1. What is Galvanized Steel

Galvanized steel is a type of steel coated with an outer layer of zinc to prevent the formation of rust, oxidation, and environmental influences (climate, temperature, humidity, ...).

Galvanized steel is divided into hot-dip galvanizing and electroplating with different characteristics and pros and cons:

Hot-dipped galvanized steel pipe

Hot-dip galvanizing is the traditional method of coating steel pipes with a protective layer. Surface-treated steel pipes are dipped into a tank of molten zinc. The zinc layer is evenly coated on both sides, with good rust resistance, adhesion, and long life expectancy. GI's zinc coating is usually about 50 micrometers thick on average.

Electrolytic Galvanized Steel Pipe

Electrolytic galvanizing, also known as cold galvanizing, only uses a minimal amount of zinc, about 10-50g/m2, to coat the outer surface of various products. Electrolytic plating technology creates a precipitate on the metal layer, so the corrosion resistance is much worse than that of hot-dip galvanized steel. Products cold-plated have low cost, high adhesion, and low deformation at high temperatures.

&#;ng tôn m&#; k&#;m là gì?What are galvanized steel pipes?

Galvanized steel pipes are steel pipes that have undergone a specialized coating process to resist corrosion and increase the lifespan of the pipes. These pipes are typically made of carbon steel and coated with a layer of zinc, creating a protective barrier between the steel and the surrounding environment. The zinc coating not only provides exceptional rust and corrosion resistance but also enhances the overall durability of the pipes.

Manufacturing process

The manufacturing process of galvanized steel pipes involves several steps to ensure the final product is durable and reliable. Here is a brief overview of the process:

• Cleaning: The steel pipes are thoroughly cleaned to remove any impurities or dirt, ensuring proper adhesion of the zinc coating.
• Pickling: Subsequently, the pipes are immersed in an acid solution to remove mill scale or oxides present on the surface. This step further prepares the steel for the electroplating process.
• Galvanizing: The cleaned pipes are then immersed in a molten zinc bath. Through a metallurgical reaction called hot-dip galvanizing, zinc forms a tightly bonded coating on the surface of the steel.
• Cooling and inspection: After galvanizing, the pipes are cooled and inspected to control quality. This step ensures a uniform zinc coating with no defects.
