Some parts of Northern California experience heavy snow during the winter, but SteelMaster’s prefabricated arches are the perfect solution for areas that experience heavy snowstorms. Our snow-rated buildings are some of the strongest in the industry.

Over a third of the country’s vegetables and two-thirds of the country’s fruits are grown in California. Northern California’s wetter climate and rich soils create the perfect conditions for growing crops.

Our steel agricultural buildings are some of the strongest structures in the industry. Every SteelMaster Quonset Hut is constructed with high quality, commercial-grade steel that is corrugated at our factory to further enhance the strength of the building. We offer a wide range of customizable metal prefab barns and storage buildings that come in different models and sizes. Not only do we offer prefabricated kits, but we can also customize a structure to fit your needs and budget.

One of the biggest benefits of owning a Quonset hut storage building is the 100 percent usable space. Every SteelMaster building is self-supporting, which means they do not require the use of beams and trusses to stand. Our agricultural building kits have been used to store large tractors and other equipment, hay storage, sand storage, grain storage and much more.

Barn builders in Northern California should have no trouble assembling a SteelMaster building. An average steel farm building can be put together with a small crew in just a few days. Our buildings only require the use of one size nut and bolt.
