Hot-dip galvanizing (HDG) is often used to protect steel from corrosion in some of the harshest environments imaginable, yet it provides maintenance-free longevity for decades.
G90 is a grade of galvanized sheet produced to ASTM A653. It has 0.90 oz/sq. ft. of zinc overall or 0.45 oz/sq. ft. per side and has been annealed after galvanizing to produce a surface that promotes good adhesion of paint.

To provide maintenance-free corrosion protection for decades, Hot-dip galvanized (HDG) steel is specified for SPC products.
HDG steel will patina over time, changing from the bright shiny silver into a uniform matte gray/silver. It is important to note the durability of galvanized coatings is not determined by the appearance, but rather by the zinc coating thickness.
Regardless of the external appearance of the coating initially, all galvanized pieces will protect steel from corrosion for decades.
