The English name of hollow board (also called hollow grid board, Wantong board, corrugated board, double wall board) is: pp plate sheet, which is a light weight (hollow structure), non-toxic, non-polluting, waterproof, shockproof and anti-aging , corrosion-resistant, colorful new materials.
Compared with cardboard structural products, hollow boards have the advantages of moisture resistance and corrosion resistance.
