Benefits of a Sandblasted HDU Sign
HDU is a synthetic material that comes in a variety of weights per cubic foot. For sandblasted HDU signs a typical weight would be either a 15 pound or 20 pound HDU. Of course weight affects cost. For most applications, 15 lb. HDU works just fine.
Thickness also has it's place. When a sign is sandblasted some of the material is taken out of the sign so it is important that the sign has a proper thickness for sandblasting. For one-sided signs 1-1/2 inches works well and for double-sided signs, 2 inches would be required.
