When Stone Creek Coffee Roasters wanted to build a huge coffee cup for the sign at its new Factory Store in Milwaukee, Sign Effectz Inc. was up to the task. Sign Effectz is a custom electrical sign manufacturer in Milwaukee. It works with businesses to translate designs into the final advertising product using a variety of methods and materials. The giant coffee cup, which is seven feet in diameter and four feet and six inches tall, was created by welding an aluminum frame, coating it with foam and then wrapping it in a fiberglass composite, said President Adam Brown.
