Aluminium Extrusion & Anodising Services

Yes. Extruded aluminium can be anodised to create a durable oxide layer that improves corrosion resistance, surface hardness, and appearance. Marcus offers both Type II anodising for standard protection and Type III hard anodise for higher wear demands. Proper pre-treatment, cleaning, and process control are important to achieve consistent colour, coating quality, and batch-to-batch performance on extruded profiles.

Type II anodising is a standard anodic coating used to improve corrosion resistance and appearance on aluminium parts. Type III, often called hard anodise, creates a thicker, harder surface suited to higher wear and more demanding industrial or aerospace applications. Marcus offers both options, helping customers match the finish to functional, durability, and performance requirements.

Yes. Marcus supports aluminium extrusions through its certified partner network and provides anodising through its in-house surface treatment capability. This combined approach helps customers simplify procurement, reduce coordination between separate suppliers, and maintain stronger quality oversight from raw profile sourcing through finishing, inspection, and shipment documentation.

Marcus supports customers in automotive, EV, aerospace, electronics, healthcare, energy, and industrial manufacturing. Aluminium extrusions and anodised components are commonly used where low weight, corrosion resistance, dimensional consistency, and durable surface performance matter. The service is suited to both functional industrial parts and precision components that require controlled finishing quality.

Marcus uses controlled pre-treatment steps including degreasing, acid cleaning, and conversion preparation before finishing. Finished parts are tested using recognised methods such as ASTM B117 salt spray, XRF coating thickness checks, and adhesion cross-hatch standards where applicable. Full batch certificates are provided on every shipment to support traceability and quality documentation requirements.

Yes. In addition to extrusion sourcing and anodising, Marcus offers in-house CNC machining and broader finishing support. This allows customers to combine precision machining, surface treatment, and even assembly under one supplier relationship. Consolidating these operations can improve dimensional control, reduce handling between vendors, and shorten overall project timelines.

Anodising improves aluminium by creating a durable oxide layer that becomes part of the surface rather than sitting on top of it. This helps increase corrosion resistance, wear performance, and surface hardness while supporting a cleaner, more consistent finish. For many industrial and precision applications, anodising also helps extend part life and reduce maintenance concerns.

Yes. Marcus serves customers across India, the United Kingdom, North America, Australia, Mexico, Vietnam, and other target markets. With headquarters in Coimbatore and a partner network spanning India, Vietnam, and China, the company is structured to support global sourcing strategies while maintaining certified quality systems, supplier oversight, and coordinated manufacturing execution.
