Our specialist processes
High-quality finishing methods engineered for precision, performance, and durability across demanding industries.
Copper Chemical Blacking
Blacking copper creates a non-reflective, glare-reducing surface, it is a chemical conversion process that produces a darker finish,. The treatment reacts with the surface to form a stable, dark oxide/sulphide layer without adding measurable thickness, enhancing appearance while providing mild corrosion resistance. It can produce an antique-style finish on copper and copper-based alloys such as brass and bronze.
Zinc Finishing
A reliable coating that protects steel against corrosion, improves durability, and offers a clean, uniform finish for industrial use.
Sulphuric Anodising
A durable anodic coating applied to aluminium to improve corrosion resistance, wear protection, and surface appearance.
Passivation
A chemical process that removes contaminants from stainless steel surfaces, improving corrosion resistance and ensuring long-term stability.
Electroless Nickel
A uniform nickel coating applied without electrical current, delivering enhanced hardness, wear resistance, and surface protection.
Iridite
A chromate conversion coating that provides effective corrosion protection for aluminium components while improving paint adhesion.
Surtech 650
A reliable non-chrome conversion coating offering excellent corrosion resistance and a clean, consistent finish on aluminium surfaces.
Chemical Blacking on Mild steel or Stainless Steel
Chemical Blacking (also known as black oxide coating) is a chemical conversion process that produces a durable black finish on ferrous metals such as mild steel, stainless steel and tool steel. It enhances appearance, provides mild corrosion resistance (when sealed) and improves lubricity without affecting dimensions.
