    HDU Signs

    High-Density Urethane (HDU) foam signs offer the look of carved wood at a fraction of the weight and cost. Precision-routed with deep relief and dimensional texture, then painted to any color. Weather-resistant and ideal for monument sign inserts and exterior dimensional signage.
