Our Story

AG-CO got its start in the horse stall business in 1976. Since then, the company has evolved from selling horse stalls to manufacturing innovative products for the agricultural and post frame building industries. AG-CO owner Glen George and his team focus on creating lightweight and durable cupolas that are aesthetically pleasing as well. Glen’s experience with metal cupolas fueled his desire to find a better solution. Thirty metal pieces and a box of bandages later, Glen explored his vision of creating a polyethylene alternative. The result is a simple yet stylish, three-piece cupola that comes in many color choices, assembles easily, and remains rust-free. AG-CO Cupolas have been installed all over the U.S. We invite you to view our 'DESIGN' area to create your very own cupola - complete with the weathervane of your choice.
