Fe-Zn Galvannealed Steel Sheet(GA)

합금화 용융아연도금강판(GA : Fe-Zn Galvannealed Steel Sheet)

용융아연도금강판은 간단한 전처리 과정을 거쳐 용접성과 도장 성이 크게 향상됩니다. 코팅 공정 후 특수 열처리는 아연 도금 층과 금속베이스 사이에 합금 층을 형성합니다.
Galvannealed steel sheet offers significantimprovements in weldability and paintability byundergoing a simple pre-treatment process. Afterthe coating process a special heat treatment formsan alloy layer between the galvanized layer andthe metal base.

우수한 용접성(Superior weldability)

아연 도금 된 시트의 용접성은 용접 전극에 아연 코팅이 흡수되기 때문에 크게 손상됩니다. Galvannealed plate는 표면의 FeZn 합금의 높은 융점으로 인해 용접성이 크게 향상되어 전극 오염을 방지합니다.
The weldabilityof galvanized sheet is drastically compromisedbecause of the absorption of zinc coating onto thewelding electrode. Galvannealed plates havesignificantly improved weldability because of thehigh melting point of FeZn alloy on the surface,which prevents electrode contamination.

박리 저항성(Greater peeling resistance)

우수한 박리 저항성 합금 층 형성으로 인한 탁월한 도료 접착력으로 일반 용융 시트에 비해 굽힘 및 접힘 처리시 박리 저항성이 크게 향상됩니다.
Due toexceptional paint adhesiveness resulting from theformation of alloy layers, the peeling resistanceduring the bending and folding treatment isgreatly enhanced, compared to regular hot-dippedsheet.

우수한 도료 접착 성 및 내식성(Superior paint adhesiveness and corrosionresistance)

아연 도금 된 시트 표면의 거친 합금 층은 전처리 (인산염 및 크롬 산염 처리)에 대한 반응을 촉진하여 도료 접착 성과 내식성을 향상시킵니다.
The rough alloy layers of thegalvannealed sheet surface facilitates thereaction to the pre-treatment (phosphate andchromate treatment), improving paint adhesivenessand corrosion resistance.
