Surface Finishes Options
Bead blasting
Bead blasting produces a clean, uniform matte finish and can remove surface contaminants or light burrs. It improves texture and prepares parts for further coating.
Anodising (type II)
Type II anodising provides corrosion resistance and allows color dyeing. It is suitable for decorative parts, lightweight components and products requiring a durable finish.
Hardcoat anodising (type III)
Type III hardcoat anodising creates a thicker, harder and more wear-resistant surface. It is ideal for industrial parts, hydraulic components and high-performance aluminum parts.
Powder coating
Powder coating provides a thick, durable protective finish with excellent scratch and impact resistance. It is widely used for metal parts, brackets and industrial components.
