Services — fitter general, fabrication and welding

01 · Service line

Fitter general

Mechanical fitting, assembly and alignment — the work that turns delivered steel and machinery into something that runs true and stays where it was put.

Most of our fitting work is on live sites: plants that shut down on a Friday night and have to be back in production on Monday morning. That shapes how we work — the scope is measured and agreed before the shutdown window opens, consumables and spares are on site before the crew is, and the dimensional check is done before the crane is released, not after.

On site

Structural steel erection, bolt-up and torque to spec
Machine set-out, levelling and shimming to drawing
Conveyor, gearbox and drive alignment
Pipework spool fit-up, flange alignment and bolt tensioning
Access platform, stair and handrail installation

In the plant

Shutdown and breakdown fitting on agreed windows
Strip, inspect, replace and rebuild of mechanical assemblies
Bearing, coupling and seal replacement
Guard, chute and liner replacement
Dimensional check and as-built mark-up at handover

Typical fitting scopes and how long they run
Scope	What it involves	Typical window
Plant shutdown fitting	Pre-agreed strip and replace list, crews working shifts against a fixed window	48–96 hrs
Conveyor install	Gantry set-out, drive alignment, belt tracking and guard fit	1–2 weeks
Steel erection	Off-load, set-out, plumb, bolt-up, torque and sign-off	2–9 weeks
Breakdown call-out	Assess, make safe, temporary repair or replace	Same day

Tolerance

Fabricated assemblies are set out and checked to ±1.5 mm over a 6 m run unless the drawing calls for tighter. Where the drawing calls for tighter, we say so at quotation stage rather than discovering it on site.

Fabrication

Custom steel from drawing to finished structure — cut, formed, drilled, assembled and welded in the shop, or built up on site where the piece is too large to transport.

We fabricate to your drawing, or we produce the shop drawing ourselves from a site survey and get it signed off before cutting. Every job carries a material take-off so you can see what steel is being bought against what is being built, and off-cuts stay on your account rather than ours.

Welding

Structural and pipe welding by coded welders, with the process chosen for the joint, the material and the position — not for whichever machine happens to be plugged in.

Procedures are matched to the drawing before work starts, welders are qualified for the position and process they are put on, and every weld is visually inspected against the procedure before dispatch. Where a job calls for third-party NDT — dye penetrant, magnetic particle, ultrasonic or radiography — we coordinate it and hand the reports over with the job.

Processes we run
Process	Material	Typical range	Where we use it
MIG / GMAW	Mild steel, stainless, aluminium	1.0–12 mm	Shop fabrication, long runs, plate work
TIG / GTAW	Stainless, aluminium, thin-wall pipe	0.8–6 mm	Root passes, food-grade and visible welds
Stick / SMAW	Mild steel, low alloy	3–25 mm	Site work, wind, positional and heavy sections
FCAW	Mild steel	6–25 mm	Heavy structural, out-of-position site welds

Welding scopes

Structural steel welding to drawing
Carbon and stainless pipe welding
Plate, hopper and chute seam welding
Build-up and hardfacing on worn components
On-site crack repair and plating

Quality control

Welder qualification records issued with the quote
Procedure agreed against the drawing before starting
Fit-up and root gap checked before welding out
100% visual inspection before dispatch
Third-party NDT coordinated where specified

Non-conformance

A weld that does not meet the procedure gets cut out and re-run. It does not get dressed over, filled or signed off on the promise that it will hold. That rule costs us hours occasionally; it has never cost a client a failure in service.

04 · Scope

Materials we work in

Most work is mild steel. Stainless and aluminium are routine; exotic alloys we will tell you honestly when they are outside our procedures.

Material, form and finish
Material	Typical forms	Finish options
Mild steel	Angle, channel, IPE/UB sections, RHS/SHS, flat bar, plate	Primer, two-pack, hot-dip galvanising
Stainless 304 / 316	Sheet, plate, tube, pipe, flat bar	Dressed and pickled, brushed, passivated
Aluminium	Sheet, plate, extrusion, tube	Mill finish, dressed, powder coat
Galvanised steel	Sheet, section, pre-galvanised tube	Zinc-rich touch-up at cut and weld points
Pipe — carbon	Sch. 40 and Sch. 80, socket and butt weld fittings	Primer, wrap, or as specified

Material is bought against the take-off for your job and marked to it. Mill certificates are passed on where the supplier issues them and where the specification calls for traceability.

06 · Working with us

How we quote

A firm price inside 48 hours of having enough information to price it — and a plain statement of what is included, what is excluded and what we have assumed.

What we need, and what you get back
Stage	From you	From us
Enquiry	Drawing, sketch or measurements; site and dates	Acknowledgement same working day
Survey	Site access and a contact who knows the plant	Measured survey, photos, marked-up sheet
Quotation	Confirmation of scope and finish	Firm price, material take-off, lead time, exclusions
Award	Written order or signed quotation	Programme, method statement, welder records

What to send

A photo of the existing installation, a rough sketch with dimensions, the material and finish if you know it, the site, and the date it has to be in service. That is enough to price most jobs without a survey. Send it here.
