Form Deck Features

There are many benefits to using concrete floor on your mezzanine. Here's a list of 3 features that we believe are the most important.

Rock Solid

Many mezzanine floors use a wood or resin material. Not only can they feel spongy when loaded, they break down over time with heavy traffic and require replacement. That's why our form deck paired with concrete is simply the best option.


With rising costs of wood and resin options, concrete flooring has become more affordable than ever compared to other options on the market.

Type of Form Deck Material

We offer 20 and 22 gauge galvanized form deck. Since the decking ribs are 1 1/2" tall, we recommend a minimum of 3 1/2" total concrete depth, which makes a structurally sound floor.

Frequently Asked Questions

These are the common questions that come up about ordering, steel decking material, etc. If your question isn't answered send us a message.

B Deck

Form Deck

Our galvanized decking is G40 which has a designated coating of .40 oz/square foot.

Structural Deck only provides decking material. We do not offer any installation services.

Attaching decking is a time-consuming process that requires a good level of accuracy. While some of our customers choose to attach decking using self-tapping screws, we highly recommend using the Hilti nailer method, particularly on larger projects.

The Hilti Stand-up Handle enables workers to efficiently and accurately attach sheets of decking from an ergonomic upright position as opposed to bent over and manually screwing.

Screw Locations

Attaching B-deck and Form deck to either a structural steel beam or bar joist, we recommend using the Hilti DX-9 HSN and DX-9 ESP for each structural support respectively. Remember that you will need to use the appropriate fastener type in each application.



Screw Overlap

FD (Form) Deck

Screw Overlap

For attaching sheets of B-deck and FD (Form) deck with a Hilti Stand-up Handle, you must use the red strip Hilti #10 HWH screws to attach the sheets while standing on the upper decking panel. In the diagram, that means standing on the right side for B-deck and on the left for Form deck. Standing on the upper panel applies force to the overlap ensuring a clean connection.

To see authorized Hilti distributors and rental locations, visit Hilti's website.

It is recommended that all metal decking be shipped to the job site under a tarp and then stored out of the elements to avoid corrosion or surface rust.

This is especially important with White Bottom decking as surface rust from moisture shows up very quickly if left outside. We recommend that all decking be stored off the ground with one end elevated.

We have 20 and 22 gauge available for both B Deck and Form Deck. 20 gauge is .036" and thicker than 22 gauge at .030"

Composite Deck generally refers to a thin gauge, yet high yield strength decking that is designed to enhance the strength of the concrete being poured on top it.

Composite Deck has embossments in the metal designed to interlock and connect to the concrete as it is being poured which then adds to the strength of the floor structure as part of the design.

Here at StructuralDeck.com, we only offer Form Deck.

This deck simply has a standard smooth surface and is designed only to support the dead weight of the concrete while it is being poured, and then the concrete is self-supported.

Typically, a wire mesh product is used alongside Form Deck to reinforce the concrete to meet the engineered requirements.

We do not offer composite deck.

Form Deck is a reliable and affordable way to form concrete for floors in new construction typically on top of a mezzanine platform or covered pit application.

That answer isn't always the same. Check out our Form Deck Specs document for more details.
