40x50 Metal building

Our 40′ x 50′ metal building packages are a solid investment. They can be customized to suit almost any end-use application, from a hobby shop to a small inventory warehouse or a modern family home.

With 2,000 square feet of wide-open, clear-span space, you can design a floor plan to suit your intended application. You also benefit from additional overhead space due to the trussless roof design of a rigid frame building.

Engineered using commercial-grade steel I-beams, these structures are designed for the harshest of environments.
