Steel Fabrication

TMI Contractors was built on our steel fabrication expertise. While we have grown to be a multi-craft provider, steel fabrication will always be at the heart of what we do.

Our Steel Fabrication Capabilities

As custom metal fabricators, we combine innovative technology with expert processes and finishing services to offer you a complete solution. Our facility in Mount Vernon, Indiana, can fabricate parts in-house to help maximize your budget, including assembly of platforms with grating and handrail, stair stringers, or trusses.


We will work with you, your budget, and your unique needs to manage logistics— we’ll ship steel all over North America and overseas. We even run our own hot-shot truck and trailer for loads less than 18,000 lbs to simplify regional shipping.
