What is an Open Back Aluminium Frame?
An open back aluminium frame is a specialized type of aluminium profile manufactured through high-precision extrusion processes. According to architectural literature and standard manufacturing criteria for aluminium extrusion, open back profiles are engineered with an open rear channel along the cross-sectional length. This structural configuration provides easy technical access during corner screw assembly and seamless integration with snap cover trims or secondary structural profiles on building wall openings.
The primary raw material utilized in producing these profiles is architectural-grade aluminium alloy. Under standard building material classifications, 6063-T5 aluminium alloy serves as the benchmark due to its balanced structural strength, environmental corrosion resistance, and excellent formability. The open section of the profile facilitates glass or infill panel adjustments without requiring the complete dismantling of the perimeter framework.
Deploying open-back aluminium frames offers practical solutions for construction professionals. These frameworks serve as primary perimeter supports for doors, window systems, and glass partition walls. Their versatile cross-sectional characteristics make them a preferred choice across shophouse developments, corporate office towers, modern residential projects, and commercial spaces. PT Elite Jaya Mandiri supplies these products to ensure dimensional precision and clean structural aesthetics for your project.

The open back screw pocket aluminium frame 4 inch variant is specially designed with a dedicated glass/panel insertion pocket channel. This design facilitates glass setting, producing a neat, secure finish that integrates smoothly into overall building architecture.
Difference Between Open Back and Other Aluminium Frame Types
Understanding the operational distinctions between profile types is vital for architects and procurement officers during building opening specification planning. Every aluminium frame section is designed for specific assembly positions within window and door systems.
Compared to a closed aluminium frame, which features a four-sided fully enclosed box section, the open back profile possesses an open channel that allows direct tool and screw access for corner joining. Closed profiles are typically positioned on fully exposed outer perimeter edges, whereas open back profiles are deployed where complementary snap-on covers or sub-frame assemblies are installed.
Distinct differences also exist when comparing open back to M section aluminium frames or Z/L section aluminium frames. M and Z/L profiles are primarily utilized for specialty rebate detailing or insect screen sash frames. In contrast, the open back profile serves as the primary structural perimeter frame for wall openings.
Furthermore, in thick glazing configurations, installers frequently combine open back profiles with glass bead aluminium frame systems, adding supporting aluminium frame components and aluminium door jamb profiles to ensure full sealing and structural integrity. Explore all options across our full aluminium frame catalog.
Functions of Open Back Aluminium Frames
Open back profiles fulfill critical functional roles in modern architectural building construction. Key functions of this product within opening systems include:
- Forming primary perimeter frameworks in wall openings for window and door unit installations.
- Providing structural support for glass panels, aluminium composite panels (ACP), or timber infills.
- Streamlining profile-to-profile corner joining due to internal screw port access.
- Enabling flexible integration with clip-on snap cover profiles and mullion extensions.
- Creating clean architectural reveals between brick masonry or concrete walls and window/door units.
- Serving as the mounting base for heavy-duty hinges, locks, and window/door hardware accessories.
Benefits of Open Back Aluminium Frames for Projects
Selecting open back aluminium frames offers tangible operational advantages for construction project execution. From procurement management and technical perspectives, these profiles deliver multiple benefits:

Technical Specifications to Consider Before Ordering
To ensure selected products match your project's engineering and architectural designs, review the following specifications during procurement preparation:
- Nominal and Actual Dimensions: Determine whether the project specifies 3-inch (76.2 mm) or 4-inch (101.6 mm) modules along with required wall thickness.
- Profile Configuration: Select plain open back, screw open back, slim frame, or heavy-duty profile designs.
- Surface Finish Type: Specify between anodized (CA clear, black) or powder coating (white, dark brown, custom color) according to project guidelines.
- Glass & Hardware Compatibility: Match profile pocket width with planned glass thickness, hinge dimensions, and lockset cutouts.
- Bar Length Specifications: Confirm required standard bar lengths per extrusion to minimize cut waste on site.
- Accessories Requirements: Check necessary glazing gaskets, assembly screws, snap covers, and sealing accessories.
How to Select the Right Open Back Aluminium Frame
To streamline your aluminium frame procurement process and ensure optimal building performance, follow these selection steps:
- Identify Space Application: Determine if the opening is situated on an exterior facade exposed to weather or an interior partition.
- Match Wall Opening Scale: Specify 4-inch or heavy-duty profiles for tall, wide openings, reserving 3-inch or slim frame options for standard residential openings.
- Calculate Glazing Loads: For heavy, double-glazed, or thick laminated glass, select heavy-duty or deep pocket variants designed for higher load ratings.
- Choose Assembly Methodology: Select screw open back variants to accelerate corner joint assembly work in the workshop or field.
- Select Architectural Finishes: Use anodized black or dark powder coating for industrial modern concepts, and wood grain finishes for warm natural tones.
- Evaluate Procurement Volume: Calculate total linear meter requirements to secure bulk wholesale pricing from your aluminium frame distributor.
- Consult Supplier Technical Teams: Review shop drawings with PT Elite Jaya Mandiri specialists to confirm profile suitability.
