INSTALLATION OF COMPOSITE ALUMINUM CLADDING

For Aluminum Cladding, supporting angles 50x50x5 Aluminium angle will be fastened to the steel support with M6 nut and bolt.

Continuous Aluminum angle as per the approved drawing will be fixed on to the brackets by using nuts and bolts, so that it forms the sub framework.

Factory fabricated panels will be delivered to site and kept in the safe place.
