The lowest cost among three corrugated sheets, perfect for budget-limited temporary construction projects;
Excellent bending and punching performance, no cracking during on-site secondary processing;
Basic zinc coating isolates moisture and steel base to avoid rust in dry inland environments;
No paint layer, free from paint aging and peeling under long-term sun exposure.
Poor salt spray resistance, only 500-1000 hours salt spray test duration, easy to rust in coastal areas;
Single silver-gray metal appearance without decorative effect for building facades;
Cannot resist acid and alkali gas corrosion, not applicable for chemical industrial zones.
Superior salt spray and moisture resistance, service life up to 30-50 years in Southeast Asia coastal areas;
Excellent high temperature resistance, suitable for high-temperature workshop roofing;
Automatic scratch repair performance, minor installation scratches will not cause rust spots;
Zero later maintenance cost without paint layer aging and peeling troubles.
Bare metal surface without colored decoration, unable to meet architectural appearance requirements;
25% higher purchase cost than ordinary galvanized corrugated sheet;
Strong light reflection affects indoor natural lighting under direct sunlight.
Integrated anti-corrosion and decorative functions with multiple classic colors for neat building appearance;
20-30 years service life under conventional outdoor environments, balancing cost and durability;
Direct installation without on-site painting, greatly shortening construction period;
Suitable for inland and mild coastal areas, applicable for both roof and wall enclosure.
Paint surface is easy to be scratched by hard objects during transportation and installation;
Slow paint fading under long-term UV radiation, poor performance in strong chemical corrosion environment;
Paint cracking risk after large-angle bending processing.
