Is a Galvanized Steel Perforated Sheet with Spangle Better than One Without?

When purchasing galvanized steel perforated sheets, customers often notice that some have spangles on the surface, while others do not. So, is there a quality difference between the two, and which one is better?
Galvanized Steel Perforated Sheet
What Are Spangles?
Spangles are the unique crystallized patterns that form on the surface of galvanized steel during the natural cooling process of the zinc coating. For instance, traditional household galvanized buckets often displayed visible spangle patterns. Spangled galvanized sheets are typically used in construction and other applications where direct contact with the human body is limited.
What Is Non-Spangled Galvanized Steel?
Non-spangled galvanized steel is produced through specialized manufacturing techniques. For example, by controlling the lead content in the zinc pot or applying post-zinc bath treatments—such as small spangle control processes or zinc powder spraying—the spangle size can be minimized to create a smooth, uniform surface, resulting in non-spangled products.
Comparison Between Spangled and Non-Spangled Sheets
1. Quality: There is no difference in performance between spangled and non-spangled galvanized perforated sheets. Both offer the same level of corrosion resistance and durability.
2. Appearance: The primary difference lies in the surface finish. Non-spangled sheets have a more uniform and refined appearance, making them ideal for decorative or aesthetic applications.
3. Applications: For decorative uses (e.g., curtain walls or interior design), non-spangled sheets are recommended, and customers should specify this requirement during procurement. For functional purposes such as filtration or screening, both types perform equally well.
The quality and performance of spangled and non-spangled galvanized steel perforated sheets are identical, with the difference mainly being in their appearance. Customers should select the appropriate type based on their specific application needs, especially if appearance is a key consideration.
