Welded wire mesh, or welded wire fabric, or "weldmesh" is an electric fusion welded prefabricated joined grid consisting of a series of parallel longitudinal wires with accurate spacing welded to cross wires at the required spacing.

Machines are used to produce the mesh with precise dimensional control. The product can result in considerable savings in time, labour and money.

Uses of welded wire mesh

[

The welded wire mesh is a metal wire screen that is made up of low carbon steel wire or stainless steel wire. It is available in various sizes and shapes. It is widely used in agricultural, industrial, transportation, horticultural and food procuring sectors. It is also used in mines, gardening, machine protection and other decorations.

Weld mesh is the term given to the kind of barrier fencing that is manufactured in square, rectangular or rhombus mesh from steel wire, welded at each intersection.

Welded wire fabric (WWF) is also sometimes used in reinforced concrete, notably for slabs.

This type of mesh is a square grid of uniformly placed wires, welded at all intersections, and meeting the requirements of ASTM A185 and A497 or other standards.[1] The sizes are specified by combining the spacing, in inches or mm, and the wire cross section area in hundredths of square inches or mm2. The common sizes are in the following table:

PVC coated welded mesh with plastic covering is constructed with galvanized iron wire of high quality. It has PVC powder covering that is processed by an automatic machine. The smooth plastic coating on this corrosion protective wire is attached with a strong adhesive which make increases durability of the wire. It is used in fencing residential and official properties like gardens, parks, building etc. The PVC coated welded mesh which is available as both rolls and panels, is also available in different colors like white, black, green etc.

Welded stainless steel mesh

Welded gabions are versatile and durable structures used in a variety of applications, from erosion control to landscape design. Choosing the right type of welded gabion depends on several factors, including the specific requirements of your project, environmental conditions, and aesthetic preferences. This article explores the different types of welded gabions and provides guidance on selecting the most suitable option for your needs.

Understanding Welded Gabions

Welded gabions are wire mesh containers filled with rocks, stones, or other materials. They are known for their strength and stability, making them ideal for numerous applications such as retaining walls, erosion control, and decorative features in landscaping. Unlike woven gabions, welded gabions are made from rigid, welded wire mesh panels, which provide a more uniform and aesthetically pleasing appearance.

Galvanized Welded Gabions

Galvanized welded gabions are coated with a layer of zinc to protect the steel wire from corrosion. This makes them highly resistant to rust and suitable for use in environments where they are exposed to moisture and other corrosive elements. Galvanized gabions are commonly used in retaining walls, riverbank protection, and coastal defenses.

The primary advantage of galvanized gabions is their durability and long lifespan. They are cost-effective and provide excellent performance in a wide range of applications. When selecting galvanized gabions, ensure that the zinc coating is thick enough to offer adequate protection, especially in highly corrosive environments.

PVC-Coated Welded Gabions

PVC-coated welded gabions offer an additional layer of protection beyond the galvanization. The PVC coating enhances the corrosion resistance of the gabions and provides added durability. This type of gabion is ideal for harsh environments, such as coastal areas or regions with high salinity, where additional protection against corrosion is necessary.

PVC-coated gabions are available in various colors, which can be used to blend the structure with its surroundings or meet specific aesthetic requirements. This makes them a popular choice for landscaping projects where visual appeal is important. The PVC coating also helps to protect the wire mesh from abrasion and damage during installation and use.

Stainless Steel Welded Gabions

Stainless steel welded gabions are made from high-grade stainless steel wire, offering superior corrosion resistance and strength. These gabions are ideal for environments where maximum durability and longevity are required, such as industrial applications, marine environments, and high-end architectural projects.

While stainless steel gabions are more expensive than galvanized or PVC-coated options, their exceptional durability and low maintenance requirements make them a cost-effective solution in the long run. They are particularly suitable for projects where exposure to harsh chemicals or extreme weather conditions is a concern.

Galfan-Coated Welded Gabions

Galfan-coated welded gabions use a special alloy of zinc and aluminum for coating the wire mesh. This coating provides enhanced corrosion resistance compared to traditional galvanized coatings, making Galfan-coated gabions an excellent choice for demanding environments.

Galfan-coated gabions offer a balance between cost and performance, providing superior protection against corrosion while remaining affordable. They are suitable for various applications, including retaining walls, erosion control, and landscape design, especially in areas with moderate to high exposure to corrosive elements.

Decorative Welded Gabions

For projects that prioritize aesthetics, decorative welded gabions are an ideal choice. These gabions come in various shapes, sizes, and finishes, allowing for creative and visually appealing designs. They are commonly used in landscape architecture, garden design, and as decorative elements in public spaces.

Decorative gabions can be filled with different types of materials, such as colored stones, glass, or recycled materials, to create unique and attractive structures. When selecting decorative gabions, consider the visual impact, durability, and compatibility with the overall design of the project.

Conclusion

Choosing the right type of welded gabion depends on the specific requirements of your project, including environmental conditions, durability needs, and aesthetic preferences. Galvanized, PVC-coated, stainless steel, Galfan-coated, and decorative welded gabions each offer distinct advantages for different applications.
