Custom Aluminum Extrusions & Profiles

Marcus supports custom aluminum extrusions for a wide range of industrial and OEM applications, including structural sections, housings, channels, brackets, frames, and application-specific profiles. The company also helps customers combine extrusion supply with machining, finishing, and assembly, making it easier to source complete components or sub-assemblies through one coordinated manufacturing partner.

Yes. Marcus provides in-house CNC machining for aluminum components using more than 20 machining centres, including 3, 4, and 5 axis equipment. This allows extruded profiles to be finished with precise holes, threads, slots, mating faces, and other critical features, with tolerances on key interfaces maintained to demanding production standards.

Marcus offers multiple finishing options for aluminum profiles, including anodising, powder coating, plating, blasting, polishing, chromation, and heat treatment. Parts go through pre-treatment steps such as degreasing and cleaning before finishing. Final batches can be tested for coating thickness, adhesion, and corrosion resistance, with certificates supplied to support quality documentation requirements.

Yes. Marcus provides both Type II anodising and Type III hard anodise as part of its in-house surface treatment capability. These finishes improve corrosion resistance, wear performance, and surface hardness, making them suitable for industrial, aerospace, and precision applications where durability and consistent batch quality are important.

Marcus supports new product development through a structured process that includes DFM collaboration, simulation-led review, material guidance, prototyping, trial runs, and validation activities. This approach helps customers refine profile designs before production tooling and scale-up, reducing risk while improving manufacturability, quality planning, and launch readiness for new programs.

Extrusion-related services are supported under Marcus's IATF 16949:2016 and ISO 9001 quality framework. Depending on the program, the company also applies supplier audits, FAIR inspection, APQP, and PPAP-based controls. In-house inspection and advanced metrology strengthen consistency across machining, finishing, and assembly stages for customers with strict documentation and traceability requirements.

Yes. Marcus can integrate aluminum extrusions into mechanical or electro-mechanical assemblies alongside machined, molded, stamped, or die-cast parts. Assembly services include sub-assembly, fastening, crimping, ultrasonic welding, inline inspection, and functional testing. This helps customers receive ready-to-install products instead of managing multiple suppliers and separate production stages.

Marcus supports customers in automotive, EV, aerospace, electronics, healthcare, energy, and broader industrial manufacturing sectors. Its capabilities are suited to programs that require controlled quality, repeatable production, and value-added secondary operations. This makes Marcus a practical partner for both prototype-stage development and ongoing OEM or Tier-1 supply requirements.
