Coroplast is extrused from the product line with melting polypropylene with polyethylene raw material together with high temperature. It’s also called hollow grid plate as the lattice shape for the corrss-section.
Coroplast is short for corrugated plastic. These sign pieces can be used as so-called "Sandwich Board Signs". The fluting in the coroplast runs vertically so that wireframes can be used to place your sign horizontally.
