Structural Steel Fabrication
HPS Fabrications builds structural steel and custom weldments in carbon steel, stainless, aluminum and alloys. Assembly happens on fixture tables we designed and built ourselves, in a bay roughly 100 feet long under a gantry crane. If it is large, welded and has to carry load, this is the page for it.

| Scope | Structural steel fabrication, custom weldments, assemblies |
|---|---|
| Materials | Carbon steel, stainless steel, aluminum, alloys |
| Fixturing | Fixture tables designed and built in house |
| Assembly space | Roughly 100 feet of bay length under a gantry crane |
| Forming | Press brake and shear |
| Machining | Bridgeport mill, drill press, tubing notcher |
| Welding | Certified welders and fabricators, retested on a regular schedule |
Large, welded, and load-bearing
This is the core of what HPS does. Cutting and forming feed it; finishing follows it.
The work ranges from a single custom weldment to equipment built in segments because it is too large to move in one piece. The molten salt bath systems, over 100 feet long and 20 feet on each side: was built that way over three and a half to four months.
Fixtures decide whether it fits together
A weldment is only as accurate as the fixture it was built in. We design and build our own fixture tables, which means the fixturing suits the part rather than the part being forced onto whatever fixturing exists.
For repeat production that also means the tenth assembly matches the first.
Fabricators, not just welders
Tom D’Angelo draws the distinction sharply:
A welder lays down a bead and joins two pieces of metal. A fabricator reads a print, works out how the assembly goes together, and builds it. We hire fabricators.
On a large weldment that difference is the difference between a part that assembles and one that has to be cut apart and redone. Our welders and fabricators are certified across carbon steel, stainless and aluminum, and retested on a regular schedule.
Welds are inspected in process, not only at the end, see quality and compliance.
Working with our engineers
If the structure does not exist yet, or an existing one is not performing, our licensed professional engineers can analyse and design it before anything is cut: wind loads, structural weights and loads, finite element analysis.
That is the design-build route, and it is the reason customers bring us problems rather than only prints.
Finished, not just fabricated
Structural work leaves here coated. Our paint booth is at our second Michigan facility, so the assembly never leaves our control to be painted by somebody else.
What to send
Drawings if you have them, STEP or DWG preferred. If you do not, send the load, the envelope, the environment and any standards it has to meet.
Common questions
Structural Steel Fabrication: questions buyers ask
Do you need finished shop drawings?
No. If you have a full drawing package we will build to print. If you only know what the structure has to carry and where it has to fit, our licensed professional engineers will do the design as part of the job. Wind loads, structural weights and loads are work we do in house.
What size of structure can you build?
The main bay is roughly 100 feet long under a gantry crane. Equipment larger than that is built in segments and engineered to align when assembled on site, which is how we delivered a salt bath system over 100 feet long and 20 feet on each side.
Are your welders certified?
Yes. Certified welders and fabricators, retested on a regular schedule, across carbon steel, stainless and aluminum. All incoming material is inspected and weld inspection happens in process.
Do you install, or only fabricate?
Both. HPS covers the full lifecycle: concept, design, fabrication, assembly and installation, with field support. That is the point of buying from one company rather than four.
Can you handle fit-up problems on site?
Yes, and it is one of the reasons to buy design and fabrication from the same building. When field dimensions do not match the drawings, the engineers who designed the part are down the hall from the fabricators who built it.
