WOOIL STEEL, Technology is Our History.
Electro Galvanized Coil(EGZ)
가공성(Machinability)
용융 강판과 달리 외부의 열적 영향을받지 않아 소재의 기계적 물성을 그대로 유지하고 박리 현상을 일으키지 않아 어떠한 성형 및 프레스 가공에 의한 품질 변화가 없습니다.
This is not thermally affected by the outside differently from hot-dip steel sheet so as to maintain the mechanical property of a material as it is and cause no peeling phenomenon so that there is no quality change by any type of forming and press machining.

페인팅(Painting)
원형판 표면에 아연이 균일하게 부착되어 표면 상태가 균일하고 도료 밀착성이 우수하여 도료에 적합합니다.
Zinc is evenly attached to the circular plate surface so as to have even that surface condition and excellent paint adhering property so that it is suitable for any paint.

내식성(Corrosion resistance)
아연은 모재에 전기적으로 접착되며 고르게 코팅되어 내식성이 우수합니다.
Zinc electrically adheres to the base metal and is coated finely and evenly so as to have excellent corrosion resistance.
용접(Welding)
아연은 부착량이 적고 균일하게 코팅되어 도금 강판 중 용접이 용이하고 전극의 마모가 적습니다.
Zinc has small attachment quantity and is coated evenly so as to be easiest in welding among coated steel sheets and be small in the wear of electrode.
