Characteristics :

GL are 3 ~ 6 times more corrosion - resistant compared to GI , but has a similar level of processability and weldability and can replace GI, and in particular is most suitable when replacing GI that require thick galvanized layers and high corrosion resistance .

Only galvanized steel sheet that is used for roofing and walls without painting because of its unique silver spangles and beautiful appearance and high - corrosion resistance, and is used as a cool roofing material because of its excellent heat reflection qualities .

Can replace aluminum gilded steel sheets because for certain purposes of its electrical conductivity and its heat-resistance qualities even at high temperatures that do not exceed 315 ℃ .

Has greater surface hardness than GIs , and is much more wear - resistant .

Corrosion resistance increased more with resin-coating treatment , which enables roll forming or press forming without the spraying of processed oils .
