Great question!
Every PERGOLUX frame is constructed using double-coated, high-strength architectural 6063-T5 structural aluminum. We exclusively utilize an AkzoNobel powder finish that passes rigorous commercial quality tests:
- Perfect Adhesion Rating: Achieved a flawless 100/100 score in square grid testing. The finish is chemically integrated into the metal surface, making peeling or flaking under standard use physically impossible.
- High Surface Hardness: Tested to a score of 90, exceeding the required 80-point industry minimum. This provides a high-density barrier that resists scratches from assembly handling, hail, or wind-blown debris.
- Climate Adaptability: Successfully withstood metal stretching up to 6.3mm of expansion/contraction without structural cracking, ensuring the paint morphs naturally with extreme seasonal temperature shifts.
