HDU routed signs are available at Elite Letters & Logos in different thicknesses. As your wholesale sign manufacturer we offer different thicknesses between ½” and 2” thick.  HDU stands for High Density Urethane and is extremely durable, yet lightweight. HDU carved signs are strong and hold up extremely well in any weather condition. Unlike typical wood signs, these custom signs will not warp, crack, or bow under outdoor exposure. They can be routed with a flat or wood grain texture background and painted to match your clients’ signage needs.
