When your project demands strength, speed, and scalability, a pre-engineered metal building is the solution. O’Neil’s PEMB structures combine precision-engineered steel systems with efficient construction methods to deliver durable, cost-effective buildings tailored to your specifications. Ideal for warehouses, industrial facilities, retail spaces, or agricultural applications, these buildings offer wide clear spans, flexible interior layouts, and minimal maintenance for decades of reliable performance.

Our warehouses are designed to maximize usable space, improve efficiency, and minimize overhead. From clear-span layouts to customizable door placements and insulation options, we build storage and distribution facilities that scale with your business.
Every detail matters in a production environment — from layout and ventilation to access and durability. O’Neil industrial buildings are engineered for workflow, safety, and long-term strength. Whether you’re housing heavy machinery or managing production lines, our post-frame and hybrid steel systems offer the flexibility you need with the resilience you expect.
For large-scale farming or equestrian operations, we design versatile barns and storage structures that protect equipment, livestock, and feed from the elements. Our buildings are designed for ventilation, space efficiency, and easy access — ensuring daily operations run smoothly in every season.
