What is galvanized protection?
There are lower levels of galvanized protection typically referred to as light galvanizing, in-line galvanizing (ILG) or zinc electroplating. In this process, the steel is typically dipped in an electrolyte solution of zinc sulfate. Essentially, this process results in zinc being plated to the surface of the steel.
What is Galvanization?
The truth is, there is a protective coating on the metal – a protective layer of zinc (Zn) has been applied through a process called galvanization. In the simplest terms, the zinc has been applied to the base steel through a process called “Hot Dip Galvanizing” or “Immersion Galvanizing”. The purpose of the zinc immersion is purely for preservation of the steel. Not only does the zinc coating protect the steel by creating a barrier, but it also serves as a sacrificial anode in the event the bare steel is exposed to the environment through a scratch or break in the zinc. Galvanization protects the steel in the same fashion a zinc anode or plate protects the submerged portion of a boat motor – through sacrificial protection.
What is saponification in paint?
Simply stated, saponification is the reaction between the zinc and the fatty acids in the alkyd resin resulting in a soap like substance being formed between the surface and the coating. Over a fairly short period, sometimes weeks, saponification will cause the paint film to delaminate or peel.
What is zinc coating?
The truth is, there is a protective coating on the metal – a protective layer of zinc (Zn) has been applied through a process called galvanization. In the simplest terms, the zinc has been applied to the base steel through a process called “Hot Dip Galvanizing” or “Immersion Galvanizing”.
How is galvanized steel made?
The most common process for galvanizing steel is through the hot dip or immersion method. The fabricated steel will go through a series of steps resulting in a complete coating of heavy zinc. We refer to this kind of galvanizing as batch galvanizing or after-fabrication, heavy duty galvanizing. This process results in the highest level of protection and is commonly specified for highly corrosive interior and exterior environments.
