The Ralph H. Simpson Company is one of the leading 05500 metal fabrication companies in the Chicagoland area. We serve commercial, residential and industrial developers, builders and owners, as well as the architects and interior designers who work for them. Our product is integrated within new construction in addition to renovation and retrofits. We perform extensive quality checks to ensure that not only are all applicable code and load requirements met—but that our own, stricter standards are met at every step in the process, as well. Our equipment includes half a dozen multi-ton cranes, various grades of welders, plasma cutters, a paint booth, and a five-ton flatbed truck. Many of our assignments involve multiple services for completion of the project, but all our services are available individually.
