In scenarios such as workshop isolation and area division, double-wire mesh fencing has become a popular choice due to its low cost and easy installation.
Double-wire mesh fencing, as the name suggests, refers to a fence where both sides of the mesh panel are inlaid with thick wires. This allows it to be directly connected and fixed to posts using anti-theft screws, resulting in a simple structure.
Materials and Wire Diameter
* Material: Typically uses Q235 low-carbon cold-drawn steel wire. This is the basis for ensuring the strength of the mesh panel.
* Wire Diameter: Refers to the diameter of the steel wire, commonly ranging from 2.8mm to 6.0mm. The thicker the wire diameter, the better the durability.
2. Mesh Size
* Common specifications include 50mm × 50mm (square or rhomboid holes) and 75mm × 150mm, etc.
* When choosing, mainly consider the size of the objects you need to block. The smaller the mesh size, the more secure the protection, but the cost and weight will increase accordingly.
3. Corrosion Protection Treatment
This is crucial in determining the service life of the fence! Please pay close attention to the following:
* **Dip Coating:** A common treatment method, resulting in a thicker coating and good corrosion resistance.
* **Powder Coating:** A thinner coating than dip coating, but still provides good rust and corrosion resistance.
* **Hot-Dip Galvanizing:** Offers the strongest corrosion resistance, ideal for humid or coastal environments, but is also more expensive.
4. Overall Process
* **Check the weld joints for firmness, uniformity, and any incomplete or missing welds.** High-quality welds ensure structural stability.
Its core advantages are prominent: low cost, convenient transportation (can be disassembled and bundled), and flexible and efficient installation (not requiring high ground flatness). However, its protective and impact resistance are relatively weaker than framed guardrails. Therefore, it is more suitable for internal area division in workshops and warehouses, site isolation where high protective strength is not required, or as auxiliary guardrails for highways.
