تقديم المنتج
ASTM A653 G90 galvanized steel refers to the ASTM A653 specification. The zinc coating code G90 indicates that the total zinc coating density on both sides is 0.9 oz/ft² (average minimum value of three points on both sides) or 0.8 oz/ft² (minimum single point value on both sides).
ASTM refers to the American Society for Testing and Materials.
A-653 is one of its sub-standard numbers.
ASTM A653 is the standard specification for hot-dip galvanized iron alloys or galvanized steel sheets.
The core advantage of G90 coating: excellent corrosion resistance
The anti-corrosion ability of galvanized steel directly depends on the thickness and quality of the zinc layer.
Sacrificial protection: Even if the surface of the coating is scratched, zinc will preferentially oxidize over iron, thus protecting the internal steel substrate from rusting.
Long lifespan: G90 coating can provide decades of effective protection in most atmospheric environments (non extreme industrial or marine environments), significantly reducing maintenance and replacement costs.
Economic balance: Compared to thicker coatings (such as G115), G90 provides sufficient protection while being more cost-effective; Compared to thinner coatings such as G60, its protection life is longer.
