Custom Fabrication


With 12+ licensed professional engineers, 6 designers, and over 28 fabricators, MSS can design, build, and install a wide array of custom prefabricated solutions for your specific application.

Modular Fabrication

In today’s environment, the modularization and prefabrication of systems provides a more cost effective and safer approach for simple or complex projects.  Building these assemblies in a controlled environment offers scheduling benefits, allows for more efficient design reviews, improves overall product quality, and minimizes stacking of trades on the construction site.  With our state-of-the-art equipment and skilled staff, we have the ability to deliver modular fabrication solutions to meet almost any project requirement.
