Surface Finishing Services for Custom Sheet Metal
Our finishing solutions enhance the durability and aesthetics of your parts. Contact us for specific custom requirements.
As-Machined
Provides a cost-effective option with visible tool marks, as the surface is left directly from the CNC machine.
Anodizing
Improves corrosion and wear resistance while allowing for color dyeing, ideal for aluminum components.
Polishing
Achieves a high-gloss finish, reducing surface roughness and enhancing the aesthetic appeal of the metal.
Sandblasting
Uses pressurized sand or other media to clean and treat the surface, creating a uniform matte finish.
Brushed Finish
Creates a unidirectional fine texture, reducing the visibility of marks and scratches on the surface.
Powder Coating
Provides a thick, durable, and wear-resistant coating with excellent color and texture options for various surfaces.
Electroplating
Bonds a thin metal layer to the part, enhancing wear resistance, corrosion resistance, and surface conductivity.
Black Oxide
A conversion coating for ferrous metals that improves corrosion resistance and minimizes light reflection.
Electropolishing
An electrochemical process that smooths and brightens the surface while significantly improving corrosion resistance.
Alodine
A chromate conversion coating for aluminum that provides corrosion protection and improves paint adhesion.

Sheet Metal Fabrication Design Guidelines
GSG-Tech's sheet metal fabrication design guidelines ensure manufacturability, precision, and cost efficiency. These rules, based on material thickness (MT), help avoid defects like cracking or deformation during bending, punching, and forming.
| Feature | Description (MT = Material Thickness) | Note |
|---|---|---|
| Bend Radii | Recommended inside bend radius starts at 1X MT to prevent material stress and cracking. | Tighter radii may work for softer metals like aluminum but require engineering review for harder alloys. Always specify radius clearly in CAD models. |
| Hole Placement | Maintain at least 2X MT from any hole edge to the sheet edge to ensure structural integrity. | Holes spaced closer than 6X MT center-to-center risk deformation during fabrication. For slots or non-circular features, increase to 4X MT minimum. |
| Bend-to-Feature Clearances | Keep holes or cutouts at least 6X MT from bend lines to avoid tearing during forming. | Add bend radius to this distance if features are on the bend side. Relief notches of 1X MT width help isolate bends from nearby holes. |
| Countersink and Depth Rules | Minimum countersink depth is 0.6X MT to achieve proper taper without breakthrough. | Position countersinks 8X MT from other features to prevent web thinning. Use standard 82° or 90° angles for best tool life. |
| Edge Breaks and Fillets | Apply 0.5X MT fillets at inside corners to reduce stress concentrations and improve flow in bends. | Break sharp edges by 0.01-0.02 inches across all exposed edges to eliminate burrs and handling hazards. Relief cuts should be 1X MT deep for clean separations. |

| Lead Time Stage | Capabilities | Suitable Conditions | Typical Applications |
|---|---|---|---|
| Fast Turnaround (≈3 Days) | Laser cutting, punching, deburring, basic bending (≤10-12 bends), standard tapping and hardware insertion | Thin sheet materials, simple geometries, low complexity parts | Brackets, panels, covers, flat parts, mounting components |
| Standard Production (≈5 Days) | Multi-step forming, tighter tolerances, CNC secondary machining features, more complex bending | Wider material thickness range, moderate complexity designs | Enclosures, functional components, structural sheet metal parts |
| Extended Lead Time (Custom) | Welding, assembly, complex forming, surface finishing (powder coating, plating, marking, masking) | High complexity parts, multi-process requirements, finishing needs | Weldments, assemblies, end-use products, multi-component systems |
