More than 60 Years of Excellent Customer Service

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 than other shops.


Our Products and Services

As a specialty service shop, we offer a broader range of supplies and services than you’ll find in other shops. Here is a small selection of the things MJB keeps on the shelf:

We stock rebar in lengths up to 60 feet with precut 20-foot lengths always on hand.

MJB Steel always has standard sized stirrups, hoops, dobies and everything you need to properly space and reinforce rebar.

We custom fabricate pier cages, grade beam cages, wire mats and spirals.

On-site hydraulic benders and shears let us fabricate the rebar and steel reinforcement you need.

MJB Steel is also a supplier of TechWay Concrete Dome Tiles by StrongGo. Used to assist those who are visually impaired, these tiles are available in five standard colors, and they can be ordered in a variety of custom colors. TechWay Dome Tiles are durable, fade-resistant and ADA compliant.
