ST900® PRODUCT TECHNICAL STATEMENT
ST900® is a medium rib profile. Developed for the commercial/industrial roofing and cladding markets, it is equally at home in residential settings where a bolder look is desired. ST900® is distinguished by a subtle swage pan that adds stiffness to the pan, minimising canning and purlin line marking. Lapping ribs are interchangeable male/female, allowing flexibility to the installer, and feature a well-defined anti-capillary detail.
• Durability: All material selections must be compatible with prevailing environmental conditions and adjacent materials.
