Preferential selection of galvanized sheet:
Inland buildings with limited budget (such as factory fences and ordinary decorations).
High-rigidity load-bearing structures (such as shelves and mechanical bases) are required.
Preferred aluminum alloy: Highly corrosive environment (coastal chemical plants, ships, acid rain areas).
Lightweight requirements (automobile body, aviation parts).
Maintenance-free scenes (outdoor walkways, long-term exposure facilities).
Enhancement scheme: Galvanized sheet +PVDF coating: the service life is extended to 20 years (such as bus shelter). Aluminum alloy+fluorocarbon spraying: resistant to environment (offshore platform).
