Types of Corrugated Iron and How to Choose the Right One for Your Project

Corrugated zinc is one of the most popular roofing materials in the construction world. Besides being affordable, this material is also known for its durability, light weight, and ease of installation. However, corrugated zinc comes in various types, thicknesses, and shapes, so the selection must be tailored to the project's needs for optimal construction results.

Here's a complete explanation of the types of corrugated zinc and how to choose the most appropriate one for your project.

Types of Corrugated Zinc
1. Regular Corrugated Zinc (Zinc)
This zinc is made with a zinc coating that provides basic anti-rust protection. It is the most economical and is widely used in simple buildings.

Advantages:

• Affordable
• Lightweight and easy to install
• Suitable for:
• Temporary storage
• Non-permanent buildings
• Small-scale roof coverings

2. Galvanized Zinc
Has a thicker zinc coating than regular zinc, making it more rust-resistant and resistant to tropical weather.

Advantages:

• More durable
• Better protection against corrosion
• Suitable for:
• Residential homes
• Kiosks and shophouses
• Long-term construction projects

3. Galvalume Zinc (Zincalume)
Uses a mixture of zinc and aluminum, making it much more resistant to rust. It is lightweight, resistant to cracking, and very strong.

Advantages:

• Rust-resistant up to 3–6 times longer
• Stronger than galvanized steel
• Resistant to heat and extreme weather

Suitable for:

• Factories
• Warehouses
• Large commercial buildings

4. Color-Coated Corrugated Zinc
Zinc coated with a special paint for an aesthetic appearance and added weather protection.

Advantages:

• More attractive appearance
• Color coating helps prevent corrosion
• Reduces heat

Suitable for:

• Modern homes
• Canopies
• Shops and commercial buildings

5. Fiberglass/Polycarbonate Zinc
A transparent type of zinc that allows light to enter the room.

Advantages:

• Transmits light
• Unbreakable
• Lightweight

Suitable for:

• Greenhouses
• Parking areas
• Spaces requiring natural lighting

How to Choose the Right Corrugated Zinc for Your Project
1. Adapt to the Project Environment
If the area is near the coast or humid, use galvalum or galvanized steel, which is more corrosion-resistant.

2. Determine the Required Thickness
The thicker the steel, the stronger it will be at withstanding wind and loads.
Generally available thicknesses range from 0.25 mm to 0.45 mm.

3. Consider the Type of Load and Structure
For large buildings, use thick galvalum steel.

For small buildings, zinc is sufficient.

4. Consider Aesthetics
For modern residences and shophouses, choose colored corrugated iron for a more attractive appearance.

5. Adjust Your Budget
Zinc corrugated iron is more affordable, while galvalum and color-coated iron are more premium and durable.

Conclusion
Each type of corrugated iron has different functions and characteristics. Choosing the right one will help improve the structural strength, building appearance, and roof lifespan. Be sure to choose based on project needs, weather conditions, and budget.
