Welded wire mesh, often referred to as welded wire fabric, is a versatile construction material consisting of low carbon steel wires welded together at each crossing point to form a strong and stable mesh structure. The welded wire fence is characterised by high tensile strength, durability and corrosion resistance, making the welded mesh fencing suitable for various applications such as structural reinforcement, fencing, security barriers and shelving. The welded fence mesh is available in a variety of finishes including galvanised,and PVC coated to meet specific requirements and provide additional protection from the elements.
Specification
Galvanized welded wire mesh is a type of low carbon steel wire mesh fence that has been coated with zinc to enhance its durability and resistance to corrosion.This process can be done either before or after the mesh is welded, resulting in two types: galvanized before welded wire mesh,galvanized after welded wire mesh.
The service life of welded wire fencing that is galvanized before welding is longer than that of welded mesh fence which is galvanizing first and then welded. If you weld the mesh fence before galvanising, the coating will be uneven on the welding points and the welded wire mesh will rust more easily.
And there are two types of galvanized manufacturing process:
Hot-dipped galvanized welded wire mesh, involves dipping the welded mesh fence into molten zinc, creating a protective coating that is highly resistant to rust and corrosion.This method provides a strong anti-corrosion layer(35-250g/m2), with good adhesion and hardness, making it difficult to peel off and extending the lifespan of the hot-dipped welded wire mesh.The process includes steps such as heating, cooling to the required temperature for galvanization, and then cooling again before storage.
On the other hand, electro-galvanized welded wire mesh uses an electrolytic process where the welded mesh fencing is coated with zinc through electrolysis without the need for heating(15-38g/m2), which makes it less resistant to corrosion compared to hot-dip galvanizing.
Galvanized welded wire fence offers several advantages beyond rust and corrosion prevention.
Aesthetic Appeal: Galvanized welded wire fences offer a clean, modern appearance that can complement a variety of settings.
Versatility: The galvanized welded fences can be used for a range of applications, including security, agriculture, construction, and residential boundaries.
Low Maintenance: Due to the galvanized coating, the hot-dipped galvanized welded wire mesh require minimal upkeep and do not need frequent painting or treatment to maintain their protective qualities.
Safety: The smooth and uniform surface of the galvanized welded wire mesh reduces the risk of injury, making it safe for use around children and animals.
What size galvanized welded wire mesh do you need?
The galvanized welded wire mesh provides rectangular or square hole mesh,the widely used rectangular mesh sizes for your construction projects are:1x1/2 inch welded wire,1x2 inch welded wire mesh,2x3 inch welded wire fence,2 by 4 inch welded wire fencing.
