Heavy Duty Metal Deck Roll Former Cold Roll Forming Machine Automatic Steel Floor Decking Profile Panel Production Line Equipment with Twin Motor Drive Hydraulic Post Cut PLC Digital Control System for Composite Concrete Floor Slab Structural Steel Building Manufacturing
This heavy-duty metal deck roll former is purpose-built for continuous in-line production of open-type trapezoidal steel floor decking panels — the most widely specified deck profile in multi-story steel-frame construction worldwide. Each finished panel functions as permanent formwork during concrete pouring and as bonded tensile reinforcement after the slab cures, enabling faster floor cycles and reduced structural steel tonnage compared to traditional timber formwork methods.

Deep-rib floor deck forming generates extreme friction between the steel strip and roller surfaces. Without active anti-pooling measures, material bunches inside the forming zone — scratching panels and halting production. This machine integrates five synchronized devices to prevent that:
| Stage | Device | Location | Function |
|---|---|---|---|
| 1 | Clutch-Controlled Dimple Wheel | Immediately after dimple embossment station | Disengages dimple wheel drive after material entry; downstream rollers carry the sheet forward at correct linear speed, preventing overspeed jamming |
| 2 | Bearing-Mounted Oversized Rear Rollers | Final 10 forming stations | Internal-bearing design converts roller action from pulling to pushing; eliminates surface scratching on finished rib flanks |
| 3 | Pressure Reinforcement Bars | At dimple station, main drive row, rib-forming rows, and sizing rows | Increases effective shaft leverage force — Φ95 shaft performs equivalent to Φ100 under load; ensures flat, unwarped panel surface |
| 4 | Gear Drive Boosters | Dimple row entry, front of oversized wheel section, exit sizing rows | Boosts material feeding and pulling torque at the highest-resistance points in the forming sequence |
| 5 | Dual-Cylinder Floor Shear | End of forming line, floor-mounted | Balanced hydraulic cutting force across full panel width; floor-level positioning allows finished panels to stack by gravity without manual handling |
| Step | Station | Operation |
|---|---|---|
| 1 | Decoiler Pay-Off | 5-ton hydraulic mandrel feeds galvanized coil strip into leveling guide |
| 2 | Entry Guide & Leveling | Side rollers center the strip; leveling rollers remove coil set curvature |
| 3 | Dimple Embossment | Clutch-controlled embossing wheel stamps bond pattern into rib surfaces |
| 4 | Progressive Forming (Rows 1–12) | Gradual trapezoidal rib shaping — each row deepens the profile incrementally |
| 5 | Deep Rib Forming (Rows 13–22) | Final rib depth achieved; oversized bearing-mounted rollers push material through |
| 6 | Sizing & Straightening (Rows 23–30) | Precision sizing rollers lock final profile geometry; straightening pass corrects camber |
| 7 | Hydraulic Cutoff | PLC triggers dual-cylinder floor shear at preset length; Cr12MoV blades cut clean |
| 8 | Output & Stacking | Finished panels gravity-drop onto run-out table; ready for bundling |
