MDO Signboard — Classic Strength Meets Lasting Performance
When you need a dependable, professional-grade sign material that can handle the elements, MDO (Medium Density Overlay) — also known as Signboard — is a proven favorite. Made from exterior-grade plywood topped with a smooth, resin-saturated paper face, MDO offers the perfect balance of traditional durability and clean, paint-ready performance.
This high-quality overlay provides a smooth, uniform surface that resists warping, moisture, and cracking — ideal for outdoor business signs, real estate panels, construction site boards, and more. With its waterproof core and weather-resistant surface, MDO stands up beautifully to rain, sun, and seasonal changes, while maintaining a professional look that lasts.
