Sheet Metal Fabrication: a buyer's sourcing guide
Everything a procurement team should know before opening an RFQ for sheet metal fabrication: materials, tolerances, certifications and red flags.
Recent RFQs in sheet metal fabrication
Overview
Sheet metal fabrication combines laser/punch cutting, press bending and welding to build enclosures, frames, brackets and panels. It is the backbone of most industrial enclosures and machinery covers.
When to choose this process
Use it for panel parts and structural sheet assemblies from 0.5 to ~10 mm in steel, stainless or aluminium.
Typical materials
- DC01/S235 mild steel
- AISI 304/316 stainless
- Aluminium 5754/6082
- Galvanised steel
- Corten
Typical tolerances
Cut ±0.1 mm, bend ±0.2 mm / 0.5°, welded assembly ±1 mm/m.
Certifications to ask for
- ISO 9001
- EN 1090 (structural)
- EN ISO 3834 (welding)
Frequently asked questions
DXF or STEP for sheet metal?
Both: a flat DXF for nesting plus a 3D STEP for bend simulation. Mark bend radii, grain direction and welds explicitly.
Can the same shop cut + bend + weld + paint?
Most mid-size shops handle cut, bend and TIG/MIG welding in-house; powder coating and zinc plating are typically subcontracted within their network.
