Welcome to WeSTco
Strength. Stability. Endurance. You can rely on the power of steel to carry the load. And you can rely on Westco Iron Works to provide the steel for the landmark buildings of the Bay Area. Including yours.

We’re ironworkers. We opened Westco Iron Works in 2005. That makes us the new kid on the block—even though the partners at Westco bring more than 100 years combined experience to the steel fabrication and erection business. Over the last three decades we’ve worked with the biggest construction companies in the Bay Area, fabricating thousands of tons of steel for projects in the millions of dollars. This gives us a solid perspective on new ways to source steel, new production techniques, and new design systems that can reduce construction costs and get the job done right.

Our Services
Before the building goes up, Westco steel goes in. Westco Iron Works fabricates and erects structural steel, miscellaneous metals, stairs, rails, and ornamental metals for large-scale construction projects around the Bay Area.

Our Process
We work hand in hand with contractors to bid out projects that deliver the most value for the best price. We procure materials, order components with long lead times, and create realistic rolling schedules that get the steel to your site as promised. When you build with Westco, you build with confidence.
