HGI (Hot Dip Galvanized Iron & Steel Strip)
is Galvanized Steel strip of HR, that is, HGI is
one of the surface treatments as galvanizing HR
after pickling to prevent iron element from
corrosion. |

The main characteristic of HGI is its
enhancement of the hardness and economical
efficiency by iron¡¯s merits, while avoiding scale
or rust by iron¡¯s demerits. HGI has its best
economical efficiency as it has high corrosion
resistance in spite of long-term usage and it
lasts long period time preventing from
corrosion.
HGI is widely used for
automotive parts and home appliances, customizing
spangle (Zinc¡¯s flower-shaped) and other
specification.
| 1. Corrosion Resistance
: |
HGI shows high corrosion resistance due to
its own electronic chemical protection, physical
protection and atmospheric corrosion
resistance. |
| 2. Formability£º |
Various processing is possible. As HGI has
its excellent adherability and respectively thin
Galvanized-Layer, Galvanized-Layer is not likely
desquamated. |
| ¡Ø |
Yet, its weldability is deteriorated because
Zinc surrounds electrodes. This tends to be
higher as amounts of galvanized-zinc inHGIeases.

If drying of HGI is delayed due to rain or
dew, it may cause white rust. To avoid white
rust, the products should not be piled up one on
another and should be well ventilated indoors.
Yet, the product should be placed not directly
on the ground with no moisture place during
outdoor storage. When raining, wrap it up
completely with protective covers and remove the
covers when the weather becomes clean
again.
¡Ø If possible, avoid unloading when
raining.

Although Zinc is flexible metal and weaker
than iron, galvanized Zinc on the surface is not
likely desquamated. However, if strong shocks
are given, galvanized-layer may be damaged or
desquamated, causing corrosion trouble due to
its exposure.
Therefore, special care is
necessary when handling especially transporting.
For example, try to avoid collision with HGIane
by each acute angle or acute angle to one side.
In addition, consider no deformation caused by
chain and other when moving.

Avoid contact with seawater during ocean
transporting and
storage. | | |
