Reasons to Choose Galvanized Steel Pipe

To understand the reasons you would need a galvanized steel pipe, you should first ask what is galvanization? Galvanization is the process of adding a protective coating made of zinc to iron or steel to help prevent rusting. With this layer of protection pipes can be used in outdoor areas, and can withstand the harm from some of the environmental effects. Galvanized steel pipe is used in many outdoor applications such as fencing, fence posts and water-supply pipes.

Galvanized Steel Pipe Process

The main process for galvanizing a pipe is the hot-dip galvanizing. This is where you take the steel pipe and dip it in a bath of liquid zinc. The coating is made by a metallurgical reaction between the iron in the steel and the liquid zinc. This process was started in and provides corrosion protection for pipes at a reasonable cost. The steps for hot-dipping are first to use caustic cleaning, then rinse, next would be the pickling, followed by another rinse. After the rinse, the metal is dipped into flux solution then taken out to dry. Next would be the zinc bath, followed by cooling and inspection.

Benefits of Galvanized Steel Pipes

By using a galvanized pipe, you can avoid the cost of maintaining and replacing corroded pipes. With galvanized pipe, your pipes can last a lot longer than a non galvanized one, which will save you money.

What is galvanized steel pipe used for? Let's explore these applications in agriculture, solar energy, oil industry, construction and more with MRS Steel!

Galvanized steel pipe has been coated with zinc to protect the steel from corrosion. GI is most commonly used for outdoor construction such as fencing, handrails and interior plumbing applications (plumbing, fire fighting systems,…). MRS Steel will dive deeper into the issue of “what is galvanized steel pipe used for”.

What is galvanized steel pipe

Galvanized steel pipes are hollow, thin-walled steel structures with good load-bearing capacity and minimal impact from environmental factors. The addition of an external zinc coating further enhances their resistance to rust formation, oxidation and environmental influences such as 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 very small 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.

Galvanized steel pipes offer strength, rust resistance and versatility for construction needs

Galvanized steel pipe classification

• Round steel pipes: mainly used for water pipes, lamp posts, railings, stair handrails, ultrasonic piles,...
• Square and rectangular steel pipe: depending on the thickness of the steel pipe, it will be used as a roof frame, scaffolding or in the manufacture of furniture, motor vehicle parts, ...
• Oval steel pipe: this type of galvanized steel pipe is widely used in the field of furniture, frames’s car, motorcycles, bicycles,...

What is galvanized steel pipe used for?

Galvanized steel pipes have many outstanding features such as high aesthetics, comprehensive protection, good life expectancy, ... when applied to projects and fields of life.

Applications in solar energy

Solar panels have a large mass of 20-24kg to ensure that the system is not affected by the effects of storms or high winds. Therefore, the support frame needs to be strong, capable of withstanding large loads and wind levels of 10, level 12 in stormy weather. In addition, the frames that support the solar system are placed outside and are often affected by the weather, so they must resist corrosion.

In almost all materials, galvanized steel can meet all of the above requirements thanks to its stable, solid, high-strength, load-bearing and good-bearing structure. The zinc coating on the outside of the steel pipes has a comprehensive protection effect, increasing the long term use of the frame system. Therefore, galvanized steel, especially pipe steel, box steel, V-shaped steel,..., are often chosen as frames for solar power systems.

Application in agriculture

Galvanized steel pipe has good rust resistance, variety of sizes, easy to shape and install, so it is widely used in irrigation systems.

Black steel pipes, hot-dip galvanized steel pipes are also widely used in animal husbandry. Large steel pipes are used to make feed or waste pipes for livestock and poultry.

In the fishery, fish farming cages are made from hot-dip galvanized steel pipes, replacing bamboo cages, overcoming limitations in rust resistance, life expectancy and cage breakage when there are large underground waves.

Galvanized steel pipes offer versatility and durability for agriculture

Applications in plumbing

Steel pipes are widely utilized in water supply and drainage systems, high pressure plumbing installations or outdoor water supply networks. The nature of these projects all need large load capacity, easy to bend, shape according to the terrain, installation location, so galvanized steel pipe is the most appropriate option.

In addition, square or rectangular galvanized steel pipes are also used for ventilation systems, assembling house frames, scaffolding, bearing trusses,...

Galvanized steel pipes are ideal for water systems and structural applications

Applications in telecommunications

The telecommunications system is the basic of social communication. Many telecommunications forms are utilized galvanized steel pipes to product public lighting, ultrasonic pile systems, broadcasting piles, telecommunications poles, wiring, equipment boxes,...

Application in construction

The application of galvanized steel pipes in the construction field must be mentioned as the key materials for housing and civil works such as rails, gutters, fences,... These steel pipes are shiny galvanized, aesthetics and durability, suitable for outdoor applications.

Galvanized steel pipes are durable and aesthetic for housing and civil works
