Structural Steel Fabrication for Commercial Projects in Michigan
Commercial and industrial construction demands steel that meets precise specifications, tight tolerances, and building code. We have delivered structural steel for Metro Detroit projects since 1999.

Commercial and industrial construction in Michigan requires structural steel that meets precise specifications, tight tolerances, and applicable building code. HotFab Welding has served commercial clients in Warren and Metro Detroit since 1999, delivering structural steel fabrication for warehouses, manufacturing facilities, retail buildouts, and mixed-use construction.
We read and work directly from structural drawings, coordinating with general contractors and engineers so the steel that arrives on your site fits the first time.
What we fabricate
Structural steel work typically involves fabricating beams, columns, lintels, connection plates, and bracing systems from engineering or shop drawings provided by the project engineer. We work from the S-sheets, coordinate with the general contractor, and fabricate components to the tolerances the drawings call for.
We also build steel mezzanine platforms — a cost-effective way to add usable square footage inside an existing building without moving or expanding the footprint.
Working from your drawings
Precision in structural work is non-negotiable. We fabricate to the dimensions and connection details specified, flag conflicts we spot in the drawings before they become field problems, and deliver steel that bolts up cleanly on site. For projects that need it, we provide on-site welding to complete connections in the field.
Commercial and industrial experience
From warehouse racking supports to retail tenant buildouts, we understand the schedule pressure on commercial work. We communicate timelines honestly and treat your project deadline as our own.

What affects the price
Every quote is written after we measure, but the drivers are the same on every job: total length or size, material (steel is most economical, aluminum and stainless cost more), design complexity such as ornamental work or glass infill, finish (powder coating adds cost and years of life), and whether the work is done in our shop or on site. For typical Michigan ranges see our welding & fabrication cost guide.
How to request a quote
Call (248) 259-9956 or send project details through the contact form. Photos and rough dimensions help us quote faster — include the material you prefer (steel, stainless, or aluminum) and a picture of the space or the broken part. We reply within one business day with a free, no-obligation written estimate. Not sure which service fits? See the welding & fabrication FAQ or browse recent work in the project gallery.
Common Questions
Do you fabricate structural steel from engineer shop drawings?
Yes. We work directly from structural (S-sheet) and shop drawings, fabricating beams, columns, lintels, connection plates, and bracing to the specified tolerances, and we coordinate with your general contractor and engineer throughout.
Can you build a steel mezzanine to add space to my building?
Yes. Steel mezzanine platforms are a cost-effective way to add usable square footage inside an existing facility without moving or expanding. We fabricate and install mezzanines to code.
Do you handle commercial and industrial projects?
Yes. HotFab Welding has fabricated structural steel for warehouses, manufacturing facilities, retail buildouts, and mixed-use projects across Metro Detroit since 1999.
