Our process adheres strictly to international standards such as ISO 9001 for quality management and relevant ASTM/ANSI specifications for material properties and structural performance.

Materials Selection and Preparation:

Typically, these systems are constructed from high-grade aluminum alloys (e.g., 6061-T6 or 6063-T5) or galvanized steel. Aluminum is favored for its exceptional strength-to-weight ratio, inherent corrosion resistance, and recyclability. Steel offers superior impact resistance and strength for high-security applications, often requiring additional protective coatings. Raw materials undergo rigorous inspection to confirm chemical composition and mechanical properties before entering the production line.

Fabrication Process Steps:

1. Cutting and Punching: Precision CNC (Computer Numerical Control) machines cut raw material extrusions or sheets to exact specifications for fence pickets, rails, and posts. Automated punching equipment creates precise holes for assembly, ensuring consistent panel dimensions and easy installation.
2. Welding (for Steel) or Mechanical Fastening (for Aluminum): For steel fences, components are meticulously welded using advanced MIG/TIG welding techniques, ensuring strong, clean joints. Aluminum systems often utilize mechanical fastening (e.g., self-tapping screws, hidden fasteners, or patented interlocking systems) to maintain structural integrity and allow for thermal expansion.
3. Surface Preparation: Before coating, all components undergo extensive cleaning and surface preparation. This includes degreasing, multi-stage washing, and phosphating or chromating treatments to enhance adhesion and corrosion resistance.
4. Protective Coating Application:
   • Powder Coating: Electrostatic application of polyester or epoxy-polyester powder, followed by high-temperature curing, creates a durable, weather-resistant, and aesthetically pleasing finish. This process adheres to AAMA 2604/2605 standards for superior exterior performance.
   • Hot-Dip Galvanization (for Steel): Steel components may be hot-dip galvanized after fabrication (ASTM A123) to provide a robust zinc coating, offering cathodic protection against corrosion. This is often followed by powder coating (duplex system) for enhanced longevity and aesthetics.
5. Quality Control and Testing: Throughout the manufacturing process, components undergo rigorous quality checks. This includes dimensional accuracy, weld integrity (non-destructive testing like ultrasonic testing), coating thickness, adhesion tests (cross-hatch adhesion), salt spray tests (ASTM B117) for corrosion resistance, and UV resistance testing to ensure color stability. Finished panels are inspected for visual defects and structural soundness.
6. Assembly and Packaging: Finally, panels are assembled (if not pre-assembled) and carefully packaged to prevent damage during transit, ensuring they arrive at the site in pristine condition.

The typical service life for our properly installed and maintained fence systems is between 20 to 30 years for powder-coated aluminum, and often exceeding 50 years for hot-dip galvanized and powder-coated steel (duplex system), far surpassing conventional fencing options.
