Galvanized sheet is a steel sheet with a galvanized surface. A layer of zinc is plated on the surface of the steel sheet to improve its corrosion resistance and extend its service life. This treatment method can effectively prevent the steel sheet from rusting in a humid and corrosive environment, and is widely used in many fields such as construction, home appliances, automobiles, packaging, and agriculture.

Galvanized sheet not only has good anti-corrosion properties, but also maintains the strength and toughness of steel. It is easy to process into various shapes and sizes to meet diverse application needs. At the same time, its smooth zinc layer also improves its aesthetics, making galvanized sheet an economical and practical metal material.

Basic information

Main components: iron (content is more than 99%) and zinc (content is less than 1%). Some galvanized sheets may also contain aluminum (such as aluminum-zinc alloy coating).

Specifications and models

Thickness: Usually between 0.4mm and 3.2mm, common specifications include 0.44mm to 0.88mm series.

Width and length: The width range is mostly between 1000mm and 1500mm, and the length can be customized according to demand.

Model: There is no unified abbreviation standard. Common types include hot-dip galvanized steel sheet, alloyed galvanized steel sheet, electro-galvanized steel sheet, etc. The model may contain information such as material, coating type and weight.

Performance characteristics

Corrosion resistance: The zinc layer has strong corrosion resistance and can effectively prevent the steel sheet from being oxidized.

Surface finish: After galvanizing, the surface finish of the steel sheet is high and has good decorative properties.

Fireproof performance: The surface coating of galvanized steel sheet can slow down the spread of flames and improve fireproof performance.

Processing performance: It is easy to perform various processing processes such as bending, stamping, and shearing.

Welding performance: It has strong connection performance with other materials and is suitable for various welding processes.

Application fields

Galvanized sheet is widely used in many fields, including:

Construction industry: used for roofs, balcony panels, window sills, warehouses, rolling doors, etc.

Home appliance industry: the shell and internal parts of household appliances such as refrigerators, washing machines, and air conditioners.

Automobile industry: car roofs, shells, car body panels and other parts.

Furniture industry: the manufacture of furniture such as lampshades, wardrobes, and desks.

Other fields: such as ventilation and heating facilities, musical instrument shells, billboards, photographic equipment, etc.

Production process

The production process of galvanized sheet mainly includes three links: pretreatment, galvanizing process and post-treatment:

Pretreatment: clean the surface of the steel plate from oil, rust and other impurities, and pickle to remove oxides and rust layers.

Galvanizing process: mainly hot-dip galvanizing or electro-galvanizing methods are used to attach a layer of zinc to the surface of the steel plate.

Post-treatment: includes passivation treatment to improve corrosion resistance, oiling treatment to prevent the zinc layer from oxidation and corrosion during storage and transportation, as well as inspection and packaging.
