Why Aluzinc Coating is a Game-Changer for Kenyan Roofs

In Kenya, where the climate varies from hot and humid coastlines to cooler highlands and arid savannahs, roofing materials must stand up to harsh environmental conditions. Corrosion, heat, rainfall, and salt exposure are some of the many elements roofs must withstand to remain durable and functional. This is where Aluzinc-coated roofing sheets come into the picture, offering a smart, long-term solution for homeowners, developers, and contractors alike.

At Kidani Mabati Factory, we take pride in providing top-quality Aluzinc-coated roofing products that combine durability, beauty, and performance. In this detailed article, we’ll explore what Aluzinc is, why it outperforms traditional galvanized sheets, and how it can benefit your roofing investment in Kenya.

What is Aluzinc?

Aluzinc is a coating composed of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon. This unique combination creates a superior protective layer when applied to steel, making it highly resistant to corrosion, heat, and other environmental stressors.

The aluminum in the coating provides a barrier effect, shielding the underlying steel from external elements. Zinc offers sacrificial protection, meaning it corrodes first to protect the steel. Silicon enhances adhesion between the coating and steel, ensuring long-term stability and resilience.

Benefits of Aluzinc Coating for Roofing in Kenya

1. Superior Corrosion Resistance

Kenya’s diverse weather systems can be unforgiving, especially in coastal areas where salt-laden air accelerates corrosion. Aluzinc outperforms traditional galvanized sheets by offering up to 6 times better corrosion resistance.

Whether you’re building in Mombasa, Kisumu, or upcountry towns like Nyeri and Eldoret, Aluzinc-coated mabati from Kidani ensures your roof stays intact and rust-free for decades.

2. Enhanced Lifespan

Roofs are a long-term investment. Aluzinc-coated sheets can last up to 30–40 years, significantly longer than standard galvanized iron sheets which may last only 10–15 years in harsh conditions.

This longevity translates into long-term savings on repairs, replacements, and maintenance.

3. Heat Reflectivity and Thermal Efficiency

Aluzinc’s reflective surface helps deflect a significant portion of solar radiation, keeping interiors cooler. This is especially valuable in hot areas like Turkana, Garissa, and Nairobi’s Eastlands, where heat can lead to increased energy consumption through air conditioning.

By reducing indoor temperatures, Aluzinc roofing promotes energy efficiency and a more comfortable living environment.

4. Aesthetic Appeal

Aluzinc-coated sheets have a sleek, silvery finish that retains its shine for years. At Kidani Mabati, we also offer color-coated Aluzinc sheets in both matte and glossy finishes to match your architectural taste and design preferences.

This makes Aluzinc not just a functional upgrade but an aesthetic enhancement for both residential and commercial buildings.

5. Fire Resistance

Unlike some roofing materials that may ignite or deform under high temperatures, Aluzinc-coated sheets are fire-resistant. The aluminum-zinc alloy performs well under extreme heat, providing additional safety for buildings in fire-prone regions or areas near forests and dry grasslands.

6. Cost Efficiency Over Time

While Aluzinc-coated mabati may have a slightly higher upfront cost than galvanized options, the total cost of ownership is significantly lower. With fewer repairs and a longer replacement cycle, homeowners and developers enjoy better value for money.

Where Aluzinc Roofing Excels in Kenya

Coastal Regions (e.g., Mombasa, Lamu)

Salt air accelerates corrosion, making Aluzinc a superior choice for long-term protection.

High-Rainfall Zones (e.g., Kisii, Kakamega)

Aluzinc’s water-shedding properties and corrosion resistance make it ideal for wet climates.

High Heat Zones (e.g., Turkana, Garissa)

Its reflective qualities help keep buildings cool, reducing energy bills.

Urban Projects (e.g., Nairobi, Nakuru)

For residential estates, schools, hospitals, and commercial buildings, Aluzinc adds both durability and curb appeal.

Expert Tips When Buying Aluzinc Roofing in Kenya

1. Verify the Coating: Always ensure the product is labeled as Aluzinc or AZ150, which indicates the coating weight. At Kidani, our sheets meet or exceed this standard.
2. Check Gauge Thickness: For residential use, 28 gauge is common; heavier structures may require 26 or 24 gauge. We help you match gauge to use case.
3. Inspect the Finish: A smooth, shiny or uniformly matte surface is a sign of quality. Kidani’s finishes resist fading, chalking, and corrosion.
4. Ask for Warranty: Reputable suppliers like Kidani offer warranty-backed products, demonstrating our confidence in durability.
5. Professional Installation Matters: A premium sheet installed poorly can perform badly. We can connect you with trained installers familiar with our products.
