Black Wire Cloth (also known as Low Carbon Steel Wire Mesh) is made from low carbon steel wire that forms a mesh structure through weaving or other processes. Its main components include the following parts:

1. Low Carbon Steel Wire:

• Material: The primary material of black wire cloth is low carbon steel wire, which has a lower carbon content (typically between 0.1% and 0.3%), giving it better plasticity and ductility, while also providing sufficient strength.

• Characteristics: Low carbon steel wire is easier to process than high carbon steel wire and has a lower cost. Since it is not galvanized, it typically appears black or gray and is prone to rusting.

2. Mesh Structure:

• Weaving: The steel wire in black wire cloth is usually woven into a mesh structure. Weaving methods include plain weave, twill weave, and others, depending on the required mesh type and strength.

• Mesh Size: The mesh size of black wire cloth can be adjusted according to the application needs, typically expressed in millimeters (mm) or inches (inch). Common aperture sizes range from a few millimeters to several centimeters.

• Interwoven Connections: During weaving, the steel wires are interlaced to form a uniform mesh, with the intersections between each wire ensuring the stability of the structure and providing good load-bearing capacity.

3. Surface Characteristics:

• Non-Galvanized: The surface of black wire cloth is usually not galvanized, which is why it is referred to as "black" wire cloth. Non-galvanized low carbon steel wire tends to oxidize, giving it a black or gray appearance and making it susceptible to rusting in damp environments.

• Surface Oxide Layer: Due to oxidation, a thin layer of rust forms on the surface, which may affect its durability in some applications. However, in low-cost, short-term use scenarios, this can be economically advantageous.

4. Connection Methods:

• Woven Joints: During the weaving process, the steel wires interlace and are fixed together under pressure to ensure the stability of the entire mesh.

• Welding: Some types of black wire cloth are welded, where the interlaced steel wires are spot-welded together to form a stronger mesh structure. Welded joints enhance the overall strength and durability of the mesh.

5. Physical Properties:

• Tensile Strength: Low carbon steel wire has good tensile strength, enabling it to withstand a certain amount of external force and pressure.

• Elasticity: The elasticity of low carbon steel wire allows black wire cloth to adapt to some deformation, recovering its shape after deformation and continuing to function.

• Abrasion Resistance: Black wire cloth has a certain degree of abrasion resistance, making it suitable for long-term use in industrial environments.

The basic composition of black wire cloth (low carbon steel wire mesh) includes low carbon steel wire, the mesh structure, and a possible oxide layer. It forms a stable mesh through weaving or welding processes. This structure ensures the good strength, toughness, and cost-effectiveness of black wire cloth, making it suitable for various applications in construction, agriculture, industry, and screening.
