Electro Galvanizing |
Hot Dip Galvanizing |
Mechanical Galvanizing |
Plating
process |
Hydrogen embrittlement
occurs
There are
portions that have not
been plated |
Assembly of screw is difficult
due to large amount of zinc
adhering to the thread of
screw in the plating procedure.
Hydrogen embrittlement does
not occur |
Does not tangle up and
rusting does not occur.
No occurrence of hydrogen
embrittlement |
Hydrogen
embrittlement |
Cannot eliminateeconomic
loss and injuries to people
due to accidents caused
by hydrogen embrittlement |
|
Absence of safety accidents
and injuries to people due
to hydrogen embrittlement.
Assured economic profit
|
Uniformity |
Cannot expect to
achieve
uniformity as there are
differences for each
section |
Cannot expect to achieve
uniformity as there are
differences in thickness for
each component and cannot
be measured |
Uniformed plated on each
section. Easy to control
and
measure thickness of
plating. |
Prevention
of corrosion |
Very low resistance |
Relatively outstanding but
does not measure up to
mechanical plating |
Superior to hot dip
galvanizing according to
salt water spray test |
