Hot Dipped Aluminized Steel Sheet & Coil (Ks D3544 Sa1c, Jis G3314)

CHARACTERISTICS


APPLICATIONS




ALCOSTA



Very fine grains due to thesuppression of the growth ofaluminum crystal during solidificationof aluminum melt (5 to 10% siliconcontained)
Uniform surface condition andexcellent corrosion resistanceresulting from the sacrificing effect ofaluminum.
Good appearance after painting

HEAT RESISTANCEThe heat resistance of ALCOSTA is excellent compared to that of zinc-coated steel sheet, galvannealed steel sheet, and cold-rolled steel sheet. Absolutely no changes in appearance and discoloration are observed even under extended exposure to the temperature of 450A C. At temperatures higher than 450A C the coating material transforms to aluminum iron alloy layer so that heat resistance and corrosion resistance are preserved even if discoloration occurs. the coating maintains its sacrificial properties up to the temperature of approximately 600A C.
