Overview

Brownbuilt 900 Performance
 

 

Brownbuilt 900 has been designed with strong ribs that resist buckling under concentrated loads reducing the chance of damage on roofs where foot traffic is common.


Equally useful as a wall cladding, Brownbuilt 900’s aesthetic appeal can be even further enhanced by inverting the profile to create Brownbuilt 900 Reverse Run.
