  Z PURLINS
 
 

Z Purlins are most unique cold roll formed section used to fix roof and side claddings. The advantage of using Z purlins is unlimited depth and thickness option which gives the designer the required freedom to design most economical purlin.

The higher Zxx value gives more stability in lateral direction and thus maximizes saving.
Designer can select different thickness Z purlins with similar depth for the same structure, which ensures overall economy for the structure. Sleeved Purlin system ensures continuity and rigidty to the structure.
With the use of properly designed Z purlins, one can save upto 40% of steel to be used in construction as compared to conventional system of using Hot rolled purlin or Hot rolled angles or tubes.
With additional attachment we can do concealed wiring for services which improves aesthetic value of the structure. If proper planning is done, provision can be made for hanging tightfitting from Z purlins.

 
 
  CEE PURLINS (LIPPED CHANNELS)
 
 

'CEE' Purlins can be used in place of Z purlins or conventional hot rolled C Channel or IS angles or tubes for fixing roof or side cladding.
This new time saving bridging system with a comprehensive range of accesories available provides a complete, easily erected system. This system provides effiecient light weight, economical roofing and cladding supports for framed structures.
Cee Purlins are supplied readyfor erection and once erected, requires minimal maintainance throughout the life of the building.
