Improved weathertight performance
Being a standing seam roofing system, it does not require piercing or screwing

Assured Leak proofness
Bucket of 425mm width x 53mm deep Valley is huge enough to take care of the highest rain fall and also 360 degree seam will never allow any leakages through side laps

Specially designed roof clip
Floating system for easy thermal expansion and contraction
Low Maintenance
Being a Screw less roof system, major maintenance is not required except in flashing areas

Better walkability & Aesthetics
Profile having cross wise stiffeners at every 150mm which provides better grip and stability while walking on the profile. These stiffeners avoids the Oil Canning effect and provides good aesthetics when Colorbond ® sheets are used

Desired sheet lengths / onsite roll forming
Single sheet from eave to ridge ensuring complete leak proofness

New profile can be offered with 0.5 BMT with max 345 MPa
