The purchase price of galvanized sheet pipe+Sales in trade and export
Galvanized sheet pipe and pipe joint are actually the same steel pipe with a surface coated with zinc metal to prevent corrosion and vulnerability and are widely used in the construction industry.

The galvanized coating increases the life of the pipe and also increases its resistance to corrosion and mineral deposits.
Galvanized pipes have long been the most important components of water supply pipes.
These types of pipes are divided into two main categories, galvanized iron, and steel pipes, based on the type and type of metal.
The market is mainly characterized by galvanized iron pipes, which are dark gray in color and made of white rolled iron.
The seams in it are also welded together with a welder and they are then transferred to tanks with molten zinc, in fact they are also called sealed pipes for this very reason.
Galvanized steel
The material of galvanized steel pipe is mild steel, in its structure, the steel plate is passed through a die under pressure, and its seams are welded and then coated (galvanized) in a plating bath to increase its resistance to acid and acid.
Rusted.
There is no fundamental difference between these two kinds of galvanized pipes, but among their differences we can mention the style and shine of galvanized steel pipes compared to iron pipes.
It should also be noted that the acid resistance of galvanized steel pipe is not as good as galvanized iron pipe.
Galvanized pipe is a type of welded pipe.
Typically, galvanized pipe is about 6 feet long, and the diameter of the pipe varies from 1 to 8 inches.
Galvanized pipes are made of white-rolled iron or mild steel.
The main features of this pipeline are:
- Compared to iron pipes, the resistance is small.
- It has high rust and corrosion resistance, so it has a lifespan of more than 50 years.
- It has an integrated construction for increased strength and impact resistance.
- When installed, their color appears transparent, but it can change color after a period of time due to exposure to air, moisture and wear.
- They can be reused and recycled.
- (Galvanized pipe can be melted in a hot furnace and reused to make new products.
- )
Galvanized pipes are mostly used for gas and water transport.
Among the most important applications of galvanized pipes, the following can be mentioned:
- It is often used as water supply pipes in buildings.
- Although its use is not limited to the transfer of liquids, the main part of the gas transfer line is also made of galvanized pipe.
- They are also widely used in irrigation systems.
- They are also widely used for the construction of purification plants and ventilation plants.
Cold galvanized pipe
Galvanized pipes are also divided into two categories according to production method and type of galvanization.
In cold galvanizing, zinc salts are electrolyzed in an aqueous solution to produce products.
These pipes are galvanized and galvanized at low temperatures and covered with a zinc coating.
In this method, the appearance of cold galvanized pipes is shiny and uniform.
Due to the surface of the coating, if deep scratches are made on the surface of these types of pipes, oxidation of the underlying layers may occur; this process reduces the life of galvanized pipes.
In fact, this method of galvanizing pipes does not have much resistance and strength; that is, even if a metal object is dragged on the surface of the pipe, the coating on it will be hit and scratched.
The application of this electroplating method is mainly in industries such as automobile manufacturing, screw, nut, parts manufacturing, and metal coating for health purposes.
This process takes place at a high temperature, iron and zinc metal molecules are involved, and zinc metal penetrates the iron; for this reason, the amount of protection and service life of hot-dip galvanized pipes is greater than that of cold-dip galvanized pipes.
The lifespan of hot-dip galvanized pipes is between 25 and 30 years.
The thickness of the zinc coating in this method is between 40 and 120 microns.
The appearance of the zinc layer in the hot-dip galvanizing method is dull, and gray, and the surface is uneven and not smooth.
This galvanizing method is more suitable for iron products located in the open air.
Such as telecommunication towers, guardrails, high voltage towers, tall and thick water pipes, and telephone poles.
The most important use of galvanized sheets in construction
Galvanized sheet is widely used in building construction.
It should be noted that galvanized sheet is also used in other industries such as automobile manufacturing, urban structure construction, appliances, and military, but this article focuses on the application of this sheet in the construction industry.
Here we discuss four important uses of galvanized sheets in the industry.
Types of corridors in buildings
A building's ventilation system has a high rate of depreciation.
On the other hand, if it is damaged, it is difficult to change the channel.
For this reason, galvanized sheets are used in its construction to ensure that any moisture does not cause this system to rot.
These ventilation systems are:
- Air conditioning
- Types of water and gas coolers
- Fireplace
- Heating pipes
- Engine room chimney
- Air purifier
- Air conditioning
- Junk Shooting System
The appearance of steel channels can be divided into the following three categories:
The difference between these three duct forms is their air transport capacity.
For physical reasons, the circular channel moves air better than the other two.
This is due to the way the air circulates in this channel and its smooth and even surface, which reduces friction.
Of the square and rectangular ducts, the square is more efficient.
For technical reasons, few buildings can use circular galvanized sheet channels.
This option is of course more common in most sheds and large sports fields.

Therefore, square ducts are mostly used in the construction of air transfer ducts.
Using galvanized sheet as a channel in construction is easier to implement and install than otherwise.
Due to its lightweight, easy installation, and high strength, galvanized sheets can be used for roofing of various structures.
Use them, especially in wet weather, to give the roof a sort of waterproof coating.
Galvanized sheets can be used for the construction of the following roofs:
- The villa's pitched roof
- Large and small residential roofs
- Takedown sports and industrial sheds
- gazebo roof
Due to the high color acceptance of galvanized steel sheets, it can be used for gables or pitched roofs on houses, with different colors, which gives it a special aesthetic.
Furthermore, for this purpose, there are various types of galvanized sheets in different shapes and designs on the market, each with its own application.
Why do you think galvanized pipe and sheet is so important in the construction industry? What are the types of galvanized pipes and what does the standard for galvanized pipes mean?
Galvanized pipes are exceptionally resistant to corrosion, mineral deposits and rust.
These pipes are sealed.
This is where the soldering and connections can be seen inside.
These pipes are usually between 1 inch and 8 inches in diameter.
On the other hand, they are about 6 meters long.
These types of pipes have unique properties that we will discuss in more detail.
However, among these properties, wear resistance and a high-strength integrated structure are very important.
Galvanized pipes are made of white-rolled iron or mild steel.
For this reason, in some data, galvanized pipes are divided into two categories by gender, namely:
- Galvanized steel
- Galvanized iron pipe
In addition to this, other types of galvanized pipes are well known among both industrialists and technologists, and their manufacturing method and where they are used is one of the reasons for their name and what distinguishes them from the two categories above.
Galvanized steel
As the name suggests, the material of these pipes is mild steel.
This pipe is made as follows:
- Pass the steel plate through the die
- Welding of plates
- Placing the sheet in a plating bath on top of the coating to galvanize and thus prevent corrosion of the pipe
- Galvanized steel pipes are generally lighter and shinier than other types, but galvanized steel pipes are undoubtedly a bit more expensive.
Galvanized iron pipe
What are the reasons for making galvanized iron pipes? Galvanized pipes are made of white-rolled iron.
This type of pipe is produced in seam form, where the seams are welded using special equipment.
galvanized steel pipe sizes
The pipe is then placed in a tank of molten zinc.
Galvanized iron pipes are gray and dark.
What is a hot-dip galvanized pipe?
In this method, the pipe is placed in a barrel of molten zinc and immersed in it.
In the next step, the tube is heated.
Cold galvanized pipe
During the manufacture of cold galvanized pipes, zinc salts are placed in an electrolytic aqueous solution.
In this production method, the environment has no specific heat.
That is why it is called a cold galvanized pipe.
What is the most basic use of galvanized pipe?
After explaining what galvanized pipe is, it is time to explain the application of this pipe.
Here are some of the main uses for galvanized pipes:
- Heat transfer using galvanized pipes
- gas delivery
- Transport of water and other liquids
Key points about galvanized pipe
These pipes often rust, especially on the inside.
To avoid problems such as broken pipes or unpleasant water smells, such pipes are rarely used for built-in connections.
In households, it is more common to use plastic pipes instead of galvanized pipes.
Price of nail pipe: Pipe is a category of products made of different materials and used in the production of various products and projects, one of the most famous is the nail pipe, which is used in many nailed or welded pipes.
also known as API pipe, is a type of pipe formed by bending steel plates and welded into pipes.
These pipes are welded using different methods, which are of great importance for the resistance and quality of the pipes.
In fact, seam pipes refer to pipes made by pipe forming, forming, and welding steel sheets of different thicknesses and materials.
This type of welded pipe is used in various industries and the price of the welded pipe is applicable.
These applications are as follows:
- Water, oil, gas, and petrochemical transmission lines
- Pier and bridge foundations
- Build pillars, fences, and couches
- Shipbuilding, mines, and tunnels
- Transport of liquids and tank profile products, manufacture of metal products and structures
- Sealed pipes are used to transport gases, water, or other liquids in low or medium-pressure environments.
Zinc metal can be used to increase the life of oiled sheets, iron, and metal profiles.
Using the galvanizing process, this metal is placed as a protective layer on sheets, strips, pipes, etc.
, protecting them from corrosion.
Galvanized pipes are also prepared in the same way.
The zinc metal inside the tube will act as a solid insulator.
This metal prevents contact with liquids or gases from passing through the pipes.
On the other hand, the resistance in the pipes increases, and longer service life has been achieved for constructions with galvanized pipes.
Galvanized iron pipe
The color of galvanized iron pipes is generally gray and dark, and most of them are divided into medium and light colors.
Galvanized pipes are rolled from white iron.
galvanized sheet pipe in the construction industry
Galvanized iron pipe is also called nail pipe, where the seams are connected and welded to each other by means of a device, and then the pipe is dipped in molten zinc metal.
Galvanized steel
Galvanized steel pipe is generally used for ventilation, this galvanized pipe is also used for sewage.
Galvanized steel pipes are made of mild steel, to prepare these pipes, to improve their corrosion resistance and galvanizing ability, and resistance to various acids and rust, they are placed in a bath containing zinc metal until the steel plate becomes galvanized steel plate.
Features of galvanized pipe
The abundance of galvanized pipes in the industry is very high.
Houses are usually made of pipes.
The price of this product is also reasonable and these tubes are very durable.
They are also very popular due to the ability to reuse and recycle these pipes.
The use of galvanized pipe
Galvanized pipes are commonly used to transfer heat, gas, and water.
The formation of rust in steel pipes can lead to contamination of compounds and mixing with bacteria.
In addition, due to the heavy metals in the water, steel pipes are often corroded, causing damage to the human body.
Therefore, the use of this product in the water industry is very important.
