Welcome to Specified Systems, Inc.

Established in 1992, Specified Systems, Inc. has grown to become one of the region’s most prolific erecting distributors of architectural aluminum windows, aluminum storefront and doors, low-rise aluminum curtain wall, and specialty glazings. Based in Canonsburg PA, the company covers a large geographical area which extends north to Erie PA, south to Clarksburg WV, east to Harrisburg PA, and west to Columbus OH. We have become known for our specialization in institutional and commercial product applications.

Specified Systems is an erecting distributor. We are not commissioned sales agents, brokers, or wholesalers. We work closely with architects, general contractors, building owners, and physical plant departments to specify the right product for the required application. We do our own field engineering and sizing, generate our own shop drawings on CADD, write our own engineered orders for manufacturing, manage our own installations, and service our own work.
