Protop Inc has been involved in many New Construction projects, as well as construction rehabs. As such, on its turn, when the framing process is arriving, the Protop Team executes it with high efficiency. We have done numerous of framing jobs, some of them were wood framing and some of them metal framing. In the city of Chicago, any residential project that is not higher than four stories, wood framing is the requirement. Over four stories building, and commercial, metal framing is the requirement. For Protop, it doesn’t really makes the difference with which material we’re working with, we masters with both wood framing and metal framing.
