Our sheet metal fabrication capabilities

Our network of manufacturing partners gives you easy access to sheet metal fabrication capabilities to serve all your manufacturing needs.

Laser cutting
Laser cutting

This manufacturing process uses a high-power laser beam to cut a material sheet.

  • Allowable sheet thickness: 1-6mm (depending on material)

Bending process
Bending

This manufacturing process uses dies to produce a U-shape, V-shape or channel shape along a straight axis in ductile materials.

  • Allowable sheet thickness: 1-6 mm (depending on material)

Sheet metal fabrication materials

Here is a list of our standard available metals for sheet metal fabrication. If you require a custom material please contact networksales@protolabs.com.

Aluminum 5052, 5754
Stainless steel 304, 316L
Mild steel 1018
Copper C110

Tolerances for sheet metal fabrication

The table below summarizes the standard tolerances of the parts produced by our certified manufacturing partners.

Feature Tolerance
Cutting feature ± .00787’’ (0.2mm)
Bend angle ± 1.0°
Bend to edge ± 0.010” (0.254mm)

Available surface finishes for sheet metal

Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts.

Standard sheet metal surface finish
Standard

This is our standard finish. Parts as delivered as cut and bent, no additional treatment applied. Sharp edges are broken and deburred for safe handling.

Bead blasted surface finish for sheet metal
Bead blasted

Parts are bead blasted with glass beads which results in a grainy texture. Sharp edges are broken and deburred for safe handling.

Brushe sheet metal surface finish
Brushed

Parts are manually brushed with grit #180 after cutting and bending. Sharp edges are broken and deburred for safe handling. Ideal to reduce the surface roughness of a part.

Brushed + anodized type II sheet metal surface finish
Brused + Anodized type II

Parts are dipped in an anodizing bath (type II) after manual brushing. Ideal for increasing the corrosion resistance of the part. Ideal for increasing the corrosion resistance of the part. Sharp edges are broken and deburred for safe handling.

Bead blasted + anodized type II sheet metal surface finish
Bead blasted + Anodized type II

Parts are dipped in an anodizing bath (type II) after bead blasting. Ideal for increasing the corrosion resistance of the part. Sharp edges are broken and deburred for safe handling.

Anodized type III sheet metal surface finish
Anodized type III (Hardcoat)

Parts dipped in an anodizing (type III) bath directly after fabrication. Ideal to improve corrosion and wear resistance of components. Sharp edges are broken and deburred for safe handling.

Powder coated sheet metal surface finish
Powder coated

Powder coating layer is applied directly after fabrication. Sharp edges are broken and deburred for safe handling.

Black oxide sheet metal surface finish
Black oxide

Parts are dipped in a black oxide bath after fabrication. Ideal to improve improve corrosion resistance and minimize light reflection in steel components. Sharp edges are broken and deburred for safe handling.

Chromate conversion coating sheet metal surface finish
Chromate conversion coating

Parts are dipped in an alodine bath directly after fabrication. Ideal to increase the corrosion resistance of the part while maintaining its conductive properties. RoHS compliant. Sharp edges are broken and deburred for safe handling.
