PRODUCT DETAILS
1.5" Steel Form Deck (commonly designated in North American engineering specifications as 1.5F, Type F Form Deck, or 1.5" Non-Composite Deck) is a structural corrugated steel panel designed exclusively to serve as a high-strength, permanent stay-in-place formwork for poured concrete floor slabs.

Unlike 1.5" composite floor decks, 1.5" form deck features a smooth surface profile with no interlocking mechanical embossments . Since the steel sheet does not achieve a composite bond with the cured concrete, it cannot be calculated as tensile reinforcement for the long-term slab design load . Its core purpose is to provide the legal structural capacity to support the heavy weight of wet concrete and construction personnel during the pouring phase, while the final floor strength relies entirely on internal conventional rebar or welded wire mesh.

Engineering Notes |
|
Material Thickness (Gauges) |
22, 20, 18, 16 Gauge |
Heavier gauges (18 and 16GA) are heavily specified to maximize span spacing without bowing . |
|
Steel Grade |
Grade 40 to Grade 80 structural steel |
High yield points effectively control structural deflection under the weight of fluid concrete . |
|
Standard Finishes |
G60 / G90 Galvanized or Unpainted (Black Steel) |
Galvanized finishes provide permanent corrosion protection, while black steel is used only for temporary applications . |
|
Venting Options |
Solid or Vented Slots |
Vented profiles feature small slotted perforations in the bottom flutes to let excess hydration moisture escape downward . |
