PVC-coated welded wire mesh is a type of fencing made from low carbon steel wires that have been welded together into a strong, durable mesh.The PVC coated welded wire mesh is commonly used in construction sites for temporary security fencing and crowd control barriers. Due to its excellent visibility and aesthetic appeal, PVC coated welded wire mesh is also often utilized in parks, gardens, and other recreational areas as decorative perimeter fencing. Moreover, the PVC coated welded wire mesh is suitable for agricultural uses such as animal enclosures and crop protection barriers against small animals. The PVC coating comes in a variety of colors, allowing the PVC coated welded wire mesh to blend in or stand out, depending on the project's requirements.Do you know how to choose the right PVC coated welded mesh for your project?

I. What is PVC coated welded wire mesh?

A.Welded wire mesh introduction

Welded wire mesh consists of low carbon steel wires that are welded together at each intersection, creating a strong and durable grid-like structure.The welds provide superior strength compared to woven mesh, making the welded wire mesh suitable for heavy-duty environments and security fencing. Its versatility makes welded wire mesh a cost-effective solution for numerous projects, from agricultural enclosures to animal cages and barriers in construction sites.

B.PVC coating welded wire mesh

In the manufacturing process of PVC-coated welded wire mesh where PVC coating is applied before welding, the initial step involves selecting high-quality low carbon steel wire. Each iron wire is individually coated with a layer of polyvinyl chloride (PVC) through a process called extrusion. During extrusion, the iron wire is passed through a heated PVC compound, ensuring an even and durable coating.

Once the iron wires are uniformly coated with PVC, the PVC iron wires are cooled and then prepared for the welding process. The coated iron wires are fed into a welding machine, which uses electrical resistance to weld the PVC iron wires together at their intersections, forming a strong and consistent mesh structure.

This method ensures that the PVC coating remains intact at the welded joints, providing superior corrosion resistance and longevity. After welding, the PVC coated welded wire mesh undergoes a final inspection to ensure quality and uniformity before being cut to size and packaged for distribution. This process results in a durable, aesthetically pleasing, and long-lasting wire mesh suitable for various applications.

II. PVC Welded Wire Mesh applications

Construction and Reinforcement: PVC coated welded wire mesh is used in construction projects for reinforcing concrete structures. PVC coated welded wire mesh provides a robust framework that enhances the strength and integrity of the concrete, making it ideal for residential and commercial buildings, as well as for infrastructure projects like roads and bridges .

Agricultural Applications: In agriculture, PVC coated welded wire mesh is used for creating animal enclosures, poultry housing, and to protect crops. Its rust-proof and durability make the PVC coated welded wire mesh a preferred choice for outdoor agricultural settings where it may be exposed to the elements and potential physical damage .

Industrial and Safety Applications: The PVC coated welded wire mesh is also utilized in industrial settings for safety barriers, machine guards, and to secure equipment. Its ability to withstand heavy use and provide a visual barrier without compromising on visibility makes the PVC coated welded wire mesh a practical choice for industrial applications .

How can you ensure that the PVC coated welded wire mesh you choose meets the requirements of your project?

III. Factors to Consider When Choosing PVC Welded Wire Mesh

   A. Mesh Size and Opening

Square Openings: Common sizes include 1/4 inch (6.35 mm), 1/2 inch (12.7 mm), 1 inch (25.4 mm), and 2 inches (50.8 mm).

Rectangular Openings: Sizes like 1/2 inch by 1 inch (12.7 mm by 25.4 mm) and 1 inch by 2 inches (25.4 mm by 50.8 mm) are also available.

How opening size affects application 

In construction, smaller opening sizes provide greater strength and resistance to tensile forces, making the PVC coated welded wire mesh ideal for reinforcing concrete structures such as floors, walls, and foundations. The smaller the opening, the more reinforcement the PVC coated welded wire mesh provides.For animal fencing, the appropriate opening size is determined by the size of the animals or objects that need to be contained. Larger openings are suitable for large animals, while smaller openings can be used for smaller animals or to prevent the entry of small animals or pests.

   B. Wire Gauge

The wire gauge of PVC coated welded wire mesh refers to the thickness of the iron wire used in the PVC coated welded wire mesh, which is an important factor in determining the strength and durability of the PVC coated welded wire mesh.

Wire gauge on strength and flexibility

For lighter uses such as garden fencing or decorative purposes, a higher gauge number (thinner wire) might be used. For example, the 22-gauge or 24-gauge wire could be used where strength is less critical but visual appeal is important.

For more robust uses such as animal enclosures or security fencing, a lower gauge number (thicker wire) is typically used. The 14-gauge or 16-gauge wire would provide a good balance between strength and cost-effectiveness.

In construction, where the welded wire mesh(usually galvanized welded wire mesh) is used for reinforcing concrete, lower gauge wires are preferred for their strength. The 6-gauge or 8-gauge wire is often used to ensure the welded wire mesh can withstand the stress and weight of the construction materials.

   C. Raw material

The PVC coated welded wire mesh is made from high-quality low carbon steel wire that is welded together to form the grid pattern. Low carbon steel wire is preferred for its high tensile strength and ability to withstand harsh environmental conditions.

SUNSHINE Group's PVC coated welded mesh is made from galvanized iron wire as the raw material, which offers significantly better durability compared to iron wire. Galvanization is a process that involves coating the iron wire with a layer of zinc, providing an excellent defense against rust and corrosion.Using galvanized iron wire ensures that the structural integrity of the PVC coated welded wire mesh remains intact, preventing early failures that could compromise security.

   D. Coating Thickness

Before Coating: Wire diameter typically ranges from 1.2 mm to 3.0 mm.

After Coating: Usually increases by 0.4 mm to 0.6 mm due to the PVC layer, making the wire diameter 1.6 mm to 3.6 mm.

The PVC coating thickness on welded wire mesh is a crucial factor that determines its durability, corrosion resistance, and overall performance. Different manufacturers may have varying standards and capabilities for applying PVC coatings.SUNSHINE Group's PVC coated welded mesh is durable and long-lasting, suitable for both indoor and outdoor applications.

   E. Environmental Considerations

Common colors for PVC coated welded wire mesh include dark green, white, black, and more. You can choose the right PVC coated welded wire mesh based on your project's needs. For instance, when creating a fence for animals like chickens and ducks running around in the grass, dark green PVC coated welded wire mesh can offer better aesthetics. Not only does PVC coated welded wire mesh come in a variety of colors, but it also features rust and corrosion resistance. Whether outdoors or indoors, and regardless of exposure to rain, snow, or UV rays, PVC coated welded wire mesh ensures the long-term use of your fence.

  F. Budget Constraints

Although the initial cost of PVC coated welded wire mesh is higher than that of iron metal fences, PVC coated welded wire mesh has low maintenance costs, good durability, and doesn't need to be replaced frequently. Moreover, PVC coated welded wire mesh has a wide range of applications, allowing you to choose the most suitable color for your project. Thanks to its excellent rust and corrosion resistance, PVC coated welded wire mesh has a long service life and ensures safety. Therefore, in the long run, PVC coated welded wire mesh offers good economic and safety benefits.
