Bi mu nekkee raccord buy yobbu sargal, màndarga mekanik yu mag yi ci plaque yoke asiye galvanisé ñooy dooley traction, dooley rendement, guddaay, dëgëraay ci impact, ak dëgëraay. Macceer yiñ gëna xam ñooy Q235B, Q355B, ASTM A36, ak A572 Gr50, ñoom ñépp ay asiye yu néew karbon lañu. Tàngooru galvanisasioŋ bu tàng mingi tollu ci 440 ba 460 degre, ci suufu tàngooru recrystallisation bu asiye bi, kon du wàññi bu baax dooley macceer bi. Coppite ci dooley traction dafay nekk<5%, generally maintaining factory-set levels. Yield strength fluctuates slightly but remains generally stable. Due to the high-temperature tempering effect, internal stress is slightly released, and plasticity is slightly improved. Short-term high-temperature holding causes a slight decrease in surface hardness, which does not affect the overall load-bearing capacity.
