Curved rails are produced by bending our anodized H-rail.
H-rail is commonly used to suspend complex FabricAir dispersion systems, as there can be bent to suit the elbows. H-rail is produced in 2 meter sections using an extrusion process and then anodized, making it an excellent choice for corrosive environments. Several of the standard suspension methods offered by FabricAir utilize H-rail. When assembling an H-rail system the pieces of H-rail are joined together by using a metal connecter that is fastened to each rail using set screws. The duct will have sliders or a bulb edge to slide into the H-rail at the appropriate locations for both single and double H-rail configurations. The H-rail is suspended using either a cable or metal drop from the structure. H-rail suspension systems use either a single H-rail at the 12 o'clock duct position or two H-rails at 3 and 9 o'clock duct positions.
The rails are bent to the exact angle that is needed to suit the elbows in your FabricAir duct system.
