About Us

Bay Area Spiral Stair specializes in designing and building high-quality custom steel spiral staircases for homeowners, contractors, and designers throughout the Bay Area. Every spiral stair is custom-built to your exact specifications, with precise on-site measurements taken by our team once your project is ready. From fabrication to finishing, we fully build each spiral staircase in-house, offering durable powder coating with or without zinc primer, as well as painted or galvanized options for both interior and exterior use.

After fabrication and finishing are complete, we schedule professional installation—typically completed in about five hours for a standard residential spiral staircase. From start to finish, you can enjoy a seamless process and a custom spiral stair designed to enhance your space, improve access, and add long-lasting value to your home or property.
