Routed Wood-Grain Signs

From a photograph of a wood grain, our router carves out the HDU material
to remarkably resemble a real wood-look.

Our signs look exactly like SANDBLASTED WOOD, but
do not warpdo not split and  do not crack as actual wood signs can.


Simulated Cast Metal Plaques

The elegant look of cast metal is now within reach with our economical Simulated Cast Metal Plaques.
The textured background gives a convincing appearance of sand cast metal
but at a much lower cost.
