Comparison Note: The Aluminum component in the Galvalume coating creates a stable barrier layer, making PPGL 2-6 times more durable than PPGI in most environments.
Application
High-End Roofing: Residential, commercial, and institutional buildings where service life is critical.
Industrial Structures: Factories, warehouses, and chemical plant sidings where exposure to corrosive elements is high.
Outdoor Furniture and Fixtures: Due to exceptional weather resistance.
Cold Storage Facilities: For structural integrity and resistance to condensation-related corrosion.
Advantages
Exceptional Lifespan: Offers the best long-term performance and minimal maintenance costs in harsh weather.
Superior Heat Reflectivity: The Galvalume coating reflects heat efficiently, contributing to energy savings when used for roofing.
Excellent Flatness: The coating process ensures a very flat surface, ideal for high-definition color finishes.
High Resistance to Rust Creep: Even if the surface is scratched, the Al-Zn alloy slows down the spread of rust significantly.
