Benefits of HAVING A METAL AG BUILDING
A metal agricultural building is a reliable, long-lasting solution designed to protect your farm equipment. Here’s why it’s the smart choice:
Must-Have Upgrades for Your building

Rollup Door Header Seal
Upgrade to a heavy-duty vinyl header seal to close the gap above your roller door, providing added protection against dust, drafts, and pests.

Rollup Garage Doors
Upgrade to a manual roll-up garage door for a durable, space-saving solution, ensuring smooth operation, security, and easy access to your building.

1-ft Overhang
Upgrade to an overhang for foundation protection and heavy-duty bracing for added wind resistance, available on vertical roof styles only.

Rat Guard
Upgrade to a rat guard to seal off panels at floor level, preventing rodents and insects while creating a clean, finished look.
Year-Round Protection
Shields equipment, feed, and livestock from harsh weather conditions, ensuring they stay safe and dry.
Low Maintenance
Unlike traditional wood buildings that rot and require annual maintenance, metal is a preferred lifetime choice.
Versatile Layout
Being out on your farm means your office is where your equipment is. All buildings can be customize to fit how you work.
Building permit requirements for agricultural buildings vary based on local regulations, the building's size, and its intended use. In many areas, if the structure is used solely for agricultural purposes on a rural property—such as housing livestock or storing farm equipment—you may be eligible for exemptions or a simplified permit process. However, for larger structures, those with mixed uses, or buildings located in areas with stricter codes, a permit may be required.
It’s important to check with your local building department or zoning office to determine the specific requirements for your project. We’re here to offer guidance and share our experience, but the final decision rests with your local authorities.

The rust on the steel must be throughout the metal and customer must have been correctly maintaining the building.
If there are any issues, please contact the Corporate Office at 309-278-8000. A service order will be issued, and an installer will go to your location to fix the issue. You must provide pictures of the problem areas before our installers head out.

Lead times depend on a few factors. If you have your foundation ready and have acquired any necessary permits from your city and county, the lead time is approximately four weeks. Lead time waiting period starts the moment you approve and sign the quote.

“Building up and done in 2.5 days. Complete walk through done each day…”
“Did a great job. Worked hard. Had their own crew to assemble the building. Obvious they knew what they were doing. Building up and done in 2.5 days. Complete walk through done each day and then a final one. Very smooth process. Very happy with our decision to go with United Metal Buildings. Big shout out to Jaime Cendejas and his crew from Rock Falls Illinois. They travelled 3.5 hours to get to us in Wisconsin, truck trailer and all their supplies. Highly recommend them!”

“Very impressed with the quality of the materials...”
"I have no complaints, only praise. The crew was very efficient and polite. They asked if it was Ok to start at 6:30 AM and if it was OK to leave their trailer parked on my property overnight. I am a retired Foreman and these guys are equal or better than any crew I have ever had. Very impressed with the quality of the materials that were used on the building. Also the crew made sure that the building site was clean and free of debris when they were finished. Very impressed Thank You"
