Product Introduction

Galvanized steel is a special steel material, and its manufacturing process involves the ordinary carbon construction steel to be galvanized. This treatment can effectively prevent steel corrosion and rust, thus extending the service life of steel. Galvanizing methods are mainly divided into electric galvanizing and hot dip galvanizing.

Does galvanized steel rust? It will not rust under normal conditions. It was designed to keep steel from rusting. By plating a layer of zinc on the surface of steel, a dense zinc oxide film can be formed to effectively isolate the contact between steel and oxygen, moisture and other corrosive media in the air, so as to achieve the purpose of rust prevention and corrosion prevention. This zinc layer protects the steel from corrosion and extends its service life.
However, it should be noted that if the galvanizing layer is damaged (such as scratches, wear, etc.), the steel has the potential to be exposed and thus rust. In addition, if the steel is in harsh environmental conditions for a long time (such as high temperature, high humidity, strong corrosive gas, etc.), it may also lead to accelerated corrosion of zinc layer, thus affecting its rust prevention performance.

Feature
Advantageous Features
Strong corrosion resistance
Under the protection of zinc layer, galvanized steel has strong corrosion resistance. The zinc layer can effectively prevent oxygen, moisture and other corrosive substances in the air from coming into direct contact with the steel substrate, thus greatly extending the service life of the steel. In addition, it also has good weather resistance and can maintain stable performance in a variety of harsh environments.
High surface finish
Its surface is specially treated and has a high finish. This makes this steel has high requirements in terms of aesthetics, and can meet various decorative and appearance needs. At the same time, the smooth surface is also easy to clean and maintain, reducing the cost of use.
Excellent fire performance
It is not easy to burn at high temperatures and has excellent fire resistance. In the event of a fire, galvanized steel pipe can effectively prevent the spread of the fire and protect the safety of buildings and personnel. Therefore, it is particularly widely used in the field of construction, especially in places with high fire protection requirements.
Good processing performance
It has good processing properties and can be processed by cutting, bending, stamping and other processes. This allows this kind of steel to meet the needs of a variety of complex shapes and structures, convenient design and production.
Excellent welding performance
It can be connected by a variety of welding methods. The welded steel joint is solid and reliable, and can meet various requirements. This makes it a unique advantage in the application of large structures, pipelines, Bridges and other fields.
Good plasticity and toughness
Galvanized steel has good plasticity and toughness, and can be deformed to a certain extent without breaking when subjected to external force. This makes it have high safety performance when bearing complex loads such as shock and vibration.
Process
Product Process
01
Surface treatment
Before the galvanized treatment, the steel material needs to be surface treated to clean and remove the surface oxide layer and impurities, to ensure that the zinc layer can be firmly attached to the steel surface. This step usually includes methods such as pickling, alkali washing, or mechanical treatment. Alkali washing involves soaking steel in lye containing sodium hydroxide or potassium hydroxide to remove grease and other organic contaminants from the surface.
02
Degreasing
For the parts containing paint and grease to be plated, degreasing needs to be deoiled.
03
Washing
The degreased parts to be plated are washed so that their PH value is below 10, in order to facilitate the next stage of rust removal operation.
04
Pickling and rust removal
Pickling of iron and steel materials to further remove surface rust and impurities. During pickling, it is necessary to frequently turn the parts to be plated, and strictly control the pickling time to avoid soaking the material in acid for a long time.
05
Galvanizing treatment
According to the selected galvanizing method (electric galvanizing or hot dip galvanizing), the steel material is galvanized. Electrogalvanizing is to form a layer of zinc on the surface of the steel by electrolysis, while hot dip galvanizing is to immerse the steel material in the molten zinc liquid, so that zinc reacts with the surface of the steel and forms a layer of zinc-iron alloy.
06
Follow-up treatment
After the completion of galvanizing, it may also be necessary to carry out follow-up treatment such as light, passivation, washing and drying to improve the performance and appearance quality of the galvanizing layer.
