Description:

Welded wire mesh is a prefabricated steel reinforcing material. It is manufactured from S220 cold drawn, ribbed and high yield
strength steel wires especially used in construction.

Welded Wire mesh can be produced in two different shapes based on their placement working principle
1. R Type meshes for one way placement.
2. Q Type meshes for dual way placement.

 

Technical Specifications:

 

Areas of Use:

As a construction material, welded wire mesh is used especially in reinforcing all sorts of concrete structures such as slabs, walls, webs, beams, column footing, highways, tunnels and galleries. However, apart from these, there are other available welded wire mesh types
which are used for garden fencing, safety railings and suspended ceilings. According to the customer demand, these can be manufactured as hot dipped galvanized and polyester painted.

Advantages:

The yield strength of wire mesh is 2.27 times higher than S220 steel and 1.19 times higher than S420 steel. In other words, our production of welded wire mesh provides economy in steel consumption up to 10%, in time and labor up to 25%.

Projects:

The types of welded wire mesh to be used are calculated according to project moments and concrete grade. In compliance with the formwork, the reinforcement drawings are completed. In order not to mislead the type of the wire mesh, two plans, one called the bottom reinforcement drawing to meet the spacing effects and the other called the upper reinforcement drawing to meet the propping effects, are drawn. Moreover, within every reinforcement drawing, a wire mesh cutting plan is to provided to show the cutting points and
the dimensions required for the placement of the meshes, which are also necessary to calculate the amount of steel to be used.

Application projects of the wire mesh for every type of construction works and required technical support during their application is provided by Demma is free of charge.

Over Lappings On Wire Mesh:

In practice, the wire mesh is placed as 3 eyelets (50cm.) in the carrier direction and as 2 eyelets (35cm.) in the distribution direction.

• On the edges of the wire mesh with double wires, reducing of side wires should be performed as: 3 eyelets in Q types and 2 eyelets in R types.
• Since the jutting of the transverse and longitudinal wires of the wire mesh are normally 10 cm and 17.5 cm, they can be easily inserted into beams and columns.
• In the concrete laid fields, depending on the cross sections of the wires, it shall be best suited if the wire meshes are over lapped minimum by two eyelets.

Standards and Specification Of Welded Wire Mesh Production:

Our production complies with Turkish Standards TS 4559 but our factory is well capable of producing according to DIN, BS and ASTM standards up on request. Standard sizes are normally held in stock are 2.15 m. by 5.00 m. According to the customer’s requirements, special dimensions can be manufactured but the order has to be above a certain quantity.

                

Besides the dimensions mentioned above, Demma is capable to produce customized welded wire mesh products.

Industrial Wire Mesh: Enhancing Functionality and Safety in Various Industries

Introduction:

Industrial wire mesh plays a vital role in numerous industries, providing practical solutions for applications such as filtration, safety, architecture, and agriculture. This versatile material consists of interconnected wires arranged in a grid-like pattern, forming a strong and durable mesh structure. In this article, we will explore the different types of industrial wire mesh, key factors to consider when choosing wire mesh, its diverse range of applications, and essential maintenance tips to ensure optimal performance.

Types of Industrial Wire Mesh

  1. Welded Wire Mesh: A Sturdy and Versatile Choice

Welded wire mesh is manufactured by welding intersecting wires together at their contact points. This construction technique results in a rigid and uniform mesh that offers exceptional strength. It finds applications in various industrial settings, including construction, manufacturing, and agriculture. The advantages of welded wire mesh include high structural integrity, excellent visibility, and straightforward installation. However, its rigidity may limit its adaptability to curvedshapes or irregular surfaces.

  1. Woven Wire Mesh: Versatility with Precision

Woven wire mesh is created by interlacing wires in an over-and-under pattern, forming a flexible and customizable mesh structure. It offers a wide range of mesh sizes, wire diameters, and weaving patterns to meet specific application requirements. Woven wire mesh finds extensive use in industries such as mining, pharmaceuticals, and architecture. Its advantages include excellent filtration capabilities, good airflow, and aesthetic appeal. However, the small openings in finer meshes may restrict the passage of larger particles.

  1. Expanded Metal Mesh: Strength with Openness

Expanded metal mesh is produced by cutting and stretching a solid sheet of metal, creating a mesh with diamond-shaped openings. This type of wire mesh offers high strength, rigidity, and openness. It is commonly utilized in industrial sectors such as security, infrastructure, and automotive. Expanded metal mesh provides enhanced visibility, good ventilation, and efficient drainage. However, it may not be suitable for applications requiring fine filtration due to its larger openings.

  1. Perforated Metal Mesh: Precision with Functionality

Perforated metal mesh is manufactured by punching or drilling holes into a metal sheet, creating a pattern of openings. This type of wire mesh offers precise hole placement, size, and shape, making it suitable for various industries, including architecture, acoustic engineering, and food processing. Perforated metal mesh provides excellent airflow, sound absorption, and structural support. However, its solid surface area may limit visibility and drainage capabilities.

Key Factors to Consider When Choosing Industrial Wire Mesh

  1. Material Selection: Matching Strength with Application

Industrial wire mesh is available in various materials such as stainless steel, galvanized steel, aluminum, and brass. Each material offers unique properties such as corrosion resistance, strength, and conductivity. When selecting wire mesh, consider the specific requirements of your application, including environmental conditions, chemical exposure, and load-bearing capacity.

  1. Mesh Size and Openings: Balancing Filtration and Flow

The mesh size and openings of wire mesh determine its filtration capabilities and the passage of materials. Finer meshes with smaller openings provide better filtration but may reduce airflow or fluid drainage. Coarser meshes with larger openings allow for increased flow but may compromise filtration efficiency. Evaluate the particle size or material you need to filter and choose the mesh size and openings accordingly.

  1. Wire Diameter and Gauge: Strength and Durability

The wire diameter and gauge of industrial wire mesh influence its strength and durability. Thicker wires offer increased strength but may decrease flexibility. Thinner wires provide greater flexibility but may compromise strength. Consider the mechanical requirements of your application, such as load-bearing capacity and impact resistance, to select the appropriate wire diameter and gauge.

  1. Surface Finish and Coatings: Protection and Performance

The surface finish and coatings applied to industrial wire mesh affect its resistance to corrosion, abrasion, and other environmental factors. Common finishes include galvanized, PVC-coated, and epoxy-coated. Choose a surface finish or coating that aligns with the specific demands of your application, such as exposure to moisture, chemicals, or extreme temperatures.
