Product Introduce<\/h2><\/div>\n\n\n\n

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\/ft\u00b2 (average minimum value of three points on both sides) or 0.8 oz\/ft\u00b2 (minimum single point value on both sides).<\/p>\n\n\n\n

ASTM<\/a> refers to the American Society for Testing and Materials.<\/p>\n\n\n\n

A-653 is one of its sub-standard numbers.<\/p>\n\n\n\n

ASTM A653 is the standard specification for hot-dip galvanized iron alloys or galvanized steel sheets.<\/p>\n\n\n\n

The core advantage of G90 coating: excellent corrosion resistance<\/strong><\/p>\n\n\n\n

The anti-corrosion ability of galvanized steel directly depends on the thickness and quality of the zinc layer.<\/p>\n\n\n\n

Sacrificial protection:<\/strong> Even if the surface of the coating is scratched, zinc will preferentially oxidize over iron, thus protecting the internal steel substrate from rusting.<\/p>\n\n\n\n

Long lifespan:<\/strong> G90 coating can provide decades of effective protection in most atmospheric environments (non extreme industrial or marine environments), significantly reducing maintenance and replacement costs.<\/p>\n\n\n\n

Economic balance:<\/strong> 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.<\/p>\n\n\n\n
