Keystone Steel Structures is a small company that specializes in erecting and finishing steel buildings. The owner, Elam King, started the company in October 2001. The first few years Keystone was only involved in the erection of the steel structure itself. However, due to customer demand, we have chosen to expand the company’s services to include supplying a complete pre engineered metal building package as well as concrete work and interior fit-outs for the entire projects. View our photo gallery to see a few of the projects we have undertaken. Keystone Steel Structures has built their reputation with excellent communication and unrelenting persistence at keeping their promises to supply quality construction.
