Frequently Asked Questions
Here are some of the top questions about metal decking material and ordering from Structural Deck.
View All FAQsWhat gauges (thickness) are available?
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″
In what applications should I choose white bottom over galvanized?
Our White Bottom decking is painted with a brilliant reflective paint similar to the coating on a light fixture. This is recommended when you want the bottom or underside of your structure to have maximum brightness for a work space.
Galvanized decking is generally less cost per square foot but gives the same rated capacity. This can be used for general construction when the decking is covered by a ceiling or the end user is not concerned about brightness.
Galvanized is also recommended for form deck applications as the concrete being formed has moisture and wants to cause premature rust on the decking.
How do I fasten the decking to my structure?
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.
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.
B-deck
FD (Form) Deck
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.

What is your return policy?
We do not accept returns due to all of the metal decking being cut to custom lengths.
What is Form 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.
