Sheet Metal Fabrication Guides
Read sheet metal as a fabrication sequence: select stock, cut the flat pattern, form it, join it and inspect the assembly.

Choose your starting point
Each route below owns a distinct part of the topic. Start with the decision you need to make, then use the focused articles within that route.
Sheet Metal Processes & Supplier Selection
Compare cutting, stamping, welding and supplier capabilities against quantity, geometry and assembly requirements.
Sheet Metal Design, Materials & Assemblies
Plan bend radii, hole clearances, material grade and joints together to prevent tolerance accumulation in the finished assembly.
Before you release the project
- Define the function, environment and the question this batch must answer.
- Specify material grade, geometry, quantity, finish and the dimensions that control fit.
- Agree the inspection method and the evidence required to accept the parts.
- Record the drawing revision and approval before production begins.
Common planning questions
What files are useful for a sheet metal quote?
Supply the 3D model and controlled drawing with material, thickness, quantity, bend and joint requirements, finish and critical assembly dimensions.
Can tight tolerances be applied to every bend?
Bend variation and the assembly datum scheme must be considered together. Focus tighter limits on functional interfaces and agree a measurement plan.
Move from guidance to a reviewed project
Send the CAD model and drawing with material, quantity, finish and inspection requirements. Use the relevant service page to review the available manufacturing route.
