It's bathing. Colored galvanized materials are produced by plating steel materials using an oxidative color-forming hot-dip zinc alloy bath containing titanium, manganese, or both and optionally other additives, and then adjusting the bath temperature and/or cooling conditions. By controlling and adjusting the degree of oxidation, various colors such as yellow, purple, blue, green, red, dark red, olive gray, golden yellow, and iridescent are produced. These products are expected to be in demand in fields such as steel towers, lighting balls, guardrails, temporary frames for work and exhibition, and exterior panels.

発色の内部との一体性が向上する。When rolling the zinc plate after leaving the casting machine, rolling may be carried out immediately after it emerges from the casting machine, followed by oxidation color development under heating, and then cooling, or alternatively, the zinc plate after leaving the casting machine may be rolled. After oxidative color development under heating and cooling, rolling may be performed. The latter method produces a smooth colored zinc plate with no surface roughness, but the colored layer tends to become brittle when it contains more than 0.5% by weight of Ti, so care must be taken when rolling. Post-rolling improves the integrity of the colored layer and the uncolored interior.
