Abstract

A low amplitude wave-board panel having improved bending strength and bending stiffness properties is provided. More specifically, the amplitude of the waves is substantially equal to, or less than half the thickness of said board. Preferably, the wave amplitude ranges from between 1/8" to about 1".
