Matte Black Multi-Cavity Step Groove Aluminum Profile for High-End System Door Window Frames & Curtain Wall Systems

Designed for modern architectural systems and industrial applications, this matte black multi-cavity step groove aluminum profile combines an integrated hollow structure with preformed mounting channels. Its design supports the installation of glass, hardware, and sealing components while reducing the need for additional groove machining.

Manufactured from 6063-T5 aluminum alloy, the profile offers a balance of structural strength, lightweight construction, and corrosion resistance. The multi-cavity configuration supports thermal insulation, while the stepped mounting grooves and multiple sealing channels facilitate component integration in door and window systems.

The matte black powder-coated finish provides a contemporary appearance and an additional protective surface layer. Alternative finishes, customized dimensions, precision cutting, CNC machining, and extrusion die development are available for project-specific requirements.

Product Features

Integrated Multi-Cavity Construction

The hollow multi-cavity design combines several functional channels within a single extruded profile. Its uniform wall thickness helps maintain structural consistency, while the integrated construction supports resistance to wind pressure and dimensional distortion under suitable service conditions.

Preformed mounting grooves accommodate relevant hardware, glass, and sealing components, helping reduce secondary machining and simplify assembly.

Stepped Mounting Grooves and Multi-Channel Sealing

The stepped groove configuration accommodates the installation of components with different thicknesses. Dedicated sealing channels can be used with compatible EPDM gaskets to support waterproofing, dust resistance, and sound insulation in door and window assemblies.

This design is suitable for system windows, architectural frames, and other applications requiring coordinated installation of multiple components.

6063-T5 Aluminum Alloy

The profile uses 6063-T5 aluminum alloy as its base material. Compared with steel components of comparable design, aluminum profiles can offer weight advantages while providing useful structural strength and corrosion resistance.

The lightweight construction can help reduce the load associated with building components and make transportation, handling, and installation more manageable.

Matte Black Powder-Coated Finish

The textured matte black surface provides a clean, understated appearance for contemporary architectural and industrial designs. Powder coating offers an additional protective layer against environmental exposure, UV radiation, and surface scratching.

Available surface options include mill finish, anodizing, and customized colors, subject to project specifications.
