Type B Metal Deck for Florida Distribution Centers
1.5" Type B is the go-to roof deck for Florida distribution centers. Its 36" coverage and wide rib suit huge roofs over joists and joist girders. On roofs this size, logistics matter as much as the deck: accurate takeoffs, cutting lists that limit waste, and deliveries sequenced to the erection plan. We provide all three, plus G60 or G90 in 22 to 16 gauge.
Estimating a large roof
Estimate total deck weight as: roof area (sq ft) x design weight (psf) x (1 + waste factor). Catalog design weights are 1.6 psf at 22 gauge, 2.0 at 20, 2.6 at 18 and 3.0 at 16. Weight affects steel cost, the number of loads and crane picks. Cutting lists built from shop drawings reduce the waste factor.
Perimeter and corner zones usually need heavier fastening or gauge for Florida wind uplift. Separate them in the takeoff so bundles land in the right place.
Logistics that save time
- Bundles tagged by area and sequence, set to the erection plan.
- Custom cut lengths matched to joist bays to cut field trimming.
- Accessories (sump pans, closures, Tek screws) in 10' lengths, ordered with the deck.
- Joists and joist girders sourced to SJI standards alongside the deck.

Related Questions
Is 22 gauge Type B enough for a distribution center?
Sometimes, if joist spacing and uplift allow. The catalog's 22 gauge single-span construction span is 8'-03", and 10'-02" for double or triple spans. Many large roofs use 22 gauge in the field and heavier gauges at edges and corners. The engineer's deck schedule decides.
Can deck and joists come from one supplier?
Yes. We supply steel deck and source K, LH and DLH joists and joist girders to SJI standards, so one takeoff and one delivery plan cover the roof structure. Joist design remains with the joist designer and engineer of record.
