Automatic Sizes Adjusted C & Z Shape Purlin Roll Forming
Machine With Gimbal Gear Box Driving System
This metal roll forming machine is designed to produce galvanised
steel C & Z Profile Purlins with different sizes. If holes are
required on the finished C & Z purlin sheets, we will install
punching devices at the beginning of the roll forming machine.

Componets Descriptions of Metal Cee and Zee Purline Roll Forming
The maximum capacity of the coil decoiler can hold is 3 tons. It is
designed for the coils with 508mm
inner-diameter and maximum 1000mm outer-diameter.
It adopts wheel and screw which are used to regulate the iron stick
for direction guilding.
This leveling device adopts 7 rollers (3 rollers up and 4 rollers
down) to make the steel sheet flatly into the
The main frame of machine is welded separately and the outside wall
is connected by screws after being
painted on the surface. The rollers are made by Cr12 mould steel of
high quality, which are processed
with quenching treatment. The rolling shafts are made by No.45
carbon wrought steel of high quality, which
can improve the integrated mechanic feature of the rolling shafts,
then the rolling shafts will be processed
by cylindrical grinding machine to ensure the precision of final
Holes Punching Device:
The holes punching dies are made by Cr12 mould steel to get a good
hardness and lifespan.
Cutter blade is made by Cr12 mould steel with heating treatment.
The cutter’s structure adopts welded
frame for good rigidity. The power of cutting action is provided by
Supporting Tables for Finished Products:
They are used to support the finished products. It is convenient
for the workers to stack the finished products.
Hydraulic Station for Cutting Device:
The motor and hydraulic accessories are with famous Chinese brand
which guarantee the hydraulic station is
supplying stable the power for the step presser and cutter.
PLC Control Cabinet:
The control system adopts Mitsubishi PLC, inverter, touching screen
for all the working actions of the machine.
Some parameters, such as product quantity, product length and so on
can be set into the PLC controller, then
this machine will automatically produce the desired products
according to the set parameters.
Tools Box with Spare Parts:
The tools box contains the necessary tools such as spanners,
screwdrivers, pilers, oil pot and useful spare
parts such as control buttons, position switches, mini relays,
chains and so on.
In steel construction, purlins are typically used as roof framing
members that span parallel to the building eave, and support the
roof decking or sheeting. The purlins are in turn supported by
rafters or walls. Purlins are most commonly used in Metal Building
Systems, where Z-shapes are utilized in a manner that allows
flexural continuity between spans.
