Steel offers the optimal combination of strength, weight, span capability and cost.
Composite Floor Deck Roll Forming Process
The production sequence involves:
- Loading a steel coil into the feed system
- Feeding the strip through progressive roll forming stations
- Gradually cold-forming the target deck profile
- Punching any required holes for utilities or installation
- Shearing the deck sheets to specified length
- Conveying finished deck sections for stacking
Automated servo-motor controls precisely coordinate material movement through the in-feed, forming, punching, shearing and exit conveyor for rapid production.
