Sheet Metal Fabrication

JDL Innovations offers complete sheet metal fabrication from our Jimboomba workshop, servicing Brisbane, the Gold Coast, Logan, and customers across Australia. Our capabilities include laser cutting on a 3kW fibre laser (3000 x 1500mm bed), CNC bending on a 135-tonne press brake with 2.5m bending length, TIG and MIG welding, hardware insertion, and assembly. We handle material thicknesses up to 6mm for most bending operations, with bending accuracy of ±0.5 degrees. From a single bent bracket to a full production run of welded enclosures, we manage the entire process in-house. This means fewer handoffs, faster turnaround, and tighter control over quality at every stage.

We fabricate in mild steel, 304 and 316 stainless steel, and aluminium alloys including 5005, 5052, 5083, and 6061. Each material has distinct bending and welding characteristics. Mild steel is the most economical choice and welds easily. Stainless steel offers corrosion resistance for food-grade, marine, and chemical environments. Aluminium is lightweight and suits applications where weight savings matter, but requires careful bend allowance calculations due to its tendency to crack on tight radii. Our team can advise on the best material for your application. See our material guides at jdlinnovations.au/materials for detailed grade comparisons and mechanical properties.

Good sheet metal design starts with understanding bend allowances, minimum flange lengths, and relief cuts. We recommend maintaining a minimum inside bend radius equal to the material thickness, and keeping holes and cutouts at least one material thickness away from bend lines to prevent distortion. Uniform thickness across your part simplifies manufacturing and reduces cost. If you are designing sheet metal parts for the first time, our blog post on how to design for sheet metal at jdlinnovations.au/blog/how-to-design-for-sheet-metal covers the fundamentals. For a deeper understanding of flat pattern calculations, read our guide on the sheet metal K-factor at jdlinnovations.au/blog/sheet-metal-k-factor-explained. These resources will help you produce parts that are easier and cheaper to manufacture.

For flat laser-cut parts, upload your DXF file to our instant quoting tool at jdlinnovations.au/instant-quote and receive pricing in seconds. For parts with bends, upload a STEP or 3MF 3D model and our system will automatically detect thickness, bend lines, and cut paths to generate an accurate quote including bending costs. For more complex fabricated assemblies — welded enclosures, multi-part assemblies, or parts requiring hardware insertion — contact us at jdlinnovations.au/contact with your drawings and we will provide a detailed quote. We handle everything from single prototypes to production quantities with no minimum order.
