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.
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
CUSTOM ORB® 990 can be fixed with hex head screws, which is fast and simple. The standard overlap is one and a half corrugations. Wider profile makes it easier to cover large area in shortest possible time.
Improved Thermal Performance
CUSTOM ORB® 990 profile comes with THERMATECH™ Solar Reflectance Technology that lowers surface temperature by absorbing lesser heat from the sun. It keeps both roofs & buildings cooler at reduced energy costs.
CUSTOM ORB® 990 is manufactured from Al-Zn alloy coated COLORBOND® and ZINCALUME® steel that offers excellent corrosion resistance and lasts up-to four times more than ordinary Zinc coated steel profiles.
