Product Description

Introduction to hot-dip galvanizing process

1. Basic principle: The steel Lamp Post that has undergone strict pre-treatment (degreasing, acid washing, and plating assistance) is immersed in molten zinc solution (usually around 450 ° C) to undergo metallurgical reactions on its surface, forming a layer of iron zinc alloy and pure zinc layer.

2. Difference from cold galvanizing (electroplating):

Different processes: Hot dip galvanizing involves a physical and chemical reaction (immersion in molten zinc), while cold dip galvanizing involves an electrochemical reaction (electrolytic deposition).

Zinc layer thickness: Hot dip galvanized zinc layer is much thicker (usually above 65-85 microns, or even thicker), while cold dip galvanized zinc layer is thinner (usually 5-25 microns).

Adhesion: The alloy layer formed by hot-dip galvanizing has a strong bonding force with the base metal and is not easily peeled off; Cold galvanizing has relatively weak adhesion.

Corrosion resistance life: The corrosion resistance life of hot-dip galvanizing is much longer than that of cold galvanizing, usually up to 20 years or more (under standard atmospheric conditions).

Appearance: The hot-dip galvanized surface has zinc flowers (which can be treated as zinc free), slightly rough; Cold galvanized surface is smoother and more uniform.

Cost: The initial cost of hot-dip galvanizing is usually higher than that of cold galvanizing, but the long-term maintenance cost is much lower than that of cold galvanizing and painting.

Production of Steel street light Pole

Light Poles production process

Steel plate leveling---rod winding---welding--- grinding and straightening--- hot galvanizing---grinding and straightening---plastic spraying and packaging.

The process of all bars is like this. Let's take the street lamp bar as an example to introduce it emphatically.
