Mezzanine Flooring & Decking Options
There are several options for constructing a mezzanine floor, including the use of different types of decking materials. Some common options for mezzanine floor decking include steel, concrete, composite, and grating. The best decking material for a mezzanine floor will depend on the specific needs and requirements of the application. Factors to consider include the intended use of the space, the load-bearing capacity required, and the budget.
Standard Mezzanine Decking
Consists of one layer of 3/4" T&G, OSB (oriented strand board) installed over 1-1/2" deep gauge corrugated steel deck. OSB provides good resistance to foot traffic and can handle random wheel loads up to 300 lbs. The steel decking has a white underside to provide maximum light reflectance. Most economical selection for general storage and office applications.
Bar Grating – 1" x 1/8"
A strong and economical alternative, bar grating allows for air movement, light, and water from overhead sprinklers to pass through deck surface. Nominal 1" x 4" opening. Black finish is standard. Also available in a galvanized finish. Should not be used for pallet jack applications.
Steel Tread Plate Over OSB
Heavy-duty steel tread plate has a diamond embossed non-skid surface. OSB is 3/4" tongue and groove over a 20 gauge corrugated steel deck. Provides greater durability with higher point load and wheel load capacities.
Steel Tread Plate Over 20 Gauge Steel Roof Deck
Mezzanine flooring designed for projects that will not allow combustible materials, 12 gauge steel tread is provided directly over the steel roof deck. Steel tread plate is diamond-embossed for a non-skid surface. Top surface of tread plate can be shipped unfinished or painted. White underside of decking for light reflectance.
High Density Composite Flooring over 20 gauge steel deck
Recommended for mezzanines requiring a solid floor subject to heavy loads from the use of pallet jacks, carts or dollies. Flooring has an Acryseal skid-resistant, cleanable surface. Standard gray finish. Clear finish available at additional cost.
Concrete Mezzanine Deck
The strongest and most durable mezzanine surface available. Ideal when high point loading and capacity is required. Density minimizes transmission of noise through decking. Steel decking is provided with components needed to accept pour of 4-inch concrete floor.
