Local Type BI Inverted Form Deck supply for Fort Lauderdale
Builders in Fort Lauderdale order Type BI Inverted Form Deck directly from Miami Metal Deck for commercial and industrial projects throughout Broward County and the South Florida region. Because Fort Lauderdale 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 Fort Lauderdale'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. Broward County falls within the Florida Building Code's High-Velocity Hurricane Zone (HVHZ). Send us the deck and attachment requirements on your drawings so we can supply the specified gauge and lengths.

Type BI Inverted Form Deck
Architectural ceilings with an exposed soffit are what Type B Inverted Form Deck is designed for. It works as permanent formwork for concrete slabs in floors and roofs, in gauges 22 GA through 16 GA, and is a natural fit for Fort Lauderdale commercial and institutional buildings.
Dimensions and profile

| Property | Dimension |
|---|---|
| Profile Depth | 1.5 inches |
| Coverage Width | 36 inches |
| Rib Spacing | 6 inches (center to center) |
| Rib Height | 1.5 inches |
Type BI Inverted Form Deck has a 1.5-inch rib depth and a standard 36-inch coverage width. Ribs face upward when it is installed, so a smooth, flat soffit shows below and works as an architectural ceiling with no added finish. Rib spacing of 6 inches (center to center) keeps the structure sound and still accommodates concrete placement.
Gauges and thicknesses
| Gauge | Bare steel thickness (in) | Weight (lbs/sq ft) | Typical applications |
|---|---|---|---|
| 22 | 0.0299 | 1.25 | Light-duty floors and ceilings. |
| 20 | 0.0358 | 1.5 | Standard commercial floor systems. |
| 18 | 0.0474 | 2.6 | Heavy-duty applications, parking structures. |
| 16 | 0.0598 | 3.0 | Heavy load industrial floors. |
Type BI Inverted Form Deck is produced in gauges 22, 20, 18, and 16. Gauges 22 and 20, the lighter ones, are ideal for standard commercial applications, while 18 and 16 add strength for parking structures and heavy industrial floor systems.
Finishes and coatings
| Finish | Details |
|---|---|
| Galvanized G60 | Zinc coating of 0.6 oz/ft². Recommended for general environments. |
| Galvanized G90 | Zinc coating of 0.9 oz/ft². Ideal for highly corrosive environments. |
| Prime-Painted | Provides a base coat for additional protection or paint adhesion. |
| Bare Steel | Unfinished; typically for indoor use or controlled environments. |
Type BI Inverted Form Deck is offered with galvanized (G60 and G90) and prime-painted finishes. The galvanized coatings protect against corrosion, with G90 extending that protection to highly corrosive environments. G60 and G90 finishes conform to ASTM A653 specifications.
Material and finish options
Type BI Inverted Form Deck is high-strength steel and can be ordered with a corrosion-resistant galvanized finish that meets ANSI/SDI standards, in a range of painted finishes for tailored aesthetics, or as bare steel for custom applications. Each finish is meant to improve durability and keep performance consistent.
Custom lengths
We cut deck from 6′-0″ for smaller projects up to 40′-0″ for larger constructions. Our custom length service follows your requirements to deliver an optimal fit with minimal waste, whatever the size of the job in Fort Lauderdale.
Type BI Inverted Form Deck features
Type BI Inverted Form Deck offers high structural strength, efficient formwork, and corrosion-resistant finishes. It fits architectural ceilings, multi-level parking structures, and commercial floor systems that need exposed soffits.
High Structural Strength
Carries concrete and live loads and also gives you a finished, exposed ceiling surface.
Efficient Formwork
As permanent formwork for concrete slabs, it saves labor and construction time because no temporary forms need to be removed.
Corrosion Resistance
G60/G90 galvanized or prime-painted finishes hold up against corrosion in commercial environments.
Cost-Effective
One product handles both formwork and structural support, which lowers material and labor costs for exposed ceilings.
Compliance with Standards
SDI and ANSI guidelines are met, so quality and code compliance carry across applications.
Versatile Options
A choice of gauges (22–16 GA) and finishes covers different load requirements and architectural specifications.
Installation and connections
Installation practices
- Install the deck with ribs facing up, perpendicular to the supports.
- Fasten at every support with pins, powder-actuated fasteners, or TEK screws.
- Overlap sidelaps and fasten with button punching or screws at 12" o.c.
Fasteners and attachments
- Pins or powder-actuated fasteners hold the deck to the supports
- #10 TEK screws at 6" o.c. on edges
- Sidelaps fastened using button punching or #10 TEK screws at 12" o.c.
Confirm the profile, gauge, span, loads and connections against your project drawings and the applicable product load tables before ordering.
Applications

Industrial Flooring with Exposed Ceiling
Industrial floor systems get strong support, and the soffit below is architecturally finished and exposed. It is a good match for schools, offices, and civic buildings.

Multi-Level Parking Structures
Parking garage construction commonly uses it. It supplies permanent formwork and leaves a clean exposed underside, which reduces finishing costs.
Standards and product documentation
SDI (Steel Deck Institute) specifications and ANSI standards apply to Type BI Inverted Form Deck, which supports high standards of design and performance.
