1.5B & 3B Steel Deck Roll Forming Machine | Best Machinery - Changzhou, China

1.5B and 3B Steel Deck Roll Forming Machine for North America by Cangzhou Best Machinery

The Cangzhou Best Machinery steel deck roll forming machine produces galvanized steel roof and floor deck in the 1.5-inch B-deck and 3-inch deck profiles used across the US and Canadian construction markets. It is a heavy-duty, 13-ton machine with 95 mm shafts, a 22 kW chain drive, hydraulic cutting, and PLC control, forming deck at 10 m/min (about 33 ft/min) from 1250 mm wide galvanized coil. It is built by Cangzhou Best Machinery in Cangzhou, Hebei, China.

What Is 1.5B and 3B Steel Deck?

Steel deck is corrugated galvanized sheet used as the structural base for roofs and concrete floors in steel-framed buildings. In North America, the most common profile is 1.5-inch B-deck, also called wide rib deck, which has 1.5-inch deep ribs spaced 6 inches apart and covers 36 inches per sheet. It's the standard roof deck for commercial and industrial buildings, and composite versions are used under concrete floor slabs. Deeper 3-inch deck spans farther between supports, so it's used where beams or joists are spaced more widely. Deck profiles in the US and Canada are generally designed to Steel Deck Institute (SDI) and Canadian Sheet Steel Building Institute (CSSBI) standards.

How the Machine Works

1. Decoiling. The galvanized steel coil is loaded onto the decoiler and fed into the machine.

2. Roll forming. Chain-driven forming stations with 95 mm shafts and 45# steel rollers shape the strip progressively into the deck profile, with even pressure across the full width.

3. Hydraulic cutting. A hydraulic cutter cuts each deck sheet to the programmed length.

4. PLC control. The operator enters sheet length and quantity on the PLC, and the machine forms and cuts automatically.
