RAL Charcoal Powder Coated Aluminum Window Profiles for Sliding System

We achieve a meticulously controlled, uniform sand grain pattern across all aluminum extrusions. This consistency is crucial for large door and window installations, ensuring a seamless visual flow without patchy or uneven textures. The fine-grade powder fuses smoothly to complex profiles, covering edges and corners effectively to deliver a cohesive, high-quality appearance on every finished product.

Engineered for practical longevity, this textured coating is highly resistant to harsh weather conditions, including rain, humidity, and temperature fluctuations. Its non-porous surface prevents dirt and grime from embedding deeply, making routine cleaning simple—often requiring just a wipe with a damp cloth. This makes it an ideal, low-maintenance choice for both interior and exterior doors and windows.

The understated elegance of the sand grain finish adds a touch of sophistication without being ostentatious. It is equally suitable for residential homes, seeking a warm and inviting atmosphere, and commercial buildings, requiring a professional and robust aesthetic. The texture reduces light glare on surfaces, contributing to visual comfort, while its neutral tone pairs well with a wide range of frame colors and architectural styles.
