The manufacturing plant has been molding expanded polystyrene (EPS) blocks and custom molded parts for more than 20 years. The entire manufacturing process is controlled from beginning to end, expanding and molding the EPS used in our signs.
The EPS core material gives the sign its shape and structure. Starting with the best material possible ensures the best, finished products. The quality of EPS that goes into our signs is closely monitored, without relying on outside suppliers. Our EPS conforms to ASTM C578-08 specifications.
In years past, some fabricators sold a sub-standard sign that was not designed for exterior environments manufactured from High-Density Urethane.
Our Monument Plus signs are made from a composite of expanded polystyrene (EPS) and a structural polyurea hard coat. Our signs are not made of high-density urethane (HDU).
