Poco was established in 1964 by Murray Powelson. His sons Murray Jr. and Frank joined the family business shortly after. In 1972 the industry expanded and the company grew to include the manufacturing of traffic control products and the installing of permanent signage.

Poco has grown with the industry and now not only install permanent signage, but manufacture the signs in-house. With more than 50 employees we have the knowledge and expertise to handle all of your traffic and signage needs.

Poco will continue to serve Metro Detroit and the state of Michigan in its traffic control and signage needs. We will grow in our service and expertise of special event management.
