Yard Signs

  • With 4mm coroplast signage, you can create custom yard signs to meet all of your promotional, directional, and political needs (and beyond). Printed in full color on rigid corrugated plastic with optional grommets, they are versatile enough to be placed indoors and durable enough with UV-cured inks and waterproof durability to be staked outdoors. 

    At regular temperatures, oils, solvents, and water have no effect on coroplast which also lends nicely to the endurance of the sign.
