Q: Why are your panels undersized?
A: We manufacture the panels 1/8" under nominal dimensions to allow for gapping. When spaced properly, a nominal 4x8 panel will take up exactly 48" x 96" of space on your platform.

Q: Why do I need to gap ResinDek® panels?
A: ResinDek panels, like most other mezzanine floor panels in the industry, are prone to linear expansion during changes in humidity on the jobsites. Because ResinDek panels are extremely dense and don't crush under load, they are particularly susceptible to buckling if the panels expand into adjacent panel edges. Once maximum growth is achieved, the gaps rarely shrink and remain quite stable.

Please note that ResinDek panels with UF, Gray Diamond Seal 2, Gray Diamond Seal 2 ESD and TriGard ESD finished require the 1/8" gap. ResinDek panels with MetaGard finish do not need to be gapped. Please reference the ResinDek Installation Instructions for further details.

Q: When do I need a finish on my panels?
A: When you have high traffic and want a good-looking floor for years to come on your storage mezzanine floors and mezzanine platform floors. Without a finish, stains from beverages, marking pens, and traffic penetrate the panels and are not easily removed.

Q: Can you apply a finish to ResinDek UF (unfinished) after it has been installed?
A: While not as durable as our factory coating options, ResinDek UF can be painted onsite. Sherwin-Williams offers a wide range of two-part coating options, please contact our office for additional details.
Q: Can you help me with Fire Code Issues?
A: Code compliance for ResinDek panels installed over steel deck can be found in the following Evaluation Service Reports: Fire Compliance.

  • ResinDek® LD 2.8 lbs. / sf.
  • ResinDek® SD 3.1 lbs. / sf.
  • ResinDek® MD 3.5 lbs. / sf.
  • ResinDek® HD 3.8 lbs. / sf.
  • ResinDek® Xspan® 5.2 lbs. / sf.
  • ResinDek® Xspan® FR 6.0 lbs. / sf.
  • ResinDek® with MetaGard® LD 4.2 lbs. / sf.
  • ResinDek® with MetaGard® SD 4.5 lbs. / sf.
  • ResinDek® with MetaGard® MD 4.9 lbs. / sf.
  • ResinDek® with MetaGard® HD 5.2 lbs. / sf.
  • ResinDek® with MetaGard® Xspan® 6.6 lbs. / sf.
  • ResinDek® with MetaGard® Xspan® FR 7.6 lbs. / sf.

Q: What is more important - Uniform loads per square foot, or pallet jack loads?
A: While both are important, the loads imposed by pallet jacks are usually more critical because the load is more concentrated and dynamic instead of static. Pallet jack loads also appear to increase the risk of failure faster when recommended loads are exceeded.

Q: Do you warrant your panels?
A: All ResinDek panels are conditionally warranted for a period of ten years when installed and used within our guidelines. Please refer to our detailed Installation Instructions and written warranty for details.

Q: When should I use the ESD finish?
A: ResinDek with Gray Diamond Seal 2 ESD should be used whenever there is electrically sensitive equipment, including laptops, barcode scanners, and RFID devices on or around your mezzanine platform floors. In addition, ResinDek ESD panels eliminate the occasional static shock that your personnel may occasionally experience when walking on a floor in dry environments.

ResinDek with TriGard ESD has all the benefits above, but is also designed to handle the rigorous demands of ultra-high rolling traffic typically found in robotic applications.

Q: Why do I have to use your ResinDek Drill Screws instead of my own?
A: You can use your own screws, but we cannot warrant against fastener related issues if you do. Our screws are self-drilling, require no counter-boring, and are computer color matched to the panel surface. Problems frequently encountered with other screws include strip out, improper seating of the screw head, and panel lift from the surface of the corrugated. Pre-drilling may be required on ResinDek Xspan installed over heavy gauge steel. Cornerstone Specialty Wood Products, LLC® for further details.

Q: What is the Invisi-Loc® Underside Fastening System?
A: The Invisi-Loc Underside Fastening System is an advanced fastener installation system that mounts fasteners under the mezzanine decking rather than on the top. Our patented underside fastening provides a showcase appearance floor that is easier to clean.

Q: What is the standard unit size for ResinDek Panels?
  • ResinDek® LD 36 pcs. per unit
  • ResinDek® SD 32 pcs. per unit
  • ResinDek® MD 32 pcs. per unit
  • ResinDek® HD 32 pcs. per unit
  • ResinDek Xspan® 21 pcs. per unit
  • ResinDek Xspan® FR 21 pcs. per unit

Q: What is the best way to repair ResinDek panels?
A: ResinDek mezzanine floor panels can be repaired and touched up using our ResinDek Touch up coating and Resin repair compound filler. Please see our "Care and Maintenance Instructions" for details.

Q: How thick are ResinDek panels?
A: ResinDek LD, MD and HD are 3/4" thick. Our 3/4" thick panels are designed to install over 20 gauge "B" decking. 18 gauge "B" decking is recommended for 2,500 lb. loads or greater. ResinDek Xspan is 1-1/8" thick designed to be installed directly over bar joists or structural supports without "B" decking.
