Powder Coating Engineering Standards
Standard Compliance: Profiles are tested according to Qualicoat Class 1 and AAMA 2603 standards.
Raw Material Sourcing: Pre-treatment uses a multi-stage chrome-free conversion coating to support coating adhesion.
Pre-treatment Process: Substrates undergo a multi-stage chrome-free conversion coating to ensure long-term adhesion performance.
Curing Control: Oven temperature is monitored by data-loggers during curing.
Custom Fabrication Capabilities
Precision mitering supports 45°–90° cutting for framing joints.
CNC machining allows custom slots, notches, and milling operations.
Secondary fabrication tolerances are controlled within ±0.2 mm.
TIG and MIG welding are available for structural sub-assembly joining.
Quality Control and Testing
Substrate Inspection
Ultrasonic testing is performed on 6063-T5 material before coating.
Impact Compliance
Drop weight testing at 2.5 Nm shows no cracking.
Corrosion Resistance
Salt spray exposure exceeds 1,000 hours with minimal creep, ensuring long-term outdoor stability.
Hardness Optimization
Indentation testing guarantees a minimum Webster hardness of 8 HW for scratch resistance.
Gloss Uniformity
Gloss variation is controlled within ±5% using digital gloss measurement.
