In the aluminum profile industry, product performance is defined not only by alloy and dimensions, but largely by the surface treatment.
In a global market where each country presents unique environmental conditions—coastal humidity and salt spray, high-altitude UV radiation, tropical moisture, industrial pollution—selecting the appropriate finish becomes crucial for ensuring long-term durability, color stability, and overall product lifespan.
1. Coastal or High-Humidity Regions
Examples: Chile, Peru, Ecuador, Southern Argentina
Challenge: salinity, constant moisture, accelerated corrosion.
Recommended treatment:
-High-performance powder coating (≥60–80 μm)
-Enhanced adhesion and film thickness control
-Salt-spray corrosion testing according to international standards
Our solution: customized powder formulations engineered for marine environments to ensure long-term stability for windows, doors, and facade systems.
2. High-Altitude or High-UV Regions
Examples: Bolivia, Northern Chile, Mexico
Challenge: UV-induced fading and surface degradation.
Recommended treatment:
-Exterior-grade UV-resistant polyester coating
-PVDF coating for premium architectural projects (15–25 years of color stability)
Our solution: coating formulations adjusted to the UV index of the destination country, ensuring stable performance under extreme radiation.
3. Tropical Humid Climates
Examples: Brazil, Colombia, Panama
Challenge: persistent moisture, risk of mold, condensation-driven corrosion.
Recommended treatment:
-Anodizing ≥12–15 μm
-Moisture-resistant exterior powder coatings
Our solution: multiple anodizing thickness options designed for high humidity and urban environments.
4. Hot Regions with Intense Solar Exposure
Examples: Middle East, Northern Mexico, arid regions in South America
Challenge: heat + sunlight causing fading and loss of gloss.
Recommended treatment:
-UV-resistant outdoor-grade powder coating
-PVDF for long-service-life architectural applications
Our solution: coating systems customized based on annual sunlight hours and temperature profiles of each market.
5. Industrial or Chemically Aggressive Areas
Examples: factory zones, industrial parks, chemical exposure environments
Challenge: exposure to industrial gases, chemical particles, corrosive agents.
Recommended treatment:
-Medium-to-thick anodizing
-High chemical-resistance PVDF coating
Our solution: reinforced finishes specifically designed for industrial facilities and public-infrastructure projects.
6. Residential Design-Focused Markets
Examples: Argentina, Uruguay, Chile
Challenge: aesthetics + durability in outdoor environments.
Recommended treatment:
-Exterior-grade woodgrain thermal-transfer finish
-Transparent top-coat for added UV and weather resistance
Our solution: a wide selection of woodgrain patterns tailored to local residential and architectural design trends.

In the aluminum profile industry, product performance is defined not only by alloy and dimensions, but largely by the surface treatment.
When it comes to aluminum profiles for doors, windows, and façades, surface treatment is one of the most important factors. Different markets—especially in the Middle East—have unique preferences for color consistency, corrosion resistance, and durability. Here are the most common finishing options:
In the fast-paced world of manufacturing, construction, and industrial design, the choice of materials can make or break a project. Aluminum profiles have emerged as the unsung hero—lightweight, durable, corrosion-resistant, and infinitely versatile. At [Your Factory Name], we don’t just produce aluminum profiles; we craft solutions that align with your goals, whether you’re building skyscrapers, designing automotive components, or innovating electronics. For over [X] years, we’ve been a trusted partner for businesses worldwide, turning raw aluminum into high-performance profiles that drive success.
Aluminum door and window systems are widely used in modern buildings because of their strength, durability, and clean appearance. But what truly defines the performance of a window is not just the aluminum profile—it is the entire system design.
At KANGDI ALUMINIUM, we specialize in the manufacturing of aluminum profiles for door and window systems, offering solutions that combine technology, design, and sustainability. With years of experience and a strong commitment to quality, we work alongside architects, builders, and distributors to develop efficient, durable, and aesthetically appealing projects. Below, we show how our aluminum profiles adapt perfectly to the different needs of the market
Recently, our company has officially moved to its new factory site, marking a crucial milestone in the company's development journey and injecting strong impetus into the further development of the aluminum processing industry.
