Below is a list of Aluminum Frames manufacturers from Pittsburgh, Pennsylvania. Aluminum frames are components of modular framing systems that are constructed out of many different units. The separate frames are attached by bolts or studs to serve as structural systems for commercial, industrial and architectural construction. Aluminum is a great alternative to wood, as it does not warp or rot and has high temperature resistance. It is also a great alternative to steel that is often utilized in construction because of its light weight.
