Local Composite Floor Decks supply for Miami
Miami Metal Deck supplies Composite Floor Decks to contractors, erectors and fabricators building in Miami and across Miami-Dade County and the South Florida region. Because Miami is in South Florida, stock items can be picked up the same day at our Miami Gardens facility or delivered the same day to your site.
With Miami's coastal humidity and salt air, many engineers specify a G90 galvanized finish for its heavier zinc coating; we confirm the finish against your project specifications. Projects in Miami are designed to the Florida Building Code's High-Velocity Hurricane Zone (HVHZ) provisions for Miami-Dade County, so we work directly from your engineer's deck schedule and attachment details.

Frequently Asked Questions
Do you deliver composite floor deck to Miami?
Yes. We deliver to Miami and serve all of Florida with same-day or next-day delivery for most orders.
What spans can composite deck achieve?
Depending on gauge and profile depth, composite deck spans 6–15 feet unshored. We provide span tables and shop drawings for your specific project.
What does composite floor deck mean?
It is a steel deck profile made to work compositely with concrete. Embossments on the steel create a mechanical bond with the concrete, forming a structural slab in which steel and concrete share the load.
How is composite deck different from form deck?
Composite deck stays in place as a permanent structural element of the finished floor, with steel and concrete carrying loads together. Form deck is temporary, and the concrete alone carries the load once cured.
How far can composite floor deck span?
Depending on gauge and profile depth, unshored spans reach 6 to 15 feet. Shored construction can reach longer spans. Our engineers supply span tables and calculations specific to your project.
Do I need shear studs with composite deck?
Shear studs are typically needed for composite action between the slab and the supporting steel beams. Between the deck and the concrete alone, the embossed profile supplies the mechanical connection.
