Custom Metal Fabricationbuilt to fit.
When the part you need doesn't exist off the shelf, we build it.

Custom metal fabrication in the Treasure Valley
When off-the-shelf doesn't fit.
Plenty of jobs start with the same problem: the part you need isn't sold anywhere, or the one that is doesn't quite fit. A mount that's an inch off. A rack that has to clear something specific. A bracket for a machine nobody makes parts for anymore. That's where custom fabrication comes in — instead of forcing a stock piece to work, we build the exact thing for the exact spot.
Idaho Welding Service handles one-off metal work across the Treasure Valley for homeowners, contractors, farmers, and shops. Brackets, mounts, frames, racks, bumpers, skids, steps, guards, and equipment modifications — welding and fabrication built around how the piece gets used, not around what happened to be on a shelf.
Start with a sketch, a photo, or the broken part
You don't need drawings. A phone photo, a napkin sketch, or a few measurements is usually enough to get started. Call or text what you've got and you'll get a straight answer on whether it's buildable, what material makes sense, and roughly what it runs — before anything gets cut.
What we build
One-off metal work, made to do a job.
Custom fabrication covers a wide range, but it almost always comes down to the same thing — a piece of metal cut, fit, welded, and finished to do something specific. If you can describe how it needs to work, it's usually something we can build.
- Custom brackets, mounts, and plates to hold, attach, or adapt gear
- Frames, racks, skids, and stands built to size
- Bumpers, steps, guards, and hitches for trucks and trailers
- Equipment modifications and add-ons for the way you work
- Repair-by-fabrication when a part is obsolete or backordered
- Steel, stainless, or aluminum — matched to the job
Where custom work shows up
Built for the shop and the driveway.
Work & equipment builds
Working gear rarely comes set up exactly how you need it. Attachment mounts, weld-on brackets, guards, skid frames, tool racks, and modifications that make a machine do more than it shipped with — that's daily fabrication. When a part finally quits and it's obsolete, we can measure the old one and build a replacement so the equipment keeps earning instead of sitting.
Home & property builds
Around the house and property it's the same idea at a different scale. Trailer racks and toolboxes, gate hardware, fire pits, shelving and stands, mounts for a hitch carrier, a bracket to hang something heavy the right way. Tell us what it holds and how it gets used, and we'll build a piece that fits the space and takes the load.
Metal fabrication and welding services, start to finish
How a weld-and-fab shop works.
From design to a finished part
Every build walks the same path, whether it's a single bracket or a full frame. It starts with the concept — what the piece has to do and where it has to fit. From there we measure the real space, not a catalog spec, then cut and fit the metal so the joints line up before a single weld is laid. Only once it fits do we weld it solid, then finish it — grind the welds, knock down sharp edges, and prep or coat it so it holds up outside. That handoff from design to a finished part is the whole point of custom steel fabrication: you get a piece made for your job instead of a stock part forced to work.
Lighter jobs lean on sheet metal work — panels, covers, guards, and boxes cut and bent to shape — while heavier builds call for thicker plate and structural stock. Either way, the sequence holds: figure it out first, cut and fit carefully, then weld. Getting the fit right up front is what keeps a build square and strong instead of something patched together after the fact.
The right metal, and repair before replace
Most work is mild steel — it's strong, it welds clean, and it's the sensible choice for frames, mounts, and equipment builds. Stainless goes where a piece needs to shrug off rust or stay food-clean, and aluminum earns its place where weight is the enemy, like a rack you have to lift or a part on something that moves. Matching the metal to the job matters as much as the welding itself, so we talk through how the piece gets used before settling on material.
Not every problem needs a brand-new build, either. When a part cracks or wears out, it's often faster and cheaper to repair it than to fabricate a replacement from scratch — and we'll tell you straight which way makes sense. If the old part is obsolete or backordered, that's when fabrication earns its keep: measure what's left, build a piece that fits, and keep the equipment working. Repair when repair holds, replace when it won't.

How a custom build works
From a rough idea to a finished piece.
Custom fabrication doesn't have to be complicated. Most builds follow the same simple path — you show us what you need, we tell you straight whether it's buildable and what it runs, then we cut, fit, weld, and finish it. No drawings required to get started.
1. Photos or a sketch
Text a photo of the part, a rough sketch, or a few measurements. Even a description of what it needs to do is enough to get the conversation going.

Common questions
Custom fabrication FAQ.
What kinds of custom metal fabrication do you build?
One-off builds and modifications — brackets, mounts, frames, racks, bumpers, skids, steps, guards, and equipment mods. If it needs to be cut, fit, welded, and finished in metal, it's the kind of thing we build. Tell us how you'll use it and we build to that.
How much does a custom fabrication project cost?
It depends on the build — the material, the size, how much fitting and welding is involved, and how it needs to be finished. The fastest way to get a real number is to text photos, a sketch, or measurements to 208-409-0756. You get a straight answer before any work starts.
Can you build from a sketch or a photo?
Yes. A napkin sketch, a phone photo of what broke, or a few measurements is usually enough to start. Full drawings are welcome but not required — a lot of custom work starts with a rough idea and gets figured out together before anything is cut.
What metals do you work with?
Mild steel for most structural and equipment work, stainless where it needs to resist rust or stay clean, and aluminum where weight matters. We'll talk through which material fits the job and how you'll use it so the build holds up in the real world.
Can you fabricate a replacement part that's no longer made?
Often, yes. When a part is obsolete or the replacement is backordered, we can measure the old one — or what's left of it — and fabricate a piece that fits and works. Repair-by-fabrication keeps older equipment running when parts just aren't available anymore.
Do you build on-site or in a shop?
Both. Modifications and repairs to equipment that can't move are handled on-site with mobile welding. Standalone builds — racks, frames, brackets, and the like — are usually built where the tools are and delivered ready to use.
Got something to build?
Calling is fastest. You can also text a sketch, a photo of the part, or measurements, along with where you are in the Treasure Valley, and we'll get back to you with the next step.
