Key Features
-
Fully Automatic Size Changing via PLC: No manual roller adjustments or spacer changes are needed. The web size (80-350mm) and flange parameters are fully automated and easily adjusted through the smart PLC touchscreen.
-
Fast 5-Minute C/Z Interchange: Transitioning between C and Z profiles takes only 3 steps and under 5 minutes, drastically reducing downtime compared to traditional roll formers.
-
Linear Guide-Way Assembly: Equipped with premium linear guide ways, the machine ensures smoother, faster, and highly precise web size shifting.
-
Heavy-Duty Gearbox Drive System: Unlike chain drives, our independent gearbox drive provides superior torque, exceptional stability, and uniform forming force for heavy-duty 3.5mm materials.
-
Flawless Final Product Quality: Advanced roll tooling ensures high-precision profiles with zero flared ends (no open mouth), excellent straightness, and uniform shapes.
-
High Yield Strength Capacity: Robustly engineered to process standard cold-rolled, hot-rolled, and galvanized steel coils with yield strengths up to 550Mpa.

FAQ
What materials and thicknesses can the FX350 process?
The FX350 processes cold-rolled, hot-rolled, and galvanized steel from 1.0 to 3.5 mm, with yield strength from 350 to 550 MPa.
What C and Z purlin sizes can the FX350 produce?
The FX350 supports automatic web size adjustment from 80 to 350 mm, with flange parameters adjusted through the PLC control system.
How does the C-to-Z profile changeover work?
The FX350 uses a fast C/Z interchangeable system. Switching between C and Z profiles takes about 5 minutes in three steps, while size adjustment is controlled automatically by PLC.
What is the production speed of the FX350?
The roll forming speed reaches 30 m/min, with a typical production speed of 12–18 m/min, depending on the number of punching operations.
Why does the FX350 use a gearbox drive?
The independent gearbox drive provides stable torque and uniform forming force, making the machine suitable for heavy-duty steel up to 3.5 mm thick.
Does the FX350 include automatic punching and cutting?
Yes. The production line integrates hydraulic pre-punching, pre-shearing, roll forming, and hydraulic post-cutting. Cutting blades do not need to be replaced when purlin sizes change.

Applications
Commercial Infrastructure & Logistics Hubs
For logistics hubs, e-commerce fulfillment centers, and commercial complexes, the FX350 delivers highly uniform C/Z channels. The high-precision profiles ensure superior straightness and zero flared ends, guaranteeing seamless nesting (overlapping) and fast, bolt-ready installation for complex steel structures.
Solar Ground Mounting Systems
The FX350 is an ideal choice for manufacturing heavy-duty solar brackets, posts, and structural rails. It easily processes high-tensile galvanized steel up to 3.5mm, producing rigid solar components engineered to withstand severe outdoor environments, high wind loads, and heavy snow velocity.
Mezzanine Framing & Agricultural Buildings
The rigid profiles are widely used as high-capacity floor joists in industrial mezzanine systems to support heavy machinery and warehouse racking. Additionally, they provide the reliable structural durability required for agricultural facilities, including livestock sheds, grain storage, and large-scale greenhouses.
