Purlin Roll Forming Machine
Purlin Roll Forming Machine
Steel purlins are necessary for pre engineered steel industrial buildings, and some residential building as well, and various kinds of c/z purlin roll forming machines have been
developed to produce C/Z/U steel purlins, Sigma/M purlins sometimes are also available.
In accordance with different requests for C and Z steel purlins, we have specified C purlin roll forming machines for production of C steel sectional channels, Z purin roll
forming machines for manufacturing of Z shaped channels and interchangeable C/Z purlin roll forming machines which are designed to produce both C and Z steel purlins
without replacing any rolling tools or cutting dies.
They are mostly galvanized or cold rolled steel strips from feeding, punching for holes, bending and cutting. Some customized requirement would also be acquired, such as
high speed is flying shear and non stop holes punch with servo motor drive. Heavy gauge purlin could be upto 5mm thickness, with gear drive transmission; Sigma profile,
Omega profile, U section could also be made by the same machine. Some more special requests are coming on the way.
The whole purlin roll forming machine line is including decoiler, holes punching device, roll forming machine, hydraulic power pack, hydraulic shear, electric controller and run
out table; motorized decoiler with hydraulic expansion, also coil car is optional; Bomb type auto stacker is also available.
Types of Purlin Roll Forming Machine
• C Purlin Roll Forming Machine
Structure of C Purlin Roll Forming Machine
C Purlin machine consists of 3 tons manually decoiler, straighten rollers, holes punching device, forming rollers,
hydraulic cutting device, PLC controller and stacker.
Working Process of C Purlin Roll Forming Machine
Coiler loading → feeding-in with guiding (metal sheet is guided into the first forming station) → straighten → rolling &
forming → holes punching →hydraulic cutting → stacker running out
Z Purlin Roll Forming Machine
CZU Purlin Roll Forming Machine
High Speed Z Purlin Machine
High Speed Lip Channel Machine
Heavy Gauge (Heavy Duty) Purlin Roll Forming Machine
Cold-formed steel Purlins / Girts are structural steel members for framing, both roof and wall, widely used in steel construction. They are in turn supported by walls or rafters, mostly
C shapes or Z shapes are used. In the steel industry, structural steel is commonly used as channel sections, with or without flange stiffeners, both C shape and U shape are usually
referred. They're shaped on a bending press, to create a web with two flanges. They could be a variety of sizes. Multiple holes punching is for any installation requirement. In steel
building construction area, roof and wall are frequently cold formed steel sections. Steel framing is an important component of pre-engineered steel buildings. Purlins provide
additional support for the roof. They make horizontal support for the weight of roof deck. They also help make entire roof structure more rigid. Because they add mid-span support,
purlins allow longer spans, enabling to create a wider building.
Because of development of structural steel industry, roll-formed steel profiles are used as more and more applications, not only for infrastructure, industrial and commercial segments
but also for solar mounting systems. C purlins and Z purlins, also U purlins could be made for building solar racks, with any required holes for installation.
Applications of C and Z Shaped Section Channels:
Since the moment of inertia on Z purlin's weak axis is much bigger than that of C purlin, Z purlin works much better from the integrity point of view.
Z steel purlins can be overlapped continuously while C steel purlins cannot, therefore, it's better to use Z steel purlins instead of c purlins on metal buildings with continuous spans.
Z purlins are much stronger than C purlins due to its continuous or overlapping capability. In this case, for the metal building with bigger roofing loading capacity.
On the roofing of steel framed structures with single spans, and for supporting walls, it's better to use Cee purlins because it's easy to install and calculate. They can work as the
support for the roof, walls, and floor etc.
For the metal buildings installed with concealed fixing or klip lock roof panels, Z purlins can work better than C purlins.
Since all the purlin machines could be customized built, profiles sizes could be C profile, Z profile, U profile, Omega profile and Sigma profile, with various sizes, holes punching could
be made according to real requirement, pre-punch and post punch are both available, pre-cut and post shear are both optional, even flying shear and non stop punch with servo
motor drive is available when high production capacity is needed. Other machine specifications, such as running speed, transmission drive type, plain run out the table or auto stacker
(bomb type) could be chosen. It depends on production capacity and budget. Decoiler is also a necessary part of the whole production line for steel coil processing, manual one?
Hydraulic expansion? Motorized rotation? The hydraulic expansion is reducing labor cost and time to fasten steel coil after coil loading into the decoiler; Motorized rotation mostly is
being used for high-speed production, because it will feed steel sheet automatically into the roll forming machine.
