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 |
This 1.5" Type B metal deck has a 1.5 inch rib depth and a standard coverage width of 36 inches, which makes it structurally efficient for roofing and flooring. Ribs sit 6 inches apart (center to center), and the 39 inch overall material width gives secure overlaps and strong composite action with concrete slabs. The profile maximizes strength at minimal weight, so it works across many kinds of construction.
Gauges and thicknesses
| Gauge | Bare steel thickness (in) | Weight (lbs/sq ft) | Typical applications |
|---|---|---|---|
| 22 | 0.0295 | 1.6 | Light-duty roofing and small spans. |
| 20 | 0.0358 | 2 | Medium spans, roofing, and siding. |
| 18 | 0.0474 | 2.6 | Heavy-duty applications. |
| 16 | 0.0598 | 3 | Heavy load spans. |
There are four gauges to choose from for Type B deck: 22, 20, 18, and 16. Each has different thickness and load capacity, so you can fit the deck to the project. Light and cost-effective, 22 and 20 gauge are best on shorter spans and lighter loads. Stronger 18 and 16 gauge carry longer spans and heavier loads, which makes them ideal for demanding applications.
Finishes and coatings
| Finish | Details |
|---|---|
| Galvanized G60 | Zinc coating of 0.6 oz/ft². Recommended for general environments. |
