About Keystone Steel Structures

Keystone Steel Structures specializes in erecting and finishing steel buildings in Pennsylvania, New Jersey, Delaware and Maryland. The owner, Elam King, started the company in October of 2001. The first few years, Keystone Steel Structures 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 general construction services, for entire project. Our services include everything from the initial design and planning stages of a project, to the interior fit outs and final touches, that are  necessary, in order for you to move in and make it yours.


Keystone Steel Structures has built a reputation based on excellent communication and follow through, as well as unrelenting persistence at keeping their promise to supply quality construction on every metal building project.

Regardless of the type of project you have in mind, Keystone Steel Structures has the resources to get the job done.  If you're in need of erection services, supply & erect services, or general construction services for a new metal building, please visit our Contact page or give us a call at 484-722-8274.
