Built upon a solid service-oriented foundation, The Structures Group has earned a far-reaching reputation for operating with efficiency and dependability. We began over 50 years ago as a small California company named, Berkeley Plywood. We used a revolutionary new method for framing a roof on industrial and commercial buildings.

Originally named the Berkeley Panelized System, this framing method became the mainstay for large wood roof structures throughout the West Coast. Today we bring this innovation to projects across the United States. Throughout the years our philosophy has remained steadfast:

Good people, fully motivated and properly rewarded, produce the quality structures and service that our customers respect.
