PAINT
GRIP & GALVANIZED PAINTABILITY
|
|
There
are several terms used for paintable galvanized steel.
Listed below are some:
- Acid
Washed
- Paint
Grip
- Phosphate
Treated
- Galvannealed
- Electro
Galvanized
|
|
The
excellent corrosion resistance that results when the alloyed steel
coating is painted is useful when the application demands a long
service life.
Acid
washed and paint grip are one in the same.
Paint grip has become a generic term used by both suppliers,
equipment manufacturers, contractors and the design team.
Galvannealed
sheet is an ideal material for painting.
Galvannealed sheets can be readily painted.
Typically, the surface should be cleaned so the application of
a suitable primer and topcoat can achieve good paint adhesion and
corrosion resistance.

Phosphatized
Any
galvanized sheet surface finish can be “phosphatized”.
This product is specially pre-treated at the steel mill for
subsequent painting.
The treatment produces a crystalline deposit of hydrated zinc
phosphate compounds onto the galvanized surface. The phosphate
coating provides a good adherent base for the application of paint.
Minor cleaning may be necessary to remove oils or soil picked
up during fabrication, shipping and/or handling. |
|
Painting
Many
types of paint can be used on galvanized sheeting.
The paint choice depends upon the results required by the
design team.
For example, some design teams will maximize weather
resistance, while others will provide a new gloss finish for
aesthetics.
Consultation with the paint supplier is recommended to obtain
the desired results. |
