High-Precision Sheet Metal Fabrication Manufacturer
Sheet metal is a flat sheet of metal with varying thicknesses. The sheet metal fabrication process involves machining these raw sheets into functional parts. RFS provides comprehensive sheet metal fabrication services, including laser cutting, stamping, bending, welding, and finishing. We follow strict regulatory and industry standards from initial material selection to precision machining to final surface treatment. Regarding raw materials, we can also work with various metals, including steel, aluminum, brass, and stainless steel. We always follow high-quality standards to provide every customer with custom sheet metal fabrication solutions.
We have different sheet metal processing equipment, including CNC bending machines, hydraulic presses, welding robots, and laser cutting machines. These equipment can meet different customized sheet metal processing needs. Our factory also has a team of experienced engineers who are professionals in sheet metal fabrication manufacturing.

Get a QuoteHow Does the Sheet Metal Fabrication Process Work?
Sheet metal processing is the process of processing flat metal sheets into finished parts or products. This process typically begins in the design and engineering phase. At this stage, we use CAD drawings to determine the shape, size, and tolerance requirements of the parts. Next, the raw material is cut to the specified dimensions using methods such as laser cutting, punching, or shearing.
After cutting, we will perform basic processing on the metal sheet, such as bending, rolling, or stamping. For some more complex designs, we may need to perform multiple bending operations. If the product requires assembly, it undergoes welding, machining, and surface treatments (such as coating or polishing). Finally, we inspect each component and assemble them into the final product.
When performing this type of processing, RFS pays close attention to the connection between each step. For example, the accuracy of the cutting directly affects subsequent bending and assembly. Therefore, the initial work is not too rough. In steps such as bending and welding, the dimensions are kept within a relatively stable range to avoid later adjustments. Overall, the focus is not on making any one process particularly outstanding, but on making the entire processing flow smooth. This results in a more stable finished product.
Tolerances for RFS Sheet Metal Fabrication Services
If you don’t specify tolerance requirements, RFS will follow the ISO 2768-mK general tolerance standard in our sheet metal fabrication process. This allows for consistent performance and quality of all parts when specific tolerances are not specified in the drawings. “MK” classification provides a balanced dimensional and geometric accuracy level for most industrial applications. RFS can also provide customized tolerances for specific projects. You can let us know in advance if you have special tolerance requirements.
Linear Dimensions – ISO 2768-1 (Class “m”)
| Nominal Size Range (mm) | Tolerance (± mm) |
|---|---|
| up to 3 | ±0.1 |
| over 3 to 6 | ±0.1 |
| over 6 to 30 | ±0.2 |
| over 30 to 120 | ±0.3 |
| over 120 to 400 | ±0.5 |
| over 400 to 1000 | ±0.8 |
| over 1000 to 2000 | ±1.2 |
Angular Dimensions – ISO 2768-1 (Class “m”)
| Nominal Range | Tolerance (± degrees) |
|---|---|
| All ranges | ±1° |
Geometrical Tolerances – ISO 2768-2 (Class “K”)
| Feature Type | Tolerance for Length (L) ≤ 10 mm | 10 mm < L ≤ 30 mm | 30 mm < L ≤ 100 mm | 100 mm < L ≤ 300 mm |
|---|---|---|---|---|
| Straightness/Flatness | 0.05 mm | 0.1 mm | 0.2 mm | 0.3 mm |
| Perpendicularity | 0.2 mm | 0.3 mm | 0.4 mm | 0.5 mm |
| Symmetry/Positional | 0.1 mm | 0.2 mm | 0.3 mm | 0.5 mm |
L = length of the feature being toleranced
Note: These tolerances apply only when no specific tolerance is indicated on the drawing.

RFS Sheet Metal Surface Finishes
Powder Coating
RFS offers powder coating, which gives sheet metal parts a stronger and more uniform surface. In addition, it also makes sheet metal parts less prone to scratches and rust.
Galvanizing
If the part is to be used in a wet environment, we can coat it with zinc. This prevents the parts from rusting.
Anodizing
RFS can anodize aluminum parts. Anodizing makes the part’s surface less susceptible to corrosion and allows the surface to take on color.
Electroplating
We use electroplating to coat parts with a thin metal layer like nickel or chromium. It improves both the appearance and durability of the product.
Painting
RFS also offers traditional spray painting. In addition to adding color to the surface of a part, spray painting also protects the surface of the part.
