optional finishes for heavy equipment and more banner



Warehouse mezzanine flooring must withstand the rigorous demands of heavy-duty equipment such as rolling carts and pallet jacks. Choosing the right flooring finishes and floor panel is important in maintaining the integrity of the floor surface, ensuring the safety of workers, and prolonging the life of the equipment.

Cornerstone Specialty Wood Products offers a variety of engineered mezzanine flooring surfaces for ResinDek panels that are specifically designed to withstand the movement of heavy rolling pallet jacks. With its superior strength, durability, and slip resistance, ResinDek's panels and heavy-duty flooring finishes provide a reliable solution for maintaining the safety and efficiency of your warehouse operations.


Gray Diamond Seal® is the standard by which all other coatings in our industry are measured. This superior finish is designed and engineered for heavy rolling pallet jack traffic. With its excellent wear, slip resistance and exceptional resistance to common stains, ResinDek® with the Gray Diamond Seal finish will look beautiful with a showcase appearance year after year. If electrostatic dissipative (ESD) is required be sure to request Gray Diamond Seal ESD.

Gray Diamond Seal proprietary coating has been tested in accordance with the following standards:

  • Stain Resistance: NEMA LD 3.4 with 29 different reagents
  • Wear resistance: ASTM D4060 (Taber abrasion)
  • Slip resistance: ASTM A326.3 Coefficient of Friction
  • Scratch resistance: Hoffman Scratch Hardness Tester
  • Gouge resistance: ASTM D2197


With our electrostatic dissipative finish, ResinDek® floor panels with Gray Diamond Seal ESD coating provides controlled dissipation and grounding of triboelectric charges with direct pathways of statically generated charges. The intentional flow of electrical current and discharge helps to immensely eliminate the potential of accidental electrostatic discharge, which can damage sensitive equipment. ESD limits the discharge to under 50 volts.

ResinDek panels with ESD comply with the following ANSI/ESD Association specifications:

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

Testing results:

  • 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


MetaGard GVT is a galvanized steel that encapsulates the top and sides of the ResinDek® panel. It is fused to the ResinDek panel with a proprietary bonding agent. 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. MetaGard GVT is the perfect flooring solution for heavy wear areas such as drop zones, pallet and case flow modules, or any other area where aggressive dragging or pulling exists. For a cost-efficient flooring solution ResinDek with MetaGard is engineered to provide a smooth panel to panel transition when installed next to other ResinDek panels that do not have a steel surface.

MetaGard GVT has been tested in accordance with the following standards:

  • Dynamic coefficient of friction: ASTM A326.3I
  • Wear resistance: ASTM D4060 (Taber abrasion)
  • Gouge resistance: ASTM D2197


UF provides a skid resistant surface and installs easily over corrugated metal B-decking with our recommended top side screw fastening systems. The uncoated ResinDek UF, moisture resistant flooring panel is priced competitively and will never delaminate. Plus, unlike plywood, OSB or other engineered wood products, ResinDek UF flooring panel has a 10-year product warranty.
