Which Florida Codes Apply to Type B Metal Deck?
Type B deck in Florida is governed by the Florida Building Code: its structural chapters set dead, live and wind loads, its steel provisions reference AISI and SDI design standards, and its roofing chapter covers the roof assembly. Miami-Dade and Broward fall in the High-Velocity Hurricane Zone, with added requirements and product approvals. Ask us for the documentation your permit requires.
Structural requirements
- Design loads, including wind uplift by roof zone, are calculated per the code's structural provisions.
- Deck capacity is checked with AISI S100 and ANSI/SDI standards; our catalog data follows ANSI/SDI RD-2017, C-2017, NC-2017 and SD-2022.
- The deck also acts as a roof diaphragm, so fastening to supports and at sidelaps is part of the structural design.
Roofing and HVHZ requirements
The roof covering, insulation and their attachment to the deck form a roof assembly that must meet the code's roofing provisions. In the HVHZ, roof assemblies and components typically need approvals specific to that zone, and the permit reviewer will look for them. Product approval requirements vary by component and jurisdiction, so confirm with the building official and the roofing system manufacturer.

Related Questions
Who is responsible for Florida code compliance on the deck?
The engineer of record designs the deck, gauge and fastening for code loads; the contractor installs per the approved drawings; the building official reviews and inspects. As supplier, we provide product data and shop drawings that support that process. Ask us for the documentation your permit requires.
What is the HVHZ?
The High-Velocity Hurricane Zone is the part of Florida, Miami-Dade and Broward counties, with the code's most stringent wind provisions. Roof assemblies there face extra testing and approval requirements. Confirm what your project needs with the building department. Plan for it at bid time.
