DB Series

Modular permanent Coverall buildings

DB Series features a curved roof profile, characteristic of a coverall building. It’s remarkably strong and distributes weight evenly, making it a stable and efficient format with no hard angles or corners, enclosing an enormous amount of space without any interior load-bearing columns. This arch-shaped structure also excels at shedding rain and snow.

All DB Series profiles, epitomizing the coverall building design, meet or exceed site-specific design criteria, offering narrow to wide spans with no center load-bearing columns.

Each structure is fully engineered specifically for your site location and is available with a structural engineer’s seal. The arch-style design comes in many different profiles to fit your needs, and custom designs are available. DB coverall buildings offer exceptional value.
