Cheap vs Expensive Corrugated Iron, What's the Difference?

Corrugated zinc is one of the most common materials used in construction projects, especially for roofing and building covering needs. However, in the market we often find very varied prices for this product. So, what actually differentiates cheap and expensive corrugated zinc?

1. Material Thickness and Weight
The main difference lies in the thickness of the zinc plate itself. More expensive corrugated zinc usually has a greater thickness, so it is automatically heavier and more durable. On the other hand, thin zinc tends to be more easily dented, torn, or damaged due to extreme weather.

2. Protective Layer (Coating)
High-quality zinc generally has an additional protective layer such as zincalume or galvanized which functions to inhibit rust. This layer is very important especially for buildings located in humid areas or near the coast. Cheap zinc usually has a thin layer or is not coated at all, so it is easy to corrode.

3. Precision and Neatness of Waves
In more expensive corrugated zinc products, the wave shape is more precise and neat, making it easier to install and produce tighter joints. This can prevent leaks and speed up work time.

4. Weather Resistance
Thicker zinc coated with a protective layer will be more resistant to sun heat and heavy rain. Extreme temperature changes will not quickly cause this material to expand or shrink excessively. In the long run, this saves maintenance and replacement costs.

5. Warranty and Certification
Quality zinc products are generally accompanied by SNI certification and a factory warranty. This not only guarantees quality, but also shows the manufacturer's commitment to product quality.

So, Do You Need to Choose the Expensive One?
It doesn't always have to be expensive, but choose corrugated zinc that suits the needs of the project. For long-term buildings or areas exposed to extreme weather, it is recommended to use higher quality zinc. However, for temporary needs or non-permanent buildings, more economical zinc can be an alternative.
