Type B Metal Deck for Florida Self-Storage Facilities
1.5" Type B deck works well on Florida self-storage roofs, both single-story drive-up buildings and multi-story climate-controlled facilities. In multi-story buildings the upper floors use composite floor deck. Drive-up units are unconditioned and humid, so G90 galvanized is a sound choice. Repeating bays make cutting lists efficient. We supply roof and floor deck together.
Deck by building type
- Single-story drive-up: Type B roof deck over joists or purlins. G90 suits unconditioned interiors.
- Multi-story climate-controlled: Type B on the roof and composite floor deck (1.5", 2" or 3") on upper levels.
- Framing: steel joists or C and Z purlins, and we supply both.
- Loading canopies: open exposure, so G90.
Why storage jobs suit pre-cut deck
Storage buildings repeat the same bay many times. A takeoff with standard cut lengths turns into a simple cutting list, less waste and fast installation across identical buildings.

Related Questions
Is Type B used for the floors of multi-story storage?
No. Floors carry concrete, so they use composite floor deck, sized by the engineer for the storage live load. Type B is used only for the roof. We supply both, so the whole building can be priced from one takeoff.
Can Type B span between purlins on a storage building?
Yes, when the purlin spacing is within Type B's spans for the design loads. C purlins come in 12 to 20 gauge and Z purlins in 12 to 18 gauge, at 55 ksi. The engineer sizes purlins and deck together.
