The YX18-76-836/988 (arc) is a specialized wavy-profile corrugated sheet designed for high structural efficiency. It features a standard rib height of 18mm and a pitch of 76mm, creating a classic “arc” or sinusoidal shape that excels at shedding water and resisting wind loads. This model is particularly valued in industrial construction for its high moment of inertia, allowing for longer spans between supports compared to flatter profiles.
