Off the shelf finishes
There are various sheet metal surface finishes that are available off the shelf, including brushed and treated variants.
Raw
Visible tooling marks and light surface scratches.
Raw Copper C101
Visible tooling marks and light surface scratches, oil coated to prevent corrosion.
Stainless Steel (304/316) 2B
Smooth mill finished, cold rolled and moderately reflective.
Stainless Steel (304/316) 2N
Smooth mill finished, cold rolled and slightly more reflective than 2B finish.
Galvanised
Appears with a rough pattern, high level of corrosion resistance.
Stainless Steel (304/316) 4N
Brushed one side with 150-180 grit grain in one direction.
Type II sulphuric anodising
Type 2 sulphuric anodising is usually done to protect the surface or apply a coloured dye to improve aesthetic appeal. Anodised colours can be matched closely to specific Pantone or RAL colours when using our colour tolerance guide. Standard thickness ranges are typically between 5µm to 25µm.
Blue
Provides increased corrosion resistance and improves aesthetic appearance.
Clear
Provides increased corrosion resistance and improves aesthetic appearance.
Silver
Provides increased corrosion resistance and improves aesthetic appearance.
Bronze
Provides increased corrosion resistance and improves aesthetic appearance.
Black
Provides increased corrosion resistance and improves aesthetic appearance.
Gold
Provides increased corrosion resistance and improves aesthetic appearance.
Green
Provides increased corrosion resistance and improves aesthetic appearance.
Yellow
Provides increased corrosion resistance and improves aesthetic appearance.
Purple
Provides increased corrosion resistance and improves aesthetic appearance.
Orange
Provides increased corrosion resistance and improves aesthetic appearance.
More colours available including colour matching
Provides increased corrosion resistance and improves aesthetic appearance.
Powder coating
Powder coating is a common finish for sheet metal components due to the continuous and even coating that protects the base material from corrosion as well as improves the aesthetic appearance. All exact match Pantone and RAL colours are available with Powder Coating. Standard thickness ranges are typically between 50µm to 70µm.
RAL 9005 Black (Matte 30%±5%))
A grainy matte appearance that does not reflect much light.
RAL 9005 Black (Satin (60%±5%))
A smooth surface with slightly reflective appearance.
RAL 9005 Black (Gloss (70%±5%))
A smooth surface with highly reflective appearance.
RAL 9005 Black (High Gloss (80%±5%))
A smooth surface with very highly reflective appearance.
RAL 7004 Grey (Gloss (70%±5%))
A smooth surface with highly reflective appearance.
RAL 9010 White (Gloss (70%±5%))
A smooth surface with highly reflective appearance.
RAL 3001 Red (Gloss (70%±5%))
A smooth surface with highly reflective appearance.
All RAL colours available including colour matching
A smooth surface with highly reflective appearance.
Mechanical
Mechanical finishes are typically for improving aesthetics or preparing a base material for an additional treatment.
Bead Blast
Grainy, slightly matte texture that removes tool marks and light scratches
Mirror Polishing
Hand polished to create high cosmetic mirror-like appearance.
Vibratory Polished
A great way to de-burr and smooth the surface of parts leaving feint grainy lines.
Brushed
A single directional heavy grain is mechanically applied to the material.
Tumbling
A great way to de-burr and lightly polish the surface of parts.
Chemical
Chemical finishes are used to treat components in bulk, as they are relatively cost effective and cover all surfaces of a component.
Electropolishing
Shiny and smooth surface that also enhances corrosion resistance.
Satin Finish
Grainy, slightly matte texture that removes very light marks and scratches.
Chemically brightened
A reflective and shiny surface that is often used to prepare parts before anodising.
Iridite NCP
Excellent corrosion resistance, adhesion promotion and non-toxic.
Passivating
Excellent corrosion resistance by removing impurities to increase durability.
Chemical Blackening (Black Oxide Coating)
Applies a thin and uniform black finish that prevents corrosion and wear.
Hard anodising (type III)
Hard anodising is a thicker variant to sulphuric anodising, with the typical thickness between 25 to 60µm thick although it is possible to go thicker than this. Will conform to MIL-A-8625, Type III, Class 1/2.
Black brightened
A slightly crackled smooth surface texture.
Clear Natural
A slightly crackled smooth surface texture with grey appearance.
Matte Black
A slightly crackled grainy and pitted surface texture.
Metal plating
Metal plating provides a uniform thickness coating, which offers protection from corrosion, oxidation and wear. Parts will appear brighter than in photos and are reflective. Plating thickness ranges are typically between 10µm to 25µm depending on the type of plating.
Electroless Nickel Plating
Excellent for corrosion resistance, very cost effective. Has slight reflective surface.
Chrome Plating
Highly reflective and evenly applied surface finish, similar to mirror polish.
