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 ele trical 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.
