Specifications of Type S Form Deck
Key details on strength, gauge, finish, and depth for the Type S form deck
Dimensions and Profile Details
| Property | Details |
|---|---|
| Profile Depth | 9/16 inches |
| Coverage Width | 36 inches |
| Rib Spacing | 2.57 inches (center to center) |
| Rib Height | 9/16 inches |
The Type S Form Deck features a shallow 9/16-inch rib depth and a standard coverage width of 36 inches, making it ideal for rapid concrete slab forming. Its rib spacing of 2.57 inches (center to center) provides a stable forming surface that minimizes concrete volume while ensuring structural integrity.
Gauge
| Gauge | Bare Steel Thickness (in) | Weight (lbs/sq ft) | Typical Applications |
|---|---|---|---|
| 28 | 0.0149 | 0.65 | Light-duty concrete formwork, low-load applications. |
| 26 | 0.0179 | 0.75 | Standard concrete slabs. |
| 24 | 0.0239 | 1.0 | Medium-duty floor and roof slabs. |
| 22 | 0.0299 | 1.25 | Medium-duty floors, multi-level buildings. |
| 20 | 0.0358 | 1.5 | Heavy-duty formwork, bridges. |
The Type S Form Deck is available in gauges 28, 26, 24, 22, and 20. Lighter gauges (28 and 26) are cost-effective for standard concrete slabs. Heavier gauges (22 and 20) provide superior strength for longer spans and heavier concrete loads in demanding applications like bridges and industrial floors.
Finish
| Finish Type | 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. |
The Type S Form Deck comes in galvanized (G60 and G90) and prime-painted finishes. Galvanized coatings offer corrosion resistance, with G90 providing extra protection for highly corrosive environments. G60 and G90 finishes conform to ASTM A653 specifications.
Installation

FAQ
FAQs About Type S Form Deck
What is the purpose of Type S form deck?
Type S form deck serves as permanent formwork for concrete slabs in floor and roof systems, providing a stable base during concrete placement and remaining in place after curing.
What is the difference between form deck and composite deck?
Form deck acts only as formwork the concrete slab carries the load independently after curing. Composite deck bonds structurally with the concrete to share load permanently.
What gauges are available for Type S form deck?
Available in gauges 28, 26, 24, 22, and 20 GA with thickness ranging from 0.0149" to 0.0358".
What fastening methods are recommended?
Type S Form Deck is attached using pins, powder-actuated fasteners, or TEK screws. Sidelaps are secured with button punching or #10 TEK screws at 12" o.c.
Can Type S form deck be cut to custom lengths?
Yes, available in custom lengths from 6'-0" to 40'-0", minimizing material waste and ensuring a precise fit for each project.
