Aluminum panels are widely used in building facades of office towers, airports, and metro stations. But many clients often raise the same concerns:

During production and shipping, the panels take up a lot of space and are difficult to transport. Once installed outdoors, they face long-term exposure to wind, sunlight, and rain — leading to fading and uneven color over time.

We’ve been in this industry for more than ten years and have received many similar inquiries. The real issue lies in the aluminum itself — it’s prone to oxidation and corrosion, and traditional liquid coatings don’t provide sufficient weather or adhesion resistance.

That’s why we usually recommend epoxy powder coatings.

They’re more compatible with aluminum’s properties, offering excellent weatherability and UV resistance, helping panels stay stable and vivid in outdoor conditions.

This makes them especially suitable for exterior walls, public buildings, and outdoor structures. Epoxy powder coatings can last for more than 20 years without maintenance, are environmentally friendly, non-toxic, and highly material-efficient.

Some leading powder manufacturers even achieve a reuse rate of over 99% for overspray powder. They combine primer and topcoat in one layer, making automated application simple and efficient. The coating forms a dense film with strong adhesion, impact resistance, and flexibility, while also providing excellent chemical corrosion resistance and electrical insulation performance.
