This San Francisco location first opened its doors in 1947. MJB Steel took ownership in 1980, and over the years, we have maintained high quality and customer service standards. We serve customers throughout the commercial, industrial, and residential sectors, and we guarantee that whether you buy one or 1,000 bars, you will receive the same fast and friendly service. Not only can we fabricate rebar and steel reinforcement to your needs, but we also carry a large selection of products and accessories that most other fabricators don’t stock. Stop in and you’ll be able to find things like dobies, tie wires, mesh, hoops and stirrups in stock so that you won’t need to order your parts and supplies ahead. Ready availability of parts and supplies plus fast fabrication of custom reinforcements lets us take care of our customers much more quickly
