The SX10 automatic C/Z purlin roll forming machine represents a historical breakthrough in high-speed, stepless roll forming technology. It is the industry’s first interchangeable purlin machine featuring an advanced post-cutting system that eliminates the need for blade changes, enabling ultra-fast, seamless shearing.
Powered by our independently developed Stepless Changeover System, this machinery is widely utilized across high-end cold roll forming lines, including C&Z and standard C purlin production.

FAQ
What is the stepless changeover system on the SX10?
It is Metoform’s independently developed system that adjusts the C/Z profile size continuously and automatically, without stopping the line. The adjustment works down to the millimeter, so both standard and non-standard purlin sizes can be produced on the same machine.
How does the post-punching system on the SX10 work?
The SX10 punches holes on the already formed purlin. The PLC controls the punch quantity and horizontal position, the vertical position is adjusted manually, and the punching sizes can be changed to suit different hole patterns.
Does the SX10 need to stop the line when changing purlin sizes?
No. The stepless changeover adjusts the size while the line keeps running, and the post-cutting system cuts both C and Z profiles with the same blades, so there is no downtime for tooling changes.
What is the de-coiler capacity of the SX10?
The mechanical de-coiler handles coils up to 6.0 tons. The feeding and leveling device flattens the material before it enters the roll forming system.
What steel grades and thicknesses does the SX10 accept?
The SX10 processes cold rolled, hot rolled, and galvanized coil from 1.0 mm to 3.0 mm thick, with yield strengths Q195 and Q235.
Is the SX10 only for C and Z purlins?
No. Beyond C and Z purlin production, the machine is widely used on high-end cold roll forming lines that run standard C purlins as well, which makes it a flexible choice for mixed production.
What drives the roll forming system on the SX10?
A three-phase asynchronous main motor drives about 18 groups of forming rollers through a single chain drive. The rollers are Cr12 mould steel machined on full CNC equipment, and the shafts are ground twice for precision.
