Description

FORMFLOW® C90™ corners are the seamless corner solution for LYSAGHT CUSTOM ORB® clad buildings when combined in the LYSAGHT CUSTOMFLOW™ solution.

With a bend geometry perfectly matched to CUSTOM ORB® corrugated cladding, FORMFLOW® C90™ corners provide a structurally independent, no-gaps solution to the challenges of joining corrugated sheets end to end at building corners and other junctions.

In addition to delivering an elegant finished look, FORMFLOW® C90™ corners may also help deliver energy efficiency, maintenance, safety and installation benefits and can also improve fire resistance capabilities of a structure in some applications.
