C-Z Purlin Roll Forming Machine

Cold Roll forming Machines for production the steel Structural frame products - C and Z purline in Building construction industry

The leading suppliers for the C Z purline changeable roll forming line in this metal processing machinery industry. C & Z automatic changeable purline roll forming machine is used to roll form C and Z purlines for PET buildings construction. This is the source from our agent patent design in New Zealand. It is no need to replace any parts or change the spacer position on the roll form line for production of C purlin to Z purlin, only need to rotate side roll forming tooling to get the C and Z purline production. The profile width can be adjusted by hand wheel or power control. It is optional. This C Z purline forming machine adopts the duplex width adjustable technology.

C-Z purline changeable roll forming machine components
The whole roll form line is consisted of de-coiler, material feeding entrance, flatting device, holes punching equipments, main roll forming machine, hydraulic cutting part, hydraulic system, PLC control system and run out table, etc.

C Purline & Z Purline application

C and ZPurlin is an integral part of light steel structure, Purlins and Girts are roll-formed from Hi-Tensile Galvanised steel.
With the advantage of Cee & Zee purlin, widely adopted in Building construction Industry – commercial and residential, they are primarily used to provide lightweight, economical, efficient roofing and cladding support systems for framed structures.
C PURLIN SECTIONS: C sections have flanges which are equal in size and are commonly used for simple supported spans. C sections cannot be lapped continuous spans in multi-bay buildings, but easily adapted for use in small and medium sized buildings as structural framework.
Z PURLIN SECTIONS: Z sections are made with one flange broader than the other. When one purlin is rotated 1800 two sections can be bolted together enabling them to be lapped. Lapping the purlins over interior supports improves the load capacity and rigidity of the purlins. Z sections may also be used for simple spans. Purlins and Girts that are lapped form a structurally continuous line along the length of the building
