Aluminum Posts

Get a durable sign display with commercial-grade aluminum posts available in various sizes. Metal sign posts are extruded with either a light duty .062" or heavy duty .125" thickness and come in round or fluted models. And for rust resistant outdoor performance, aluminum sign posts are sold standard with a black powder coated finish. (For unfinished or alternate colors please call toll free).

When choosing metal sign posts consider local construction code and, in cold climates, the minimum frost line depth. Products featured in this category are constructed for direct-bury applications at a minimum of two feet below grade. To alter aluminum posts for an above-grade surface mount, a supplemental flange is available to purchase separately. Aluminum sign posts measuring above 8-feet high need additional reinforcement for surface mount applications. For large-scale and custom projects, Sign Company Supply also offers custom aluminum post lengths measuring up to 24 feet. Please call toll free for details.
