Engineered Commercial Buildings
Pre-Fab Commercial Buildings
Portable Buildings
The pre-engineered metal building system is advantageous because it very economically allows for the creation of large column-free enclosures. The alternative structural framing choices, such as mill steel and light gauge metal, use more steel and are therefore considerably more expensive to build.
