The FX450 Heavy-Duty Automatic CZ purlin roll forming machine is engineered for high-capacity, heavy-gauge structural steel manufacturing. Capable of handling a web width up to 450 mm and material thicknesses up to 4.5 mm, the FX450 stands as Metoform’s most powerful, high-efficiency, and high-precision CZ interchangeable roll former.
Equipped with a fully automated PLC control system, it features a quick C/Z interchanging system that allows operators to switch profiles in just 3 steps (approx. 5 minutes). Additionally, the advanced universal post-cutting system eliminates the need to replace cutting blades when changing purlin sizes, significantly reducing downtime and maximizing workshop productivity.

FAQ
What is the maximum capacity of the FX450?
It handles material thickness up to 4.5 mm and web widths up to 450 mm, which makes it the most powerful C/Z interchangeable roll former in the Metoform lineup. It is built for heavy-gauge structural steel production.
How is the FX450 roll forming system driven?
By gear boxes, instead of the chain drive used on lighter models. The gear box drive delivers the torque needed to form thick, high-strength steel consistently, with forming speed up to 35 m/min.
What kind of de-coiler does the FX450 use?
A hydraulic automatic de-coiler with a 10-ton weight capacity. It feeds and uncoils heavy coils automatically, so the line does not need manual coil handling.
What steel grades can the FX450 process?
Cold rolled, hot rolled, and galvanized coil from 1.0 mm to 4.5 mm thick, with yield strength from 350 MPa to 550 MPa. This high-strength range is what heavy structural applications require.
What are the FX450 line dimensions and weight?
The line measures about 28 m x 3.3 m x 2.4 m and weighs about 35 tons. Plan your workshop layout and floor loading around these numbers, since the FX450 is a full-scale production line, not a compact unit.
How many forming stations does the FX450 have?
24 stations with rollers of 456 mm diameter and shafts of 108/90 mm. The rollers are Cr12 mould steel with quench treatment, sized for the heavy loads of 4.5 mm forming.
What is the power requirement of the FX450?
Two main motors of 18.5 kW each, plus an 11 kW hydraulic unit motor. The dual motor setup provides the forming force for thick gauge work, and voltage is configured to your local standard.
