Miami Metal Deck explains how optional configurations of Type B metal decking address the unique architectural and structural demands of South Florida. Type B metal decking South Florida requirements prioritize hurricane-level wind loads, salt-air corrosion resistance, thermal and acoustic control, and code-compliant fire performance. This article outlines configurable profile, coating, insulation, and fabrication options you can specify to optimize performance, cost, and long-term durability while meeting Florida Building Code and Miami-Dade Product Approval criteria.
Structural & Profile Variations
Engineers commonly choose from multiple flute depths, rib patterns, and gauge thicknesses for Type B metal decking to control span, stiffness, and concrete slab interaction. Options include shallow and deep flute profiles, 22 to 18 gauge steel, and embossed composite surfaces to improve shear transfer. Composite Type B assemblies with welded or mechanical shear connectors increase slab composite action for longer spans and lighter supporting framing.
Beyond profile, specify camber, pre-punched shear connector patterns, and stiffeners for concentrated loads or equipment zones. Non-composite and cellular variants serve architectural soffits or integrated MEP runs. All structural configurations can be supplied with engineer-certified span tables, mill certificates, and load calculations tailored to South Florida wind load and uplift requirements.
Corrosion Resistance and Coatings
Salt-laden air in South Florida demands enhanced corrosion protection. Available coatings include G60 and G90 galvanizing, Galvalume (aluminum-zinc) substrates, and duplex systems combining hot-dip galvanize plus epoxy or polyester topcoats. For coastal projects consider higher zinc coatings, aluminized steels, or factory-applied epoxy primers to extend service life and preserve warranty terms.
Specify coating systems to meet ASTM A653 and project longevity targets; Miami Metal Deck can provide test data, corrosion cycle expectations, and recommended maintenance intervals for coastal exposures. Choosing the correct coating reduces life-cycle cost and minimizes disruption from premature replacement.
Thermal, Acoustic, and Fire Options
Type B metal decking can be configured with integrated thermal breaks, rigid insulation inserts, or mineral wool layers to meet continuous insulation and energy code goals. Perforated deck options, isolated cavity insulation, and resilient channels improve acoustic isolation for residential and hospitality projects. Fire-resistance is achieved with rated deck-slab assemblies, cementitious spray fireproofing, intumescent coatings, or thicker concrete crowns to meet ASTM E119 and Florida Building Code requirements.
Roof and terrace applications can include tapered insulation over deck, waterproofing-ready profiles, and green roof-compatible decks. We document assembly ratings and testing evidence so architects can specify performance with confidence in South Florida climates.
Fabrication, Compliance and Value-added Services
Miami Metal Deck offers shop-fabrication options such as custom panel lengths, sheared and notched edges, factory-installed closures, curving for architectural forms, and punched openings for penetrations. We provide engineered submittals, shop drawings, Miami-Dade NOA coordination assistance, and QA/QC reports. Lead times, warranty terms, and installation support are detailed up front so owners understand cost, schedule, and risk.
