How Fertech Prevents Rust – Inside Our Anti-Corrosion Process

In Kerala, with its humid air, heavy monsoons, and coastal salt exposure, rust is a real challenge for any metal product.

Ordinary steel windows often start corroding within a few years — especially in coastal areas like Kochi, Kozhikode, or Alappuzha.

At Fertech, we knew that if we wanted to be Kerala’s No.1 steel window manufacturer, we had to engineer a rust-proof solution that lasts for decades.

Here’s exactly how we do it.

1. We Start with the Right Material – TATA Galvano GI Steel

The journey begins with TATA Galvano GI steel, one of the most premium galvanized steel products in India.

1. GI stands for Galvanized Iron — a process where steel is coated with a layer of zinc to resist corrosion.
2. TATA Galvano is known for uniform coating thickness, smooth surface, and excellent rust resistance.

✅ This means our steel windows already have a built-in rust shield before we even start fabrication.

2. Advanced Laser-Cutting for Precision

Why does laser cutting help prevent rust?

1. Traditional cutting can leave rough edges that are more prone to corrosion.
2. Fertech’s laser-cutting technology gives smooth, sealed edges, minimizing exposure points where rust could start.

✅ This precision work ensures every frame is not just strong but also better protected.

3. MIG Welding for Strong, Sealed Joints

1. Rust often starts at joints where moisture gets trapped.
2. We use MIG (Metal Inert Gas) welding, which not only makes the joint stronger but also completely seals it from air and water exposure.

✅ This step makes our windows resistant to moisture infiltration — a key factor in Kerala’s climate.

4. Double Anti-Corrosion Treatment

After fabrication, every Fertech steel window undergoes two layers of anti-corrosion protection:

1. Chemical Surface Treatment – Removes microscopic impurities that could cause rust.
2. Anti-Corrosion Coating – Creates a barrier between the steel and environmental moisture.

✅ This is the stage that truly gives long-term rust prevention, even in salty sea air.

5. Premium Powder Coating

Finally, we apply powder coating, which is baked at high temperatures to form a tough, weather-resistant finish.

1. Unlike normal paint, powder coating doesn’t peel or chip easily.
2. It comes in multiple colors, including wood-finish textures for a traditional look.

✅ This coating not only adds beauty but also acts as the final armor against rust.

FAQs

Q: How does Fertech make rust-proof steel windows?

✅ By using TATA GI steel, laser cutting, MIG welding, anti-corrosion coating, and powder coating.

Q: Will my steel windows rust in coastal Kerala?

✅ Not with Fertech — our multi-stage process is designed for coastal and humid climates.

Q: How long will Fertech windows last without rust?

✅ With minimal care, they can last 30+ years rust-free.

Q: Do you offer wood-look rust-proof windows?

✅ Yes — we can powder coat in wood textures for traditional-style homes.

Rust is one of the biggest challenges for steel in Kerala — but with Fertech’s science-backed anti-corrosion process, you can have strong, beautiful, rust-proof windows that last for decades.

This is why homeowners, builders, and architects across Kerala trust Fertech as the No.1 name in steel window manufacturing.
