Detroit Sign-A-Rama Says: HDU signs are a great alternative to wood!

HDU (high-density urathane foam) signs are the newer, better version of the three dimensional or routed wooden signs of yesterday. Unlike wood that can rot and warp, HDU stands the test of time as a weatherproof/climate proof material that requires no upkeep. Because a stable base means a longer-lasting finish, paint looks new for years longer. HDU is stronger than wood, yet lighter and can still be hand-carved or sandblasted to achieve a wide variety of looks at an affordable price.
