About 1.5" B-Deck
1.5" B-Deck
B-Deck is the standard structural steel roof and floor deck panel for commercial and industrial construction. Metal Warehouse Inc. stocks 1.5" B-Deck in multiple gauges for contractors across North Texas and Southern Oklahoma.
1.5" B-Deck (also called Type B deck) is a corrugated structural steel panel with 1.5-inch rib height and 36-inch coverage width. It is designed to span between structural framing members and serve as the base for built-up roofing systems or composite concrete floor slabs. B-Deck is engineered for structural load capacity, not just weather resistance.
