    Why Coroplast

    Built to Survive the Elements

    Corrugated polypropylene delivers unmatched value for outdoor signage — waterproof, UV-resistant, and economical.

    UV-Cured Inks

    Our UV-cured printing process bonds ink directly to the coroplast surface, resulting in vibrant colors that resist fading from direct sunlight exposure.

    Waterproof

    Polypropylene plastic is naturally waterproof. Rain, sprinklers, humidity — nothing penetrates or warps your sign. Oils and solvents have no effect either.

    Wind Resistant

    The corrugated flute structure provides surprising rigidity for its lightweight. 10mm coroplast handles high winds that would bend thinner materials.

    Fast Turnaround

    Same business day production available. Standard orders ship next business day. We handle single signs and bulk orders of 200+ with equal speed.

    Product Specs

    1
    4mm White CoroplastStandard4mm rigid corrugated polypropylene. Full-color UV-cured printing. Single (4/0) or double-sided (4/4). Waterproof.
    2
    10mm White CoroplastPremium10mm rigid corrugated polypropylene — 6mm thicker than standard. UV-cured printing. Single or double-sided. Extra durable for harsh conditions.

    H-stake note: When ordering H-stakes, place your sign order with width larger than height and select vertical flutes. H-stakes slide into vertical channels.

    Flute note: The corrugated flute structure creates a very subtle linear effect (faint lines) on the surface. This is a natural characteristic of all coroplast and is generally not noticeable at normal viewing distances.
