How fabricated parts are actually made — and where each process earns its keep
Fabrication is a chain of process choices: how the blank is cut, how it is formed, how it is joined, how it is finished. Each link has options with different costs, tolerances and failure modes. This page is the working guide P&A International engineers use when routing parts through our ISO 9000 certified or better partner network.
For the service overview — capabilities, lead times, quality system — see the metal fabrication pillar. This page is the technical layer underneath it.

The fabrication chain
Cutting
Laser, plasma, punch and waterjet — edge quality, heat input and nesting economics differ sharply.
Forming
Folding, rolling and pressing — where K-factors, springback and grain direction live.
Joining
MIG, TIG, spot, rivet, clinch and adhesive — strength, distortion, cost and cosmetics trade off.
Finishing
Powder, paint, plate, anodise and galvanise — corrosion protection chosen for the real environment.
Every process choice below is made for you in our quotes — this page shows the reasoning.
Engineering capability
- Cutting: laser to 25 mm steel, plasma for thick plate, punching for volume, waterjet for heat-sensitive
- Forming: CNC folding with documented allowances, rolling, press forming with tooling
- Welding: qualified MIG/TIG with procedures; spot and stud welding for sheet
- Mechanical joining: riveting, clinching, PEM hardware — when welding distorts or costs too much
- Finishing: powder coat, wet systems, zinc and nickel plate, galvanise, anodise
- Process chains engineered end to end: cut-form-weld-machine-finish in one routing
At a glance
| Cutting choice driver | Thickness, edge quality, heat sensitivity, volume |
| Forming choice driver | Radius, springback, grain, tooling budget |
| Joining choice driver | Strength, distortion, cosmetics, disassembly |
| Finish choice driver | Environment, colour, conductivity, cost |
Why engineers & buyers choose PA
For design engineers
Bad fabrication quotes hide process shortcuts: plasma where laser was needed, MIG where TIG was specified, paint where the environment demanded galvanising. Understanding the chain is how you read quotes — ours and everyone else of them.
For purchasing
Our quotes name the processes, not just the price — so what you compare is what gets built, at partner shops vetted to ISO 9000 or better, with the routing chosen by an engineer who answers for the result.
3 easy steps to get started
Send the part
Drawing plus the loads, environment and volumes.
Routing proposal
The process chain named step by step, with the reasoning and itemised pricing.
Parts with evidence
First articles inspected against the drawing, processes documented in the quality file.
Applications
The same chain logic routes enclosures, frames, guards, brackets, tanks and architectural work — only the chosen links change with thickness, alloy, volume and environment.
Service-level view: metal fabrication in China. Process pages: sheet metal, steel fabrication, stamping and aluminium fabrication.
Common routing calls, honestly made
Patterns from a few thousand quotes:
| Laser vs punch | Punch wins past ~500 parts with repeated features; laser wins flexibility |
| Weld vs rivet | Rivet/clinch when distortion or coating damage costs more than strength buys |
| MIG vs TIG | TIG for cosmetics, thin gauge and aluminium; MIG for speed and thick steel |
| Powder vs galvanise | Galvanise for outdoor structural life; powder for colour and indoor duty |
What to send us for a fast, accurate quote
The more of this you can share, the quicker we can return a proposed process routing and price:
- Drawing or model with material and thickness
- Loads and environment the part must survive
- Cosmetic expectations (visible faces, colour)
- Volumes — they flip several process choices
- Anything that went wrong with previous suppliers
