Crafted in Steel. Built for Purpose. Made to Last.

There is welding — and then there is fabrication.
Fabrication isn’t just attaching metal to metal.
It’s shaping, fitting, aligning, and refining.
It’s designing a piece that not only works — but works well, reliably, and for the long run.

At 406Weldfab, we operate at that level.

We build, repair, and reinforce steel with intention:

• Clean welds

• Correct tolerances

• Proper load handling

• Strong structure

• Professional finish

Because in Montana, things need to do more than look good —
they need to hold up to real use, weather, weight, and time.

Built for Montana Conditions

Montana is not gentle on equipment.

Temperature swings.
Wind.
Snow load.
Ice.
Weight shifts.
Gravel roads.
Work that needs to get done regardless of the weather.

Our welds and fabrication work are made for that reality:

• Stronger joints

• Correct weld penetration

• Structural reinforcement where it matters

• Rust-resistant finishing options

• Fitment that aligns cleanly and holds its integrity

Durability is not optional here — it’s standard.

Function and Form — Working Together

Steel can be utilitarian.
Steel can also be refined.

We approach each build so that:

• It works the way you need it to

• It looks clean, intentional, and aligned

• Every connection has purpose

• Every weld is done with care

• Nothing feels improvised or temporary

Your project should work and complement the environment it’s built for — whether that’s a ranch shop, a commercial storefront, or a custom home.

Straightforward Process

1. Tell us what it needs to do
   (Function comes first.)

2. We design or sketch the solution
   Clear, direct, practical.

3. Fabrication + welding
   Precision, alignment, structural integrity.

4. Installation or pickup
   Done correctly — the first time.

No overcomplication.
No unnecessary steps.
No cutting corners.

Our Work is Our Reputation

Every weld has our name on it.
Every project reflects our standards.
Every client matters.

That’s why builders and homeowners across Helena call us when they need metal work done right — not just done.
