SF Metal Box, Inc. has a story that goes back more than a century. Our roots trace back to 1915, when the business began as Meyers Safety Switch. Over the decades, the company evolved into Meyer Sheet Metal Box, building a reputation for quality craftsmanship, practical expertise, and dependable service throughout the San Francisco Bay Area.

Today, that same foundation lives on through SF Metal Box. We specialize in custom metal fabrication, creating electrical enclosures, data center cabinets, wireway, signal boxes, specialty copper work, and other solutions built around the requirements of each project.

For us, fabrication is more than shaping metal. It's about understanding what the finished product needs to do. We work closely with our customers from the initial requirements through the finished product, combining experience and precision to deliver dependable, purpose-built solutions.

Rooted in the San Francisco Bay Area and built on more than a century of experience, our goal remains simple: build it right, stand behind it, and build relationships that last.
