Unraveling the Mysteries of Color Coated Galvanized Steel Coils: Painted vs. Bare.

Coated galvanized steel coils play an important role in the construction industry. They provide durability, rust resistance, and aesthetic appeal to buildings. However, the question of whether to use painted or bare coils has been a point of confusion for many in the industry. In this article, we will explore the differences between painted and bare coils, examine their properties, and highlight their respective benefits and drawbacks.

Properties of Painted Coils.

Painted coils are obtained by applying a layer of paint on the galvanized steel surface. The paint acts as a protective layer, preventing corrosion and rust. Painted coils also provide a wide range of colors and textures, making them a popular choice for building exteriors and interiors. The paint used on these coils is typically polyester, silicone polyester, or plastisol, offering different levels of scratch and chemical resistance.

Properties of Bare Coils.

Bare coils are essentially galvanized steel coils without any additional coating. They have a metallic look, with a shiny silver appearance. The zinc coating on the surface of the bare coil provides excellent rust protection. Bare coils are often used in industrial settings where aesthetics are not a primary concern.

Benefits and Drawbacks of Painted Coils.

The primary benefit of using painted coils is the wide range of colors and textures available. This allows builders and architects to create unique and visually appealing structures. Painted coils are also easy to maintain and clean, with many paint options offering excellent resistance against dirt, chemicals, and UV rays.

However, painted coils are generally more expensive than bare coils. The paint may also scratch or chip, exposing the underlying galvanized steel and compromising the rust protection.

Benefits and Drawbacks of Bare Coils.

The main advantage of using bare coils is the cost savings since there is no additional coating required. They are also highly durable, providing excellent resistance against corrosion and rust. Bare coils are commonly used in industrial settings, where their metallic look is appreciated.

On the other hand, bare coils have limited options in terms of aesthetics. They are not as visually appealing as painted coils and can also be difficult to clean due to their lack of a protective layer.

Conclusion.

In conclusion, whether to use painted or bare coils comes down to the specific needs of each building project. For those in need of an affordable and robust solution, bare coils are the way to go. For those who want to add character and visual appeal to their building, painted coils are the better choice.
