Surface finishing affects the functionality and appearance of metal products. Some finishes are more rugged than others, while the appearance of some is intended for decorative use.
What Is the Difference Between Type II and Type III Anodising?
Type II anodising is mainly chosen for appearance. It offers corrosion resistance and comes in various colours, making it suitable for visible parts. Type III anodising focuses on performance, creating a thicker, tougher surface that handles wear better and suits moving components.
Can Anodising Match Exact Colours?
Anodising is not paint, so exact colour matching can be difficult. The final shade depends on the metal alloy and how it reacts during processing. Colours can be close but not identical, so other finishes are often used when precision matters.
When Should Zinc Nickel Plating Be Used?
Zinc nickel plating is chosen when strong corrosion protection is required, particularly in harsh operating conditions.

What Is Alodine and Why Is It Used?
Alodine is used on aluminium to improve corrosion resistance while keeping conductivity. This makes it suitable for housings and grounding needs within sheet metal fabrication.
Is Powder Coating Better Than Wet Painting?
It depends on the application. Powder coating is durable and suits metal parts needing protection. Wet painting is better for fine detail or specific colours.
What Is Electropolishing Used For?
Electropolishing removes a thin surface layer to create a smooth finish. It is used in medical and food environments.
