For aluminum window profiles, stable profile quality is an important factor to ensure the success of the project. Quality is our manufacturing criterion.
We support ODM/OEM, provide one-stop aluminum profile production services, have a variety of standard aluminum profile specifications of extrusion dies, and produce your aluminum profiles according to demand with competitive price costs.
The quality of window aluminum profiles is determined not only by material selection and extrusion precision but also critically by surface treatment. We provide comprehensive surface finishing solutions including anodizing, electrophoresis, powder coating, PVDF fluorocarbon coating, and wood grain finishes.
The aluminum profiles are immersed in an acidic solution and undergo electrolytic oxidation to form an oxide film. Anodizing enhances the corrosion resistance, hardness, and surface smoothness of the aluminum profiles. It can also be used with dyeing agents to achieve different colors.
Class of oxide film: AA10; AA15; AA20
Surface type: Matte; flat
Color: Silver white; bronze; champagne
Fetures: Corrosion resistant; durable; shining and decorative
The charged aluminum profiles are immersed in a coating solution in an electrolytic tank. Through electrophoresis, the coating evenly adheres to the aluminum surface. Electrophoretic coating provides good weather resistance, color stability, and a smooth and uniform coating.
Corrosion resistance of composite film: ≥9.5 level
Paint film cohesive: Zero lever
Paint film hardness: ≥3H
Surface: Matte; flat; high brightness
Color: Silver white; bronze; champagne
Features: Corrosion resistant; durable; smooth and shining
Powdered coating material is sprayed onto the aluminum profiles, and then melted and cured at high temperatures. Powder coating offers durability, corrosion resistance, and a pleasing appearance. It is also environmentally friendly.
Coat thickness:40-120um
Coat shock resistance: No cracking or fall off after shock test
Coat cohesion: Zero lever
Surface type: Highly glossy; semi glossy; matte

An aluminum window profile is an extruded section of aluminum designed to form the frame, sash, and structural support elements of a window system. These profiles are engineered to accommodate glass panels, weather sealing, hardware fittings, and drainage paths. Their design varies depending on the window type—such as sliding, casement, or tilt-and-turn—and performance requirements like insulation or load-bearing capacity.
Aluminum window profiles offer high structural strength with low weight, making them ideal for modern building envelopes. They are corrosion-resistant, require minimal maintenance, and support narrow frame designs for maximized glazing area. Aluminum profiles are also recyclable and compatible with various surface finishes for both commercial and residential use.
The most commonly used alloys for window profiles are 6063-T5 and 6061-T6.
Surface finishes improve both durability and appearance. Common options include:
Surface finish also affects color retention, ease of cleaning, and resistance to wear.

Aluminum profiles are used in a wide range of window systems, including:
Each type requires specific profile geometry for hinges, sliders, gaskets, and glazing.
There are several techniques you can use to connect windows and doors aluminum profiles. However, the most suitable one is dependent on the actual framing design of the specific window or door.Common Methods to Connect Aluminum Profiles for Windows
1. Mechanical Fasteners (Screws, Bolts, and Nuts)
This traditional method involves fastening profiles together using self-tapping screws, machine screws, or bolts. Screw ports are often built into the extrusion design.
Advantages: Simple, reliable, allows disassembly
Limitations: Visible screw heads may require cover caps; can loosen over time if not properly torqued
Best for: General window frame assembly in residential and commercial applications
Best Practice: Provide clearance for screw heads and pre-design threaded ports to streamline assembly.
2. Internal Cleats and Corner Keys
Cleats or corner keys are inserted into dedicated chambers within the aluminum profile and secured via friction or fasteners. Often made from aluminum, steel, or reinforced plastic.
Advantages: Concealed, clean finish, supports air-tight and water-tight construction
Limitations: Requires precision in slot tolerances
Best for: High-performance and visually refined window systems
3. Angle Brackets and Connection Plates
External or internal brackets, typically at 90° or 45° angles, join two profiles at a corner. These are screwed into the profiles using designated anchor points.
Advantages: Strong load-bearing capacity, customizable angles
Limitations: May require cover caps to conceal brackets
Best for: Non-standard window shapes or high-wind-load areas
4. Welding (TIG or MIG)
Thermal welding fuses aluminum profiles into a seamless joint, used mostly in structural or industrial-grade windows.
Advantages: Permanent, extremely strong
Limitations: Requires specialized equipment and skilled labor; not reversible
Best for: Large-format or load-bearing frame systems (e.g., curtain walls)
5. Snap-Fit and Interlocking Systems
Profiles are designed to clip or slide together using integrated barbs or grooves. This allows fast, tool-free assembly.
Advantages: Quick installation, clean aesthetics
Limitations: Requires precision in profile extrusion; limited strength for heavy-duty applications
Best for: Modular window units and minimalist designs
6. Nut Track / T-Slot Fastening
These profiles have internal channels that accept nuts or bolt heads. Fasteners can be positioned anywhere along the slot.
Advantages: Flexible positioning, reduces the need for pre-drilled holes
Limitations: Only applicable to profiles with T-slots
Best for: Curtain walls and adjustable modular systems
7. Hinge and Articulated Joints
Used specifically for operable windows such as casement, awning, or pivot types. Hinges are attached directly to the frame profiles.
Advantages: Enables movement, cycle-tested durability
Limitations: Load limitations; specific to operable sashes
Best for: Windows that require frequent opening and closing
8. Anchor Connectors and Expansion Screws
These are used to fix entire window frames into the surrounding wall structure. They ensure base-level anchoring and long-term stability.
Advantages: Secures frame to building envelope
Limitations: Not used for profile-to-profile connection
Best for: Site installation of completed window units
Yes. We support custom profile design for unique window systems. This includes adjustments to profile cross-section, wall thickness, glass channel size, and thermal break integration. Custom tooling can be developed based on your drawings or project requirements. We also maintain a library of standard dies for quick manufacturing.
A thermal break profile incorporates a non-metallic insulator—usually a polyamide strip—between the inner and outer aluminum sections. This design reduces heat transfer, improves energy efficiency, and minimizes condensation. Thermal break window profiles are commonly used in climates where thermal insulation is important.
The manufacturing of aluminum window profiles involves several key steps:
Extrusion: Raw aluminum billets are heated and forced through a shaped die to create continuous profiles with the desired shape.
Cooling and Cutting: The extruded profiles are rapidly cooled and then cut to specific lengths.
Machining: CNC machines cut, punch, and route profiles to create holes and notches for hardware installation.
Surface Treatment: Profiles undergo anodizing, powder coating, or painting to enhance corrosion resistance and aesthetics.
Assembly: Profiles are assembled into frames and sashes using fasteners or welding, with thermal breaks added for energy efficiency.
Glazing and Final Assembly: Glass panes are fitted into the frames, sealed, and inspected for quality before packaging.
Profiles can accommodate various glass configurations, including:
Glass bead profiles and gasket systems are selected based on thickness and performance needs.
We manufacture according to international standards such as:
These standards ensure dimensional precision, mechanical properties, and surface treatment quality across all aluminum window profiles.
Aluminum window profiles are used in:
They are suitable for both exterior and interior applications requiring long-term performance.
