We Built The Staircase for MTV’s Real World Chicago.

In 1959

Lamonaca Iron Works was one of the first original custom steel fabrication companies in Chicago. Founded by two Italian brothers, who originally perfected their craft by working with International Harvester Tractor & Trailer Company, they have carried on the “Old World” craft with precision and quality to create beautiful and long lasting products for both home and business applications.

From the First Projects

Lamonaca Iron Works has created a style of high-quality, precision iron products, including simple steel handrails for front and back outdoor stairs, as well as steel fences to protect and secure Chicagoland’s houses and commercial properties. This European craftsmanship has yielded the best-made custom spirals and curved metal stairs, unmatched in our industry.

Custom Iron and Steel Works

Lamonaca Iron Works has been privileged to design for such well-known clients as David Bowie’s Business Manager, MTV (Real World), Weather Tech, and The Goodman Theatre, just to name a few. Collectively, these works have given Lamonaca, one of Chicago’s own, a reputation for excellence throughout the country. Let us know what your next project entails and Lamonaca Iron Works will supply the solution.
