A family trade

This is where parts stop being parts and become a product.

Sheet metal has been the family trade since 1979 — Martin started on the shop floor at 14 in his father's business. Bolton Sheetmetal Ltd has carried the craft forward since 2011. Cutting, punching and folding make components. Welding and fabrication is where those components become an enclosure, a frame, a chassis, a finished assembly — the thing the customer actually ordered.

We weld MIG, TIG, spot and handheld laser, across mild steel, stainless and aluminium. Handheld laser welding is the newest of those and the one worth knowing about: it's faster than TIG on stainless and aluminium, puts far less heat into the part so there's less distortion, and leaves a cleaner weld that needs less dressing back — particularly on thin material and visible joints. The right process gets matched to the job, not the other way round.

Full assembly & sub-assembly — the finished component We don't just lay welds. We build the whole thing: cut, folded and welded parts brought together into complete assemblies and sub-assemblies, with hardware inserted where it's needed. The part that leaves is the finished article, not a bag of components for someone else to put together. One business accountable from drawing to despatch.

And it doesn't have to start with us. We weld and assemble free-issue parts as readily as parts we've cut and folded in-house — though when the whole job runs here, there's one tolerance owner and one delivery instead of a chain of suppliers.

The processes

Four ways to join metal. The job decides which.

No single process is best for everything. Running all four means the part gets the right one.

01 / MIG

Speed and strength

The workhorse for production welding and thicker sections. Fast deposition, strong joints, economical on volume. Where the weld is structural rather than cosmetic, MIG usually wins.

ProductionThicker sections

02 / TIG

Precision and finish

The choice when the weld is seen or the material is thin or demanding. Controlled, clean, low spatter — stainless and aluminium work where appearance and integrity both matter.

CleanVisible welds
TIGPrecision & finish
03 / Spot

Fast sheet joining

Resistance spot welding for overlapping sheet — quick, clean, no filler, no distortion to speak of. Ideal for enclosure and panel work where many joints are needed at speed.

04 / Handheld laser

The modern edge

Faster than TIG on stainless and aluminium, with much less heat into the part — so less distortion and a cleaner weld that needs little or no dressing. Particularly strong on thin material and visible joints. Most shops this size don't have it; we do.

The whole line

Where the job finishes — and why that's the point.

Welding is the last operation, and having it here means the whole part was made under one roof.

Cut & punched

Profiles laser cut in-house — mild steel up to 20mm, stainless up to 12mm and aluminium up to 10mm — or punched with holes, forms and taps already in.

Welded & assembled

Brought together, welded with the right process, hardware inserted, finished as a complete assembly — then despatched. One quote, one delivery, one business accountable.

For your quote

What to send for a quote.

The faster and clearer the file, the faster the quote — and the more accurate the price.

  • A 3D model (STEP) of the assembly, or drawings of the parts and how they go together.
  • Weld detail — which joints, weld type if specified, and which welds are visible / cosmetic.
  • Material and finish — and any finishing (powder coat, plating) needed after.
  • Hardware — any inserts, studs or fixings to be fitted as part of the build.
  • Quantity — and whether we're making the parts too or welding free-issue.

File formats accepted

STEP DXF DWG IGES PDF Sketch

A 3D STEP of the assembly is ideal. A general arrangement drawing or even a marked-up sketch of how it fits together is enough to get a quote moving.

Why BSM

There are bigger fabrication shops in the North West.
Here's what BSM brings.

One accountable contact

When you ring us, you get someone who knows your job. No call centres, no account managers shuffling files between sites.

The whole job, one roof

Cut, punched, folded and welded into a finished assembly without leaving the building. One quote, one delivery, one tolerance owner — not a chain of subcontractors.

The family trade since 1979

Sheet metal runs in the family — started in 1979, carried on by Bolton Sheetmetal Ltd since 2011. Family-run. Debt-free. Still here. And working towards ISO 9001 certification.

Honest about fit

We don't offer coded welding. If your job needs formal weld certification we'll tell you straight, before you order — not pretend otherwise to win the work.

FAQ

Welding & fabrication, asked & answered.

What welding processes do you offer?
MIG, TIG, spot and handheld laser welding, across mild steel, stainless and aluminium. The process gets matched to the part — structural, cosmetic, thin, thick — rather than forcing every job through one method.
What is handheld laser welding and why does it matter?
It's a fibre laser welding tool that's faster than TIG on stainless and aluminium, puts much less heat into the part so there's less distortion, and leaves a clean weld that needs little or no dressing back. It's particularly strong on thin material and visible joints. Most shops our size don't run it.
Do you do full assembly, not just welding?
Yes. We build full assemblies and sub-assemblies — cut, folded and welded parts brought together into a finished component, with hardware inserted where needed. What leaves is the finished article, not a kit of parts.
Can you weld parts we supply?
Yes. We weld and assemble free-issue parts as well as parts we've cut and folded ourselves. When the whole job runs here there's one tolerance owner and one delivery, but we're glad to take welding and assembly on its own too.
Are your welders coded or certified?
No — we don't currently offer coded or certified welding. If your work needs formal weld certification, tell us up front and we'll be straight about whether we're the right fit rather than take work we shouldn't.
What's your lead time on welded assemblies?
It depends on the assembly — number of parts, processes and finishing all affect it. Tell us the full job and we'll quote a realistic lead time alongside the price, and tell you before you order if we can't hit what you need.
