Reading time: 12 minutes
Galvanized mesh netting, a type of wire productIt is considered to be designed and produced in the form of a mesh. This mesh has many functions and benefits in the construction industry. This mesh is produced and produced in various sizes and shapes. Galvanized mesh has wide applications in various industries. For this reason, we decided to explain in this article from Iron Online, types of mesh and galvanized mesh, history, applications, etc. and discuss the basic points of this type of mesh. .
What is mesh netting?
Mesh netting or “Welded wire mesh” It is a type of wire mesh that has a wide range of applications in all fields. Manufacturers make mesh nets by connecting steel bars together. These nets are like warp and weft with a ninety-degree angle, and to form this angle, vertical bars must be placed on horizontal bars. After carefully aligning the bars, they are welded at the intersection using the spot welding method. .
After experimenting with various methods, manufacturers found that this method of making mesh nets has more advantages than others; because in this case, the mesh nets will show considerable strength and durability. In fact, the high strength of the nets prevents them from constantly shaking and sagging when used in different areas. In general, mesh nets are barriers made of metal threads, fibers and flexible and malleable materials that look like a network of connected threads. .
Mesh nets are made of black iron and galvanized wires. To use them in different applications, mesh nets are offered in the market in three forms: panel, steel and ribbed. They are several times more resistant than wire mesh in different conditions. Now, there is a type of mesh net that we call galvanized mesh, and we will examine it further. .
History of the use of mesh netting in industry
Mesh netting in English is called “welded wire mesh” It is also known as this series of structural equipment. Also known as “Engineering Mesh”, its acronym is “BRC MESH”. This product was first used in a city in England in 1880. Gradually, with the great progress made in various professions, engineers produced and marketed mesh netting in various materials and shapes. Today, this product is considered the basis of industrial work to provide the best performance. One of the reasons for writing this article about galvanized mesh is its high advantages and benefits. .
Galvanized mesh
How many parts are mesh nets divided into based on material?
In general, mesh nets are divided into two types: simple pre-welded mesh nets and ivory welded mesh nets. These nets are also classified as ivory, panel and steel mesh nets. The material of all these mesh net categories is black iron or galvanized wire, which is produced using the appropriate material based on the type of quality and application they require. .
برای مثال، استحکام و دوام مشهایی از جنس گالوانیزه خیلی بالاتر از مشهای آهنی است و هنگامی که مشتریان محصولی با مقاومت بالا میخواهند، تولیدکنندگان در ساخت توری مش فلزی, use galvanized wire (galvanized mesh). It is clear that the equipment designer must also consider the application of the wires to determine their thickness. .
With the information and request that the customer provides to the designer, the appropriate thickness for the wire is considered. Due to the wide use of mesh nets as structural materials such as load-bearing walls, ceilings and partitions, many details must be used in its construction. .
Galvanized mesh net production dimensions
The widespread use of galvanized mesh in the construction industry has provided a compelling reason for its high sales in the market. For example, two of the best-selling mesh sizes on the market are the 6-gauge rebar size with all available springs and the 8-gauge with springs of 10×10, 15×15 and 20×20. .
It is interesting to know that the dimensions of the mesh are expressed based on the thickness of the rebar and the size of the spring. Each sheet of galvanized mesh is made according to a standard size, the most widely used standard defined for their manufacture is 1 x 2. Manufacturers can also make galvanized mesh netting in different sizes according to the needs and requests of customers. .
Grades 6 to 16 are the grades of rebar used in the production of mesh netting; with this wide range of rebar grades, manufacturers can create a lot of variety in the manufacture of this product. The defined size of 20*20 means that the rebars are spaced 20 centimeters apart. In fact, with this distance, square or rectangular springs with dimensions of 5 to 40 centimeters can be created. .
In general, the length of mesh networks ranges from 1 to 9 meters and their width is defined between 100 and 250 centimeters. Usually, galvanized mesh net manufacturers, to satisfy customers in large projects, prepare and produce mesh nets based on the dimensions that the customer wants. .
Galvanized mesh weight
In determining the weight of galvanized mesh in the dimensions of one square meter, factors such as the geometric texture created in the mesh network, the type of rebars used, the distance between the rebars and the sizes of the mesh sheets have a significant impact. As a result, we examine the minimum and maximum weight of galvanized mesh for you. .
- The lowest weight of galvanized mesh
The lowest standard weight for galvanized mesh nets is a mesh made using grade 6 rebar and 30×30 springs, in which case the weight of the mesh per square meter reaches 1.5 kilograms.
- Maximum weight of galvanized mesh
The highest weight is for galvanized mesh netting, which is produced in the dimensions of 12-gauge plain or ribbed rebar and 10×10 springs, which has a weight equivalent to 18 kilograms per square meter. As a result, it can be said that the weight of mesh netting will vary between 1.5 and 18 kilograms. .
Points to consider when implementing galvanized mesh
Of course, there are many things to consider when installing and dismantling metal parts. By paying attention to these points when installing galvanized mesh, you will both do your job in the best way and you or someone else will not be injured while doing the work. These things that we must observe when installing galvanized mesh are: :
- Cleaning up pollution
Before you start working with the nets, thoroughly clean the rebars you will be using from any dirt or sticky material left on them. This will help you to avoid any problems during the installation process. Welding rebar and connecting them to concrete materials should not be a problem and they can be easily connected.
- Maintaining order
Nothing is done well without order. So to get better performance, do the work in an orderly and uniform manner. You should also match the welding steps with the tools you have previously determined for them. .
- Sufficient accuracy
When working with and installing rebar, use extreme care to minimize the possibility of the rebar welds breaking or separating.
- Avoid using rusty rebar.
Never use rusty rebar for your projects. If you use rusty rebar for your project, it will cause you to incur a lot of costs and damages in the future. Also, in addition to the poor performance it provides, your work history in this profession will be questioned and this will have bad consequences for both you and the company you work for. .
- Maintaining temperature balance
To increase the resistance of the manufactured meshes, try to keep the wires as warm and cool as possible while making these galvanized meshes. By observing this point, in addition to multiplying the resistance of the galvanized mesh, it also increases the durability of the concrete materials. .
- Avoid humid weather.
The last thing you should consider is keeping the rebar away from humid air. Between the two types of iron and galvanized wire, using galvanized wire will be preferable to iron. .
Applications of galvanized mesh in various industries
Types of mesh nettingIt has a wide range of applications in various industries, but among them, its use in the construction industry has attracted the most attention from customers. Galvanized mesh netting is available in various sizes and is used in prefabricated concrete structures, wall and roof foundations, creating barriers for warehouses and factories, and fencing. .
One of the interesting applications of galvanized mesh in other industries is its use in the construction of composite roofs for subway channels. It also plays an important role in the bridge construction industry and water supply channels. When engineers want to determine the strength of concrete surfaces and foundations, they use galvanized mesh rebar networks with rebars of 2×6 dimensions or their desired dimensions. .
Apart from galvanized mesh, various types of mesh netting are used in large and small industries such as agriculture, horticulture, transportation, fencing of places for security, mines and even home decoration. Another area where the use of mesh netting plays a fundamental role is the construction of large structures. Now we will examine one of the most important industries, namely the construction industry, and the use of galvanized mesh in it in detail for you. :
Application of galvanized mesh in various industries
Galvanized mesh applications in the construction industry
As we said in the previous sections, the use of galvanized mesh in the construction industry is more noticeable than in other industries. Knowing this, we preferred to explain more clearly about their use in the construction industry and say what type of galvanized mesh we should use in each situation. So we will examine two important cases of its use in the construction industry. :
- Using galvanized mesh in shear walls
In the construction of structures, a strong force is applied to them, which is called shear force. Structural designers use shear walls to reduce this force. After coming up with this idea, they also encountered some problems. One of these problems was that when using shear walls, the areas near them would experience disturbances during concrete pouring due to the need for more rebar. To solve this problem, they used a large number of galvanized mesh nets throughout it and reduced their distance compared to before. In some cases, it is possible to use mesh nets with a higher rebar grade to solve this problem. .
- Using galvanized mesh in beams
Structural engineers consider the beam as the main component of the structure. These beams must bear the highest tensile load in the structure. As a result, it was decided to use galvanized mesh netting to increase their tensile strength along with tension bars. If the bending moment of the beam is greater than the balanced limit, the use of mesh netting will play a useful role in improving its condition. .
When using galvanized mesh in the ceiling of the block joist, pay attention to the ribbed type with a shorter length than the joist so that it fits better inside the heel concrete. In addition, you should pay attention to the arrangement of the rebars and their distance from each other. Engineers believe that the diameter of the mesh mesh rebars and their height will be very effective in the arrangement of the structures. .
Advantages of using galvanized mesh netting and other types of mesh netting
After reading all these uses of galvanized mesh, you must have realized that its many advantages have made it one of the most widely used structural equipment. One of the factors that has made galvanized mesh stand out from other products is the high speed of wire placement. .
Other benefits include:
- Facilitation of tran sportation
- Saving on materials
- Cheap price and reduced installation costs
- Light weight
- Time saving
- Due to spot welding and regularity of the force nodes, galvanized mesh netting provides the customer with high resistance.
Factors affecting the price of galvanized mesh
Due to the great variety in the production of galvanized mesh, they determine different rates in the market, considering their dimensions and weight. Also, the raw materials of the meshes are iron and galvanized, the prices of which may change constantly according to global consumption. Despite these factors, it is not possible to determine an exact price for them, but there are also factors that affect the price of galvanized mesh netting. These include: :
- Dimensions of galvanized mesh netting springs
- The type of wire used (these wires can be plain or ivory.)
- The volume and time required to manufacture your desired order
- The thickness of the wires used in the manufacture of galvanized mesh
- Use of galvanization, iron and steel in the structure of mesh nets
