When you buy a car, you look at the mileage. When you buy a roof, you should look at the Erosion Rate. Every year, the sun, rain, and wind slowly “eat away” at a roof’s surface. Ordinary galvanized sheets have a high erosion rate, meaning they thin out quickly. At Kanakdurga Technokraft India, we have engineered our KD Sheets with Improved Erosion Coating to ensure they last for decades, not just seasons.
The Science of Erosion Resistance
The erosion resistance of a KD Sheet comes from its unique Aluminum-Zinc (Al-Zn) alloy.
-
The Barrier Effect: Aluminum is incredibly stable. When exposed to the air, it forms a thin, invisible layer of aluminum oxide that is almost impossible for corrosion to penetrate.
-
The Slow-Release Guard: The Zinc in our alloy provides sacrificial protection, but because it is blended with Aluminum, it dissolves at a much slower, controlled rate than in traditional GI sheets.
Why Longer Life Matters
A roof that erodes slowly maintains its Weight Tolerating Capacity for a longer period. An ordinary sheet might start at 0.50mm but erode to 0.40mm in just five years, making it dangerous to walk on. A KD Sheet stays thick and strong, maintaining its 550MPa yield strength year after year.
Conclusion
Don’t buy a roof that disappears with the rain. Invest in the Improved Erosion Coating of KDT India and enjoy a “Long Life” roof that protects your family for over 30 years.
