Q. How do I determine the best decking option for me?
We offer several decking options for a variety of needs and use cases. Below, we will list a few of our most popular options and some of their benefits.

  • Bar Grating: Bar Grating is a strong and reliable decking option which allows air and light to move through. Will your product be rolling on your mezzanine? This is something to consider as bar grating adds more resistance against pallet jacks and carts compared to other options.
  • Floor / Diamond Plate: Plating is a very safe and durable decking option that is sure to last. Manufactured from steel formed into a flat plate studded with a diamond tread, it provides a slip-resistant surface that carts and pallet jacks can roll across with ease.
  • Resin Deck: Resin Deck comes in a variety of different panel types and finishes which have different capacities, making these a versatile option. The flat surface of this style of decking ensures great ease for rolling product. This type of flooring is laid over a metal B-Deck and is typically the most worthwhile decking application.

Q. What does PSF mean?
PSF is an abbreviation for Pounds per Square Foot, and is a measurement of uniform load capacity across your mezzanine. A standard mezzanine will generally support 125 pounds per square foot (PSF), but a variety of different materials can be used to increase the overall PSF limit of your mezzanine, making it more capable of handling heavier loads. Design load is the load in PSF averaged over the entire surface rather than a single heavy area on the structure known as a point load. Knowing the difference is essential when designing a safe mezzanine.

Q. Is there a minimum clear height for my mezzanine?
The minimum clear height under a mezzanine is usually at least 7'. This is also the same clear height between the decking of the mezzanine and the ceiling of your warhouse. Items to take into account when determining the clear height include positioning of lighting, sprinklers, and other obstructions in addition to any other items of concern as your jurisdiction evaluates.

Questions our sales team may review with you include:

  • What is the structure being used for?
  • What will be on top of the structure?
  • Will material on the mezzanine be moving regularly or stored long term?
  • Is the area dry?
  • Will the mezzanine be used for an inplant office?
