Custom Coroplast signs are lightweight corrugated plastic boards for yard signs, fence signs, real estate promotions, elections, graduations, and temporary event signage. Full-color direct UV printing is available on one or both sides of 4mm white Coroplast. Coroplast Sign Specifications Material: 4mm white corrugated plastic with internal channels called flutes. Print: single-sided or double-sided, full-color direct UV printing. Finish: UV ink with a matte finish. Custom size: up to 48 inches x 96 inches. Finishing: optional grommets; wire H-stakes are available for compatible sign configurations. Coroplast is suited to indoor and temporary outdoor signage. It is a fluted board, not a smooth solid PVC panel. Confirm the mounting, exposure, and display duration for your project before ordering. H-Stakes, Grommets, And Flute Direction Wire H-stakes fit into the open flute channels, so flute direction matters. Signs with a width over 48 inches have horizontal flutes. For a staked sign, confirm the size and orientation with us before ordering. H-stakes and grommets are optional, not included with every Coroplast order.
