A572Gr60 H-beam galvanized layer
Characteristics of A572Gr60 H-beam galvanized layer Thickness: According to the standard, the coating thickness is usually between 50-150 microns, depending on the thickness of the steel and the galvanizing time. Corrosion resistance: The zinc layer provides sacrificial anode protection, effectively preventing the corrosion of steel in humid, acidic or salt spray environments. Adhesion: The low silicon content design of A572Gr60 makes it react moderately with zinc liquid, avoiding excessive thickness or peeling of the coating, and ensuring that it will not turn black after long-term use.
