What is Sheet Metal Fabrication?
Sheet metal fabrication involves transforming flat steel or aluminum sheets into structures or products through precision cutting, punching, folding, and assembly. The metal can be shaped into virtually any form, primarily through cutting and thermal processes. Specialized tools like band saws and torches ensure precise cutting, while press brakes facilitate the creation of sharp bends and angles. Welding techniques such as staggered welding and fixture usage prevent distortions during assembly. Defects can be rectified using oxy-acetylene torches. The final product is sandblasted, primed, and painted to ensure optimal aesthetics before delivery to the client.Please contact us for project inquiries or further details.Get Instan Quote
Our Sheet Metal Fabrication Capabilities
The forming process bends or deforms the material into the required shape. This technique differs from cutting, which involves the removal of material, as forming manipulates the material's geometry without altering its mass.

Sheet Metal Tolerances
"Precision Perfected: Embrace the Power of CNC Machining Tolerance for Immaculate Precision in Every Dimension."We follow ISO 2768 standards for Sheet Metal Fabrication Parts.
| Limits for nominal size | Plastics (ISO 2768- m) | Metals (ISO 2768- f) |
|---|---|---|
| 0.5mm* to 3mm | +0.1mm | +0.05mm |
| Over 3mm to 6mm | +0.1mm | +0.05mm |
| Over 6mm to 30mm | +0.2mm | +0.1mm |
| Over 30mm to 120mm | +0.3mm | +015mm |
| Over 120mm to 400mm | +0.5mm | +0.2mm |
| Over 400mm to 1000mm | +0.8mm | +0.3mm |
| Over 1000mm to 2000mm | +1.2mm | +0.5mm |
| Over 2000mm to 4000mm | +2mm | +0.5mm |
Sheet Fabrication Design Guideline
| Feature | Description |
|---|---|
| Inner corner fillets | Design the inner corner rounding to be 0.020 " - 0.050" larger than the standard drilling diameter. Follow the ratio of drilling diameter to depth 1:6 (1:4 recommended) as a guideline for the radius of the inside corner radii. |
| Undercuts | Always design undercuts to standard sizes and away from corners to allow for cutting tools. |
| Tapped/threaded hole depth | Provide tool clearance slightly beyond the depth of the tapped hole to ensure a complete thread. |
| General tolerance | Tolerances on metals wil be held to +/- 0.005*(+/- 0.127 mm) inaccordance with 1SO 2768 unless otherwise specified. Plasticsand composites will be +/- 0.010”. |
| Threading | We currently support UNC and UNF threads from #2 up to 0.5 in., and metric threads from M2 to M12. Avoid modeling internal threads on your part design. |
| Complexity | Keep the number of small cuts to a minimum to reduce CNC machining costs; only design in the necessary features to balance function with aesthetic. |
