Ordered Monday evening, delivered Wednesday morning.
Unbelievable service and accountability. On top of every detail. Ordered Monday evening, delivered Wednesday morning. Only problem is they were earlier than I expected (not a problem). The delivery people were fantastic. All companies should be like this one.

What does a square of decking mean?
A “square” of decking refers to 100 square ft of any type of decking.
What is the difference between a form deck and a composite deck?
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.
What's structural deck's galvanized coating thickness?
Our galvanized decking is G40 which has a designated coating of .40 oz/square foot.
