At O’Mara Ag Equipment in Iowa, custom work isn’t the exception—it’s what we do best. Whether you need a one-off piece of seed processing equipment or a facility-wide structural solution, we bring together engineering expertise, full-scale manufacturing, and a practical, problem-solving mindset to get it done right.
From concept to final assembly, we handle everything under one roof. That means fewer vendors to coordinate, less markup, and faster turnaround times—with consistent custom-built quality from start to finish.
We work closely with seed producers to design and manufacture custom solutions that meet site-specific needs, safety standards, and performance goals. Our AISC-certified facility is fully equipped to handle a wide range of custom fabrication ag projects for seed producers.
We also offer a review of customer-supplied designs, helping optimize for structural performance, installation efficiency, and code compliance.
Control dust at the source. We build custom hoods for nearly any machine or process, with flexible spouting, mounting, and size options. Retrofit or integrate seamlessly into new builds.
From tank and hopper mounts to vibration-reducing equipment platforms, our stands are engineered for strength and stability. Designed for tough ag environments.
Move heavy amounts of seed safely and efficiently. Our rugged towable carts are built to handle awkward loads and constant use. Scaled and outfitted to match your material handling needs.
Safe, durable access solutions built to OSHA standards. Available in exposed rung, caged, bolt-together, or fully welded designs. Optional platforms and tie-ins to existing structures.
We build everything from ergonomic step-ups to complex, multi-access service platforms. Modular or fully welded. Designed to fit your process and your space.
Need to access, cross over, or connect equipment safely? We custom-build structural walkways, mezzanines, and catwalks with minimal components for quick installation. Fully code-compliant and made from high-quality American steel.
