Here at Stocklin Iron, we have been building steel staircases since 1969, averaging about 400 spiral, custom winding and circular stairs per year for customers throughout the Bay Area and beyond.

We specialize in the design, construction and installation of fully welded steel stairs with no assembly required. No passageway is too small. Feel free to choose from one of our standard models or have us create the staircase of your dreams.

We can help you build anything from a staircase to an iron gate or rail. Everything we do is made to meet the unified building codes. We only use the best materials on our projects.

So feel free to call us or just come by with any questions you have. We would be happy to help you with your next steel project.
