Galvanized steel production process, standards, applications and pricing

Galvanized steel is a corrosion-resistant material that protects critical surfaces in the industrial and construction sectors. With its variety of sizes and shapes, galvanized steel withstands harsh weather conditions well. Widely used in construction and mechanical manufacturing, galvanized steel plays an important role in contributing to the stable development of many industries.

What is Galvanized Steel?

kho ton ma kem

Galvanized steel, also known as zinc-coated steel or cold-rolled steel with zinc coating, consists of steel sheets covered by a layer of zinc based on hot-dip galvanizing principles. With its shielding function, it provides excellent protection under harsh environmental conditions. It is one of the most popular materials used in the construction and civil industries, such as electrical equipment frames, household appliances, machine casings, etc.

Steps to Produce Galvanized Steel Sheets

According to research, galvanized steel sheets are produced from cold-rolled steel coated with zinc. They undergo four stages as follows:

  • Step 1: The surface is thoroughly cleaned.
  • Step 2: After cleaning, the sheets undergo a NOF annealing process to change the steel’s properties.
  • Step 3: Then, they are coated with zinc using either wet skin pass or hot-dip galvanizing technology.
  • Step 4: In the final step, a layer of chrome or nickel is applied to protect the surface from oxidation.

What are the Standards for Galvanized Steel Sheets?

Galvanized steel products are widely used in practice. There are various types of galvanized steel sheets with the following standards:

Galvanized Steel Coils

First, let’s look at galvanized steel coils. These coils have a smooth, shiny surface with extremely good corrosion resistance. They are applied in the production of processed goods, handicrafts, or rolling. The general technical specifications for this type of steel are:

  • Steel thickness: 0.2 ÷ 3.2mm
  • Steel width: 400mm ÷ 1800mm
  • Inner core steel diameter: 508 ÷ 610mm
  • Maximum steel coil weight: 20 tons

Corrugated Galvanized Steel Sheets

Next, let’s explore corrugated galvanized steel sheets. These are galvanized steel sheets rolled into corrugated patterns, available in various shapes and sizes. The general standards for this type of steel are:

  • Common corrugated zinc thickness: 0.16 ÷ 1.2mm
  • Width of corrugated zinc sheets:
  • 5-square wave corrugated steel sheet: 1.1m
  • 7-square wave corrugated steel sheet: 0.82m
  • 9-square wave corrugated steel sheet: 1.07m
  • 13-square, round wave corrugated steel sheet: 1.10m

Galvanized Steel Sheets

Galvanized steel sheets are steel sheets with an added layer of zinc coating. They have varying zinc thickness per product. These sheets are very hard, making them suitable for making products with high protection and shielding. The hardness of the sheet depends on the type of steel used for galvanization. The general standards for galvanized steel sheets are:

  • Steel thickness: 8mm, 10mm, 12mm, 16mm, 18mm, 20mm, 25mm, 30mm, 40mm, 50mm, 100mm …, 400mm.
  • Steel width: 750mm, 1000mm, 1250mm, 1500mm, 1800mm, 2000mm, 2400mm, 3000mm, 3800mm.
  • Steel length: 6000mm, 7000mm, 8000mm, 10000mm, 11000mm, 12000mm, or custom cut lengths.

Applications of Galvanized Steel Sheets

When it comes to galvanized steel products, their applications are diverse in many fields such as:

  • In construction: Used to manufacture construction roofing sheets, partitions, and water channels.
  • In the electronics and refrigeration industry: Applied in the manufacturing of electronic equipment, computers, washing machines, electrical enclosures, rice cookers, etc.
  • In the mechanical industry: Used to manufacture parts and equipment to protect internal components such as motorcycles, cars, airplanes, etc.
  • In advertising: Used to make signs and billboards. Additionally, they are essential materials in manufacturing roller doors, safes, or other household items.
