Our Sheet Metal Fabrication Services

Laser cutting

Laser Cutting

  • Max length 3m
  • Max thickness 30mm
  • Various material available

Laser cutting is a fast method to get sheet metal part off from the sheet with a custom shape by laser.For simple sheet-designed part, it is very convenient and fast with good price while it always regards as the basis of sheet metal fabrication process.

Bending

Bending

  • Max thickness 20mm
  • Support complex structure
  • Min length for folded edge 5.5mm

Bending is normally used for forming a specific shape, generally for enclosure or structure. The cut sheet by laser cutting process will be bent according to the designed angle feature by customer. U-shape and V-shape are almost the most popular bending features.

Welding

Welding

  • Thin gage welding
  • Custom fixture for welding
  • More economical & fast than other joint processes

Industrial designers always consider using welding process in their sheet metal project to join two sheets together and enhance the strength. Welding is widely used for complex structures which can not be formed by simply laser cutting or bending.

Riveting

Riveting

  • Solution for complex networks of materials
  • Strong connection option
  • Join dissimilar materials

Riveting is a method of connecting parts using axial force to thicken and form nail heads in the rivet holes of the parts to achieve the purpose of connecting multiple parts without any other components.

Our sheet metal factory was established in 2015. There were initially had more than 50 engineers with more than 20 years of experience specializing in sheet metal fabrication area. With the development of nearly 10 years, we gradually built a professional sheet metal processing team to support the whole project development cycle, from concept to prototype and mass production. We supported more than 1000 companies on their sheet metal project. Meanwhile, we are also available for ODM service with our R&D team. Turnkey is proud and honored to help hundreds of startup companies with design & manufacture service and grow with them at the beginning. Come and let us bring your sheet metal project to life together.

Available Sheet Metal Finish in Turnkey

sheet-metal-sample

Standard (Default)

If you do not require any finish, we will delivery as showed while it is also our standard options. For safely handling, shape edges are deburred before ship part out.

Brushing

Brushing

For better appearance, brushing is a nice option with regular trace and competitve cost.

Turnkey Sheet Metal Sample 6

Anodizing

Only avaiable for aluminum sheet metal parts, form a stable oxidation layer to protect the sheet better is daily use.

Turnkey Sheet Metal Sample 3

Electroplating

A thin metallic protective coating is applied to the surface of the part, which will help the part to achieve a more wear-resistant, shiny, and corrosion-resistant surface.

Turnkey Sheet Metal Sample 8

Powder Coating

Widely used for parts require nice appearance or high resistance, the layer is thicker than painting or anodizing.

Turnkey Sheet Metal Sample 5

Painting

The painting layer is noramlly 15~20μm, and not stable as powder coating, May flake off during daily use.

Tolerance for Sheet Metal Fabrication

In order to guarantee the accuracy of the parts and to maintain consistent quality, we generally default to dimensional tolerances for sheet metal parts in accordance with the ISO2768-M standard. If you want your project with different tolerance, please kindly inform us when quoting.

Our Customers Say About Us

Turnkey is really awesome. I had a sheet metal project and need it in very short time, Turnkey supported and every feature was just as I designed - Jonas Martins Industrial Engineer
- Industrial Engineer
Never expect to get parts with so nice appearance. I wanted the sheet to be glossy Ral painted. They really made it very shiny and nice.
cnc customer feedback
- Global Supply Chain Manager
It was a large sheet welded project, Turnkey made very stable protection for shipment, I got it in perfectly condition, and I can not appreciate any more. -Sarah P. Automation Purchaser
