Powder Coating Line Technical Specifications for Aluminum Door/Window Profiles
High-quality aluminum profiles for doors and windows must meet strict material standards, including minimum wall thickness of ≥1.4mm for window frames and ≥2.0mm for door frames, with mechanical properties achieving tensile strength ≥157 N/mm² and yield strength ≥108 N/mm², along with an anodized coating thickness ≥10μm. Non-compliant materials are considered substandard and unsafe for architectural applications.
Premium products feature CNC-machined joints, seamless assembly with airtightness testing, and smooth operation, while substandard products show irregular cutting marks, poor fitting with gaps >1mm, and operational friction risks.
Certified profiles cost 30%+ more due to precision extrusion tolerances (±0.1mm) and ISO-compliant powder coating (60-80μm). Avoid non-certified suppliers using undersized materials (0.6-0.8mm) or recycled aluminum with inconsistent alloy composition.
Always verify mill test certificates (MTC) and reject any profiles below 1.2mm, prioritizing manufacturers with Class A powder coating lines and BIM-compatible fabrication systems to ensure compliance with GB/T 8478-2020 standards for architectural aluminum profiles.
