Allied Steel Buildings has been the number one provider of pre-engineered steel building solutions and building services in California for over a decade.
California has one of the largest economies in the world, and we are very proud to have helped so many businesses become a success.Our buildings meet California code requirement, have double bolted girts and entryways that are reinforced with joints. Ventilation can get in, but moisture stays out, including summer rain, snow loads, and desert winds. Unlike conventional building materials, steel is designed to move with seismic forces in the event of an earthquake. Our insulated panels meet LEED environmental design, are sustainable, energy-efficient, and cost-effective. Some of our customers include Siskiyou Family YMCA, Van Fleet Trucking, Granada Hill Charter High School, Long Dream Farm, Fain Drilling & Pump Company and many more.
