N Deck Roll Forming Machine Technical Data Sheet
Machine Overview
Parameter Specification
Machine Name N Deck Roll Forming Machine
Profile Produced N Deck Structural Steel Deck Panels
Machine Type Single profile roll forming machine
Production Application Steel floor decking systems, composite concrete floors
Manufacturing Process Continuous cold roll forming
Production Environment Factory production line / steel building manufacturing facility
The N deck roll forming machine produces deep rib steel decking panels used in composite floor systems and structural steel buildings. N deck panels have deeper ribs than standard B deck, providing increased load capacity for long span floor systems.
N deck is commonly used in commercial buildings, industrial structures, and high-rise construction where greater structural strength is required.
