Type BI inverted form deck in Lakeland for architectural ceilings and exposed underside applications in schools, offices, and commercial buildings.

Type BI Inverted Form Deck for Lakeland job sites
General contractors and steel erectors in Lakeland rely on Miami Metal Deck for Type BI Inverted Form Deck on projects across Polk County and the Central Florida region. We ship to Lakeland from Miami Gardens, offering 1-day service to major Florida cities and coordinating freight with your site schedule.
For inland Lakeland projects, G60 galvanized is often sufficient for enclosed structures, while G90 remains available where the specifications call for more corrosion protection. Projects in Lakeland follow the Florida Building Code wind-load requirements, so we work directly from your engineer's deck schedule, gauges and attachment details.

Type BI Inverted Form Deck
Type B Inverted Form Deck is permanent formwork for concrete slabs in floor and roof systems, offered in gauges 22 GA through 16 GA. It was designed for architectural ceilings where the soffit stays exposed, and Lakeland schools, offices, and commercial buildings are typical uses.
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. |
The gauge lineup for Type BI Inverted Form Deck is 22, 20, 18, and 16. Standard commercial applications suit the lighter gauges (22 and 20). When you need more strength for parking structures or heavy industrial floor systems, use gauges 18 and 16.
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
High-strength steel makes up our Type BI Inverted Form Deck. Order it galvanized for corrosion resistance to ANSI/SDI standards, with one of many painted finishes for tailored aesthetics, or as bare steel when the application is custom. Every finish aims to build durability and sustain performance.
Custom lengths
Lengths begin at 6′-0″ for smaller projects and extend to 40′-0″ for larger ones. We supply the dimensions you specify, so the deck fits well and offcuts stay minimal.
Type BI Inverted Form Deck features
Type BI Inverted Form Deck brings high structural strength, efficient formwork, and corrosion-resistant finishes to architectural ceilings, multi-level parking structures, and commercial floor systems that require exposed soffits.
High Structural Strength
It carries concrete and live loads, and the underside becomes an architecturally finished exposed ceiling.
Efficient Formwork
Because the deck stays in place as permanent formwork for concrete slabs, labor and construction time drop and temporary forms never need removing.
Corrosion Resistance
For lasting corrosion resistance in commercial environments, choose G60/G90 galvanized or prime-painted finishes.
Cost-Effective
By combining formwork with structural support, it lowers material and labor costs where ceilings are left exposed.
Compliance with Standards
Conforms to SDI and ANSI guidelines for quality and code compliance in all applications.
Versatile Options
Gauges from 22 to 16 GA and multiple finishes are available to meet varying load and architectural needs.
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
- Deck is secured to supports with pins or powder-actuated fasteners
- #10 TEK screws at 6" o.c. on edges
- Sidelaps are attached with 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
Strong support for industrial floor systems plus an architecturally finished exposed soffit, which suits schools, offices, and civic buildings.

Multi-Level Parking Structures
A frequent choice for parking garages, giving permanent formwork and a clean exposed underside that cuts finishing costs.
Standards and product documentation
Type BI Inverted Form Deck meets SDI (Steel Deck Institute) specifications and ANSI standards, supporting solid design and performance on Lakeland jobs.
Type BI Inverted Form Deck questions
What is Type BI inverted form deck used for?
Architectural ceiling systems, multi-level parking structures, schools, offices, and any facility where an attractive exposed soffit is wanted.
How does installing Type BI differ from standard form deck?
Type BI is laid inverted with the ribs up. That leaves the flat side exposed below as a finished ceiling, with no extra finishing materials.
Which gauges does Type BI come in?
22, 20, 18, and 16 GA, giving options for different structural requirements.
What finishes does Type BI come with?
G60 and G90 galvanized finishes resist corrosion, and prime-painted finishes provide extra protection.
Can I get Type BI cut to length in Lakeland?
Yes, custom lengths from 6'-0" to 40'-0" are available, ensuring a precise fit and minimal waste.
