Design Flexibility

Custom ORB 935 is a smooth sinusoidal profile which offers flexibility of design for roof and wall cladding application. Wall panels can be installed in horizontal as well as in vertical direction.

Smooth curving

CUSTOM ORB® 990 can be curved smoothly for modern and stylish architectural designs. (For bull nosing use G300 MPa steel).

Minimum Roof Pitch

A special anti-capillary forming in the side lap allows the use of CUSTOM ORB® 990 on roof pitches as low as 5 degrees. Sheet lengths of up to 24 m can be used before an expansion joint is required.

Simple, low-cost fixing
