Our team at D-MAC Industries can help match an existing form deck or find a new form deck product that meets your needs. Use our online guide to match the dimensions of your current deck, which allows you to easily identify your steel deck with images and common manufacturer designations.
Storing and Handling 1 ½” Form Deck Products
It’s important to store 1 ½” form deck correctly to protect against corrosion, deformation, and other damage. All form deck products should be stored off the ground with one end elevated to allow for proper damage. Bundles must be protected against condensation with a ventilated waterproof covering. Decks should be covered with a waterproof tarp to be protected from snow, salt, and water.
Galvanized products are stored outside and may have oxidation on the surface. It’s important to note that this will not affect the structural integrity of the steel; however, if you are using a 1 ½” form deck for decorative use, you’ll want to take proper precautions to minimize oxidation.
Installation of 1.5″ Form Deck
D-MAC Industries always recommends that an experienced and qualified worker installs a 1.5” steel form deck. For the best outcome, form deck shall be placed in accordance with approved erection drawings, and deck sheets should be butted over supports. Install deck ends over supports with a minimum end bearing of 1 ½” or as indicated on the erection drawings.
