Aluminium vs GI Steel Roofing Sheet: Which Is Better for Your Building? | Luxarc Private Limited, Thrissur

When it comes to roofing, choosing the right material can make all the difference between decades of durability and costly maintenance. In Kerala’s humid and coastal climate — where roofs face heavy monsoon rains, salt-laden air, and intense sun — the debate between Aluminium roofing sheets and GI (Galvanized Iron) steel roofing sheets is more relevant than ever.

At Luxarc Private Limited, one of Thrissur’s most trusted roofing sheet suppliers, we help homeowners, builders, and contractors select the ideal roofing solution for their projects. Let’s dive deep into how Aluminium and GI steel roofing sheets compare in terms of performance, durability, and value.

🔹 1. Understanding the Materials

Aluminium Roofing Sheet

Aluminium roofing sheets are made from high-grade aluminum alloy. Known for being lightweight, corrosion-resistant, and reflective, they are an excellent choice for Kerala’s coastal and tropical environments.

Key Features:

• Extremely corrosion-resistant

• Lightweight and easy to handle

• Reflects heat effectively, keeping interiors cooler

• Long lifespan with minimal maintenance

---

GI Steel Roofing Sheet

GI sheets are made of steel coated with a layer of zinc through a galvanization process. This coating protects the steel from rust and corrosion, making it one of the most widely used roofing materials in India.

Key Features:

• High strength and rigidity

• Economical and widely available

• Can be color-coated for enhanced protection

• Suitable for both industrial and residential use

---

🔹 2. Strength and Durability

Verdict:
If your property is near Thrissur’s coastal areas like Chavakkad or Kodungallur, Aluminium roofing sheets are the better long-term investment due to superior corrosion resistance. For inland industrial structures, GI sheets offer better structural strength at a lower cost.

---

🔹 3. Weight and Handling

Aluminium sheets are almost one-third the weight of GI sheets, making them easier to transport, lift, and install. This reduces both labor costs and structural load on the building.

Verdict:
If your project involves complex or lightweight structures (like residential roofs, canopies, or sheds), Aluminium sheets are more suitable. For heavy, large-span roofs, GI sheets are stronger.

---

🔹 4. Thermal Performance

Kerala’s hot and humid weather makes thermal insulation a key factor.

• Aluminium sheets reflect sunlight effectively, keeping interiors cooler by 2–3°C on average.

• GI sheets, especially darker color-coated variants, can absorb more heat, which may raise indoor temperatures slightly.

Verdict:
For energy-efficient and heat-reflective roofing, Aluminium wins hands down.

---

🔹 5. Cost Comparison

Verdict:
If you’re looking for a premium, long-lasting roof, go with Aluminium.
If you’re working on a budget-conscious industrial or commercial project, GI roofing sheets offer great value.

---

🔹 6. Appearance and Aesthetic Options

Both Aluminium and GI sheets are available in color-coated finishes (PPGI / PPAL) with glossy, matte, or metallic textures.

• Aluminium sheets retain their color and shine longer since they don’t rust.

• GI sheets offer a wide range of finishes but may fade slightly over time in coastal weather.

Verdict:
For long-lasting aesthetics, especially for homes, villas, and commercial buildings, Aluminium roofing sheets offer superior appearance retention.

---

🔹 7. Eco-Friendliness

Aluminium is 100% recyclable, making it one of the most sustainable roofing materials available.
GI sheets are also recyclable, but the galvanization process is less eco-friendly.

Verdict:
If environmental sustainability is a priority — choose Aluminium.
