C/U channel roll forming machine is a CU type purlin roll forming machine used in the production of steel structure industry. The finished product produced by machinery and equipment is CU steel, which is mostly used for the support of beams and wall beams in housing construction and factory buildings. Applicable materials are “strip steel”, galvanized steel coil, etc. The machine has two cutting systems: Pre shear before roll forming and post hydraulic cutting after roll forming part, which meet the needs of different lengths of production. The minimum size is 50-70mm, more used for the functions of solar mounting.

FAQ
What is a C/U channel roll forming machine used for?
It produces CU steel sections used as beam and wall supports in housing construction and factory buildings. It is also used for solar mounting structures, where the small 50-70 mm sections are a common fit for racking profiles.
What purlin sizes can the MC50-250 produce?
C purlins from 50 mm to 250 mm, with quick size change capability. The smallest range, around 50-70 mm, is mainly produced for solar mounting applications.
Why does the MC50-250 have two cutting systems?
It combines a pre-shear before roll forming with a post-hydraulic cutting system after forming. The two systems cover different production length needs, so short and long sections can both be cut accurately.
What coil thickness can the MC50-250 process?
Coil thickness from 1.5 mm to 3.0 mm. Suitable materials include strip steel and galvanized steel coil.
What is the maximum production speed of the MC50-250?
Up to 30 m/min, driven by an 18-station roll forming unit with a 22 kW hydraulic motor.
Can the MC50-250 punch holes and switch profiles?
Yes. The punching system uses 4 cylinders for single or double holes with 3 punch sets, and the PLC controls hole positions. Size changes are done through PLC control or push button, and C/Z interchange works through PLC control with a reverse roller.
