Frequently Asked Questions
- Q: What is the difference between GI and GL (Galvalume) steel?
- A: GI (Galvanized Steel) uses a zinc coating, while GL (Galvalume Steel) uses an aluminum-zinc alloy coating. GL typically offers better corrosion resistance and heat reflectivity, while GI provides superior edge protection and is more economical for many applications.
- Q: What zinc coating weight should I choose for my project?
- A: For interior applications, Z40-Z80 is sufficient. For exterior and structural applications, Z120-Z180 is recommended. For highly corrosive environments (coastal, industrial), Z275 or higher is advised.
- Q: Can galvanized steel be painted?
- A: Yes. Galvanized steel can be painted after proper surface preparation. However, for architectural applications requiring color, we recommend using our prepainted steel (PPGI) products for superior finish quality.
