The traditional method of manufacturing uses very little mechanization and follows the batch production process. Fabrication & assembly is done partly at the factory and partly at the site. The entire process is slow and quality is very much dependent on the worker’s skill at the installation stage. There are a lot of points where quality can be diluted and hence the actual performance is compromised.
The process of Pre Engineered Windows (PEW) is similar to pre-engineered buildings, where the building is designed and fabricated at the factory, and only the assembly of different components is done at the site in a quick burst of speed using nuts or bolts.

Features of PRE ENGINEERED WINDOWS
• The entire window is manufactured at the factory, except assembling and glazing
• The Pre-Engineered window comes in boxes – separate boxes for sash and frame are dispatched
• Logistics and storekeeping become easy as all the boxes are well labeled.
• Manufacturing accuracy is good and there is no mismatch during installation.
• All hardware comes pre-fitted from the factory; site work requires minimum time.
