Comparison of the advantages and disadvantages of galvanized iron air duct and FRP air duct

The biggest feature of Ousheng FRP air duct is corrosion resistance and anti-aging, which is also the biggest difference between it and galvanized iron duct, because galvanized iron duct will rust, fracture and embrittlement after long-term use, while FRP air duct will not, and it is light and strong, easy to install, and is a very ideal building!

FRP and phenolic board are composite air ducts, and iron sheets are made of iron air ducts.

**: Iron air duct is the most expensive, followed by composite air duct, and then PVC air duct. (Construction is carried out in accordance with the thickness of the national standard, such as the 1500*450 iron duct should use the national standard millimeter thick iron sheet, if you use the millimeter of course, the cheap one is not like it).

Age: proportional to **, that is, the longest iron sheet (more than 10 years), 5-8 years for the load air duct, and 3-5 years for PVC pipe (mainly depending on the use environment, such as Chinese food, hot pot is short, and hotels and shopping malls are long).

Wind noise and wind resistance (effect): the iron sheet is the best (according to the standard thickness), because the inner wall of the iron sheet is much smoother than the composite air duct and PVC, followed by the composite air duct, and finally PVC (because PVC is a circular pipe, it cannot be done in the reducer part and the iron sheet and the composite reducer part is so long, so the PVC air volume in the reducer part is too large (such as more than 3000 air volume) may produce a short low-frequency whine sound, which cannot be eliminated).

Comprehensive consideration, in the total cost of more than 1.5 million yuan in the use of iron sheets, the following can consider composite air ducts.

If there is any error in the above, please correct it!

Stainless steel air duct is derived from the ventilation duct with professional technology of the duct products, the product not only collects the essence of the technology, more from the actual construction and installation of consumers, for everyone to bring a satisfactory technical operation pointer, the following will share in detail about the characteristics and advantages of the technology.

Introduction to the characteristics of stainless steel air duct:

1. Beautiful appearance, smooth inner wall, low resistance, good air tightness, high compressive strength, can be suitable for very complex exhaust engineering.

2. It can remove flammable and non-flammable chemical corrosive gases, and does not need to install sprinkler fire extinguishing equipment.

3. Made of stainless steel, the material is sturdy and easy to maintain integrity.

Answer: The difference between FRP air duct and galvanized iron air duct mainly lies in the difference in materials and manufacturing processes. The FRP air duct is made of glass fiber reinforced plastic, which has the characteristics of light weight, high strength and anti-corrosion, but the manufacturing process is more complex, so it is relatively high.

The galvanized iron air duct is made of galvanized iron sheet, and the manufacturing process is simple and relatively low.

Explanation: FRP air duct is a kind of air duct commonly used in modern construction, which has better anti-corrosion performance, lighter weight, higher strength and longer service life than the traditional galvanized iron air duct. At the same time, the glass Wuge steel air duct can also be customized according to the needs of the cavity, which is more suitable for various engineering needs.

The galvanized iron air duct is a traditional air duct, which has a simple manufacturing process and low cost, but is easy to rust and wear, and has a relatively short service life.

Expansion: In addition to FRP air ducts and galvanized iron air ducts, there are also air ducts of different materials, such as aluminum alloy air ducts, stainless steel air ducts, etc. These air duct materials have their own characteristics, and can be selected according to the actual needs of the project.

At the same time, the air duct will also vary according to the material, manufacturing process, specifications and other factors. In the construction project, it is necessary to select the appropriate air duct material and specification size according to the actual situation to ensure the quality and safety of the project.

The difference between FRP air duct and galvanized iron air duct** mainly depends on the following aspects:

1.Material cost: Compared with the remaining burial, the raw material cost of FRP air duct is usually higher than that of galvanized iron air duct. FRP is a composite material, which is composed of resin and glass fiber vertical bush antwei, which needs to be made by a special production process, so the relative cost is high.

2.Production process: The production process of FRP air duct is relatively demanding, and it requires multiple processes such as mold design, manual coating, and curing, so the production cost is relatively high, which will also affect the product.

3.Service life: In comparison, the service life of FRP air duct is longer, generally more than 20 years, while the service life of galvanized iron air duct is shorter, about 10 years. This is also a major reason for the difference between the two.

4.Market demand: Different regions and markets have different needs for air ducts, which may lead to gaps in the air duct. For example, the demand for FRP products is higher in some regions, resulting in relatively high product **.

On the whole, Zhengkong, the ** of FRP air duct is generally higher than that of galvanized iron duct, but FRP air duct has better performance in terms of service life and corrosion resistance, and has a better cost performance relatively speaking. It is necessary to choose the right product according to the actual needs.

Compared with the galvanized iron air duct, the FRP air duct is more expensive, the main reasons are as follows: first, the material of the FRP air duct is mainly resin, glass fiber and other composite materials, and the production needs to be coated with multi-layer film, artificial weaving and other complex processes, while the galvanized iron air duct is made of zinc plate as raw material, and the production process is relatively simple, so the production cost of FRP air duct is higher. Second, FRP air duct has better heat insulation, anti-corrosion and other properties, relatively higher quality, longer service life, so it is higher.

Third, the production and installation of FRP air ducts require certain professional skills and experience, and the labor costs of workers are correspondingly higher. In general, the higher FRP air duct** is mainly due to the difference in materials and processes, but its performance and quality are relatively better, and the service life is longer.

The difference between FRP air duct and galvanized iron air duct** mainly depends on the following factors:

1.Material cost: FRP air duct is made of composite materials such as glass fiber and epoxy resin, while galvanized iron air duct is made of steel plate galvanized.

Therefore, there is a big difference in the cost of raw materials between the same specification FRP air duct and the galvanized iron sheet air duct, the latter is usually cheaper.

2.Manufacturing process: The manufacturing process of FRP air duct requires multiple processes such as mold manufacturing, surface layer laying, and curing, which is more complex and has low productivity; The galvanized iron air duct can be quickly processed through machining, buckle welding, etc., and the productivity is high.

3.Service life and performance: Although FRP air duct has certain advantages in performance, such as flame retardant, corrosion resistance, easy processing, etc., its service life is relatively short, generally about 10 years; The galvanized iron air duct has high durability and the service life is generally more than 20 years.

To sum up, the difference between the FRP air duct and the galvanized iron air duct mainly depends on the difference in material cost and manufacturing process, and there are also differences in service life and performance. When purchasing, you should choose according to your actual needs, and it is recommended to do market research before purchasing.

There are two main differences between FRP air ducts and galvanized iron air ducts: 1Material Costs:

The FRP air duct uses glass fiber reinforced material to roll the nucleus, while the galvanized iron duct uses metal iron sheet material, so the material cost will be higher than that of the galvanized iron duct. 2.Product Performance:

The FRP air duct has good corrosion resistance and can withstand the erosion of corrosive media such as acid and alkali, while the galvanized iron air duct is relatively wide. In addition, the FRP air duct can also withstand certain temperature changes, has high compressive strength, and has a long grinding service life and maintenance cycle. Therefore, the FRP air duct is relatively high, but it is more stable in use, more environmentally friendly, and more convenient to maintain.

The galvanized iron air duct is relatively cheap, but it is also relatively easy to corrode and wear, and the service life is relatively short.

Generally speaking, the ** of the glass steel air duct will be more expensive than the galvanized iron air duct. Because the glass steel air duct has better corrosion resistance, higher sealing performance, lighter, more durable and other characteristics. The cost of galvanized iron duct is lower and easier to process, but it is easy to get damp, rust, collapse bridge shape and other problems, and the fire performance is poor, and the measures of the safety square group are required to resist the fierce surface, so it is relatively low.

However, the specific ** still needs to be evaluated according to factors such as material quality, design specifications, and quantity.

FRP air duct and galvanized iron duct are two commonly used air duct materials for ventilation and air conditioning systems, and their differences are mainly affected by the following factors:

1.The main raw materials of FRP air duct are glass fiber and resin, while the main raw material of galvanized iron air duct is steel plate, so the cost of FRP air duct is higher than that of galvanized iron air duct.

2.The manufacturing process is different: the FRP air duct needs to adopt a complex molding process, and it needs to be made by hand, and the processing is difficult, so the manufacturing cost is relatively high. The galvanized iron duct processing technology is relatively simple, and the manufacturing cost is relatively low.

3.The service life is different: the anti-corrosion and anti-aging performance of the FRP air duct is good, and the service life can reach more than 20 years, while the galvanized iron air duct is easy to rust and wear, and the service life is generally about 10 years.

Therefore, the service life of the FRP air duct is longer, but its ** will be correspondingly higher than that of the galvanized iron air duct.

To sum up, FRP air duct** is higher than galvanized iron duct, but due to its excellent performance, it can reduce maintenance and replacement costs in long-term use. It is recommended to choose the appropriate air duct material according to the actual needs and budget.

FRP air duct is a little higher than the galvanized iron air duct, if the diameter is about 30cm FRP air duct, then its crack market price is 75 yuan per square meter. If the diameter size is about 10cm of cable fiberglass, then its market is 30 yuan per square meter of high fiber.

FRP air duct and galvanized iron air duct are commonly used air duct materials in industrial ventilation systems, and their differences lie in the material and service life. FRP air duct is made of composite materials such as glass fiber reinforced materials and epoxy resin, which has the advantages of lightweight, corrosion resistance, insulation, heat insulation, etc., and is suitable for occasions with large acidity and alkalinity, which is relatively high. The galvanized iron duct is made of hot-dip galvanized iron sheet, which has the advantages of strong durability and relatively cheap price, and is suitable for general occasions.

In general, FRP air ducts have better performance and longer service life than galvanized iron air ducts, but they are also relatively high. When purchasing air ducts, it is necessary to choose the appropriate materials according to the actual use environment and requirements.

Answer: There is a big difference between the FRP air duct and the galvanized iron air duct. The ** of FRP air duct is relatively high, usually about 50%-100% more expensive than galvanized iron air duct.

Explanation: First of all, the production process and materials of FRP air duct are relatively special, and special composite materials and molds need to be used to make them, so their production cost is relatively high. Secondly, the FRP air duct has excellent performance, just like the characteristics of anti-corrosion, acid and alkali resistance, light weight, high strength, etc., so its service life is longer than that of galvanized iron air duct, and the maintenance cost of dust is low, so it is relatively high.

Expansion: In addition to **, there are other differences between FRP air duct and galvanized iron air duct. For example, FRP Fengyan Zen Road is more suitable for use in humid and corrosive environments than galvanized iron air ducts, while galvanized iron air ducts are more suitable for use in general environments.

In addition, the installation of FRP air duct is relatively complex and requires professional technicians to operate, while the galvanized iron air duct is relatively simple and can be installed by ordinary workers. Therefore, when choosing an air duct, you need to choose according to your actual needs and budget.

There will be certain differences between FRP air duct and galvanized iron air duct. The ** of FRP air duct is generally higher than that of galvanized iron air duct, this is because FRP air duct has the following advantages:

1.FRP air duct and galvanized iron air duct are two commonly used materials in ventilation and air conditioning systems, and their differences are mainly affected by the following aspects:

1.Material cost: The cost of raw materials for FRP air ducts is relatively high, while the cost of raw materials for galvanized iron ducts is relatively low, so the cost of FRP air ducts is also relatively high.

2.Production difficulty: FRP air duct production is difficult, requiring complex mold production and hand-made production, while the production of galvanized iron air duct is relatively simple, so the production cost is relatively low.

3.Different uses: FRP air duct is suitable for high-demand places, such as food processing plants, hospital operating rooms, etc., while galvanized iron air duct is suitable for general ventilation and air conditioning systems, so the ** of FRP air duct is also relatively high.

In general, the ** of the FRP air duct is higher than the ** high grip of the galvanized iron air duct, but it also depends on the actual situation, such as the size, thickness, quantity, difficulty of production, use, etc.
