What Customers Are Saying

Our team is dedicated to provide on time deliveries every time. Your project deadlines are as important to us as they are to you.

In today's world of supply chain issues I have come to expect disappointment when ordering building materials. Not so with Structure Deck. I placed the online order on a weekend, received an email first thing Monday morning confirming the order. That was followed up with a phone call to see if they could deliver that same week. And to top that off their pricing was on point for a custom cut to length product even compared to my local supply house on stock lengths. 5 stars all the way around. I will definitely use them again.

We needed a quick turnaround on B Decking for the canopy over the main entrance at Grand Design’s new Customer Support Center… [Structural Deck] was able to deliver the material within 2 days of my order and kept our project on schedule.

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.

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

We recommend that 22ga B Deck be used for roof decking only. This gauge is not optimal for mezzanine decking applications, especially when fastening wood flooring with screws, due to this lighter gauge.

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

While some of our customers attach their decking using self-tapping screws, on larger projects we highly recommend that you consider the Hilti nailer method. It works great in both bar joist and beam structures. We would be happy to set you up with purchase or rental of this equipment. Thousands of fasteners are on our shelf.

Installer Fasten Metal Decking Using Hilti Nailer

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"

How long do you want it? You can choose a custom length between 3'-35' with 1" increments. We will roll form and cut it right to your specs.

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.

We offer 1-1/2" B-Decking in either 20 or 22 gauge which is commonly used for commercial roofing applications spanning across purlins, joists, or other support members.
