Angle Brackets For Aluminum Frames

Manufacturing Process and Quality Control

As an experienced Aluminum Angle Bracket Manufacturer, our production flow includes mold design, extrusion, precision machining, surface finishing and multi-step quality inspection. Typical process steps:

  1. Die design and extrusion: Profile-specific dies are designed for accurate cross-section and material distribution.
  2. Machining: Cutting, punching/drilling, countersinking and chamfering to exact hole locations and tolerances.
  3. Surface finishing: Anodizing or powder coating to specified thickness and color requirements.
  4. Inspection: Dimensional checks, tensile or hardness testing, and surface quality checks before packing.
  5. Packing: Protective film / foam and neutral cartons for export shipments.
Inspection Item Requirement Method
Dimensional tolerance ±0.1 mm (typical) Digital calipers and inspection fixtures
Angle deviation ≤ ±0.5° Precision angle gauges
Tensile / strength Meets alloy specification (dependent on material) Universal testing machine
Surface film thickness ≥ 10 µm for anodized coatings (as specified) Coating thickness gauge
Note: Quality checks at each stage ensure Aluminum Profile Accessories meet both dimensional and performance requirements for demanding door & window applications.

Application in Window and Door Systems

In door and window assemblies, an Aluminum Profile Angle Bracket secures corner joints, maintains frame squareness, and contributes to the overall wind-load and sealing performance of the system. Typical application examples:

Application Function
Casement and sliding windows Fixes corner geometry and prevents frame distortion under load
Curtain wall systems Connects mullions and transoms for stable curtain support
Glass partitions Allows clean, secure connections between glass and profiles
Sunroom (conservatory) structures Provides reinforcement for long-span aluminum frames

Proper selection and correct installation of Angle Brackets For Aluminum Frames directly affect the sealing performance and lifetime of the door/window assembly.

Selection Guide: How to Choose the Right Angle Bracket

Selecting the correct Aluminum Profile Angle Bracket requires consideration of profile series, connection type, load requirements and surface treatment. Use the following checklist:

Selection Factor Guidance
Profile series Choose brackets that match the profile cross-section and slot geometry (20–60 series)
Connection style Internal vs external depends on desired appearance and access for maintenance
Load requirements For heavy doors or high wind loads, use reinforced or thicker brackets
Surface treatment Outdoor installations: anodized or specialized coating for corrosion resistance
Budget Light-duty brackets reduce cost for non-critical aesthetic frames; reinforce where safety or performance is required

If in doubt, consult structural or window system documentation to determine design loads and recommended connector types.
