Common Questions
About sheet metal fabrication.
A quick guide for engineers and procurement teams new to working with a fabrication partner.
What is sheet metal fabrication?
Sheet metal fabrication is the process of turning flat sheet material — typically mild steel or stainless steel — into finished parts and assemblies through cutting, folding, welding and assembly. At Steel Frog, every stage happens in-house at our Bristol workshop, so a drawing or CAD file becomes a finished, ready-to-use component from a single supplier.
How does the fabrication process work?
It starts with your drawing, sketch, DXF or STEP file, which we review for manufacturability. Parts are then laser-cut, CNC-folded on the press brake and, where required, TIG or MIG welded into assemblies. After cleaning and finishing, parts are inspected and delivered — from a one-off prototype to repeatable production runs.
What should I look for in a sheet metal fabrication supplier?
Look for a supplier with all key processes in-house (laser cutting, CNC folding and welding), consistent tolerances across repeat batches, and clear communication at the drawing stage. It's also worth confirming they can scale from prototype to production without changing suppliers — that's how tolerances and quality stay consistent over time.
