Open Floor Deck Roll Forming Machine — Trapezoidal Steel Decking Production

The Open Floor Deck Roll Forming Machine is a heavy-duty cold roll forming line engineered to produce trapezoidal (open-type) steel floor decking panels. These panels serve as permanent formwork and tensile reinforcement in composite concrete floor slabs — widely used in steel-frame commercial buildings, industrial plants, multi-story car parks, and mezzanine structures.

What Is Open Floor Deck?

Open deck (开口楼承板) features a trapezoidal rib profile with exposed ribs on the underside. The concrete is poured directly onto the deck, bonding mechanically via embossed dimples on the rib surfaces. This is the most common floor deck type globally — cost-effective, proven, and suitable for standard-span applications.

Key Machine Specifications

• Dual 11KW Motors (2×8#) — Balanced twin-drive system ensures reliable forming through deep trapezoidal ribs without stalling.
• 450H Laisteel Main Frame — 10mm wing thickness I-beam construction, purpose-built for the high forming forces required by 0.8–1.5mm galvanized steel coil.
• Φ95–115mm Chrome-Plated Shafts — Precision-ground from 100mm round bar, heat-treated to HRC 45–50° for extended service life.
• 22–36 Forming Rows — Progressive roll forming with 2-inch heavy-duty chain drive; row count adjustable to match rib depth and material thickness.
• 5-Stage Anti-Pooling System — Clutch-controlled dimple wheel + bearing-mounted oversized rear rollers + pressure bars + gear drive boosters + dual-cylinder floor-standing hydraulic shear. Eliminates material jamming during deep-rib forming.
• Dual-Cylinder Floor Shear — Balanced hydraulic cutting with gravity-assisted panel stacking, no manual lifting required.
