MD Barnmaster is proud to be the innovative leader in modular, pre-engineered barn technology. Our unique construction has revolutionized the horse housing industry since 1975. Let us show you how to “Build A Better Barn” that will stand the test of time. After all, you have enough projects on your to-do list… working on your barn shouldn’t be one of them.

MD Barnmaster’s Laminated Wall System
MD Barnmaster’s laminated wall system is the cornerstone of MD Barnmaster’s basic building design. Our basic 3/4 inch wall consists of high quality 3/4 inch exterior plywood with 26 gauge embossed, high pressure baked enamel coated steel laminated to both sides. The panels are then sealed on the edges to prevent water from “wicking” up the plywood. Our 2 inch wall provides insulation from cold weather climates.

MD Barnmaster’s Proprietary Wall Channel
MD Barnmaster forms its wall channel (framing) from rolled, galvanized 14 gauge steel. The bottom rail of the wall channel is hot dipped galvanized after it is rolled (using the already galvanized material) for superior rust prevention.

MD Barnmaster’s prefab barn kits take the worry out of barn building with barn and building structure kits that are affordable and easy to assemble. American made, our barns and buildings are proudly made at our Ontario California factory with nothing but the best materials sourced domestically and abroad. The walls are smooth without the need for added framing, sheeting and painting.

Our stalls, horse barn kits and prefabricated building kits are delivered to you from the factory completely finished and ready for assembly.

Because almost every component of an MD Barnmaster building bolts together, MD Barnmaster barns can be assembled as “do it yourself” projects or installed professionally at a fraction of the cost of other barns. One-half inch nuts are embedded on the side edges of the completed walls. When assembling the barns, the walls are tilted up and a two inch connector column is positioned vertically along the wall edge. Pre-drilled holes in the connector column line up with the welded nuts on the wall panel and the walls attach to the column with three ½ inch bolts.

MD Barnmaster’s modular design allows you to move your barn or building structure from one property to the next easily and at low cost. MD Barnmaster’s modular design also allows you to add to your barn as your horse housing, livestock, workshop or other needs grow.

Zero Fire Spread Rating
Zero Fire* Spread Rating. Because steel encases the only wood (fuel) used in constructing an MD Barnmaster barn, oxygen cannot reach the fuel. Fire needs both fuel and oxygen. Any fire in your MD Barnmaster barn will burn out without spreading across your barn like it will in a wood structure. Unfortunately, we have all heard of the horrible barn fire disasters that occur in the horse industry. You don’t need to risk having that happen to you and your horses. (*Not available on exposed wood sided products.)

Lifetime Chew-Proof Warranty
Lifetime Chew-Proof Warranty. MD Barnmaster barns have no wood accessible for your horses to chew. We have all seen wood barns and stalls after they’ve had horses in them for a while. What may start out as an attractive wood structure soon ends up as a partially eaten maintenance nightmare. Wood chewing also presents health issues and many believe leads to cribbing, a serious stall vice.

Lifetime Kick-Through Proof Warranty
Lifetime Kick-Through Proof Warranty. MD Barnmaster’s unique wall design prevents horses from kicking through your barn walls, which protects both your barn investment and your horses. Plywood surrounded by steel can withstand any horse kick and we guaranty it for as long as you own your barn. Your horses may dent the walls, but they will not kick through. Imagine the terrible leg and foot injuries this prevents. MD Barnmaster walls also flex slightly when kicked. The entire wall absorbs the shock from the kick, not your horses’ legs.

Won’t Harbor Bacteria – Healthy Horses
Wood barns are almost impossible to keep clean and disinfected. Unless they are finished on the interiors with smooth surfaces, the exposed wood trusses, rough sawn treated posts and other exposed lumber attract birds, pests and dust. Wood harbors harmful bacteria and disease that could endanger your horses’ health. Many surfaces are inaccessible. Even accessible surfaces absorb dirt and bacteria. MD Barnmaster barns are finished with smooth surfaces straight from the factory. Our walls do not harbor harmful bacteria and they can be cleaned with a disinfectant of your choice keeping your horses free from debilitating germs, bacteria, and disease.

No Cuts/Scrapes
MD Barnmaster’s standard proprietary wall channel has no slivers or sharp edges to pull manes and tails or scrape your horses’ hide.

Easy Sanitizing – Low Maintenance
Simply pressure wash your barn as needed to keep them looking new. There are no unreachable spaces to house and conceal spiders and other vermin in your MD Barnmaster building.

Heavy Wind and Snow Load Safe
Our barns are engineered to be the safest and strongest in the market, and out-perform the average barn in handling heavy snow, high winds and jarring earthquakes.

I strongly recommend Coffman Barns. Randy and his crew were consummate professionals from start to finish. He delivers a quality, long lasting product that allows me to focus on my horses instead of repairing my barn. He is extremely honest and actually completed construction ahead of schedule. As my horse business grows, I look forward to working with Randy in the future.

To Randy Coffman, I wanted to say thank you for making my barn building a great experience. You have now built two barns for me and would absolutely use your services again. You are a true professional and would recommend you to anyone looking to build or upgrade their horse facility.  Thank you!

Randy has earned 5 stars from me. He built me a beautiful covered arena a few years ago and an awesome house last year. Then a new barn and another covered arena. I wouldn’t call anyone else. The projects were on budget and on time.


In my experience, Randy Coffman is the person you want to work with if you want your barn built. He is professional, honest, and very detail orientated. Randy does everything he can to get the job done in a timely fashion, and more importantly, correctly.  He knows his profession inside and out and is more than willing to make your barn building experience a pleasant one. I would highly recommend working with him if you want your barn done right.
