Trapezoidal Profile

The trapezoidal shape provides greater water carrying capacity and provides greater spanning capabilities than corrugate (sinusoidal) profile. For nomenclature or description of the parts of the sheeting used in this COP, see Product Geometry.

The maximum available fastener density (fastener per square metre) on deep trapezoidal cladding profiles is usually lower than on corrugate, because of the wider rib spacing and longer spanning capability of stronger profiles. 

Trapezoidal profiles are available with different ribs heights (see Profile Types).
