Chain link fencing, also known as chain link barrier net, is a protective isolation facility that uses chain link mesh as the net surface. The following is a detailed introduction:

Material

• Metal Wire: Common types include high-quality low-carbon steel wire, stainless steel wire, aluminum alloy wire, etc. Galvanized wire or iron wire can also be used.
• Plastic Wire: Such as PVC wire, often used for plastic-coated chain link mesh to enhance corrosion resistance and aesthetics.

Specifications

• Mesh Size: Mostly diamond-shaped, with aperture generally ranging from 4-100mm. Commonly used sizes include 40mm, 50mm, and 60mm.
• Wire Diameter: Generally between 1.8-6mm. For example, the plastic-coated wire diameter commonly used in stadiums is around 4mm, while for general protection, it may range from 3-5mm.
• Dimensions: Net length is typically 1-10m, and net width is 1-4m. Customization is available based on actual requirements.
• Frame and Posts: The frame usually uses 48*1.5mm round tubes, and posts typically use 60*2.5mm round tubes.

Weaving and Features

• Weaving Method: Woven by a chain link weaving machine from metal wires, which can be divided into two types: folded edge with tightened knots and twisted edge with locked knots.
• Features: Uniform mesh, flat net surface, simple weaving, elegant appearance; high-quality wire, wide net width, thick wire diameter, corrosion resistance, long lifespan, and strong practicality.

Surface Treatment Methods

• Electro-Galvanizing: Thin zinc layer, low cost, average corrosion resistance.
• Hot-Dip Galvanizing: Thick zinc layer, strong corrosion resistance, suitable for harsh environments.
• Plastic Coating: Such as PVC or PE coating, good corrosion resistance, rich color options, aesthetically pleasing, and durable.
• Plastic Dipping: Thick coating, good corrosion and wear resistance.
• Powder Coating: Provides good corrosion resistance and decorative effects.

Installation Methods

• Measurement and Marking: Determine the centerline of posts based on drawings and actual terrain.
• Ground Preparation: Replace and compact weak soil layers under the foundation to ensure post stability.
• Excavation of Foundation Pits: Excavate post foundation pits according to measurements and markings, ensuring proper dimensions.
• Post Installation: Ensure posts are stable, tightly connected to the foundation, and check for straightness.
• Net Installation: Securely connect the chain link mesh to the posts, ensuring the net surface is flat without warping or bulging.

Applications

Widely used for guardrail net facilities on highways, railways, expressways, etc. Also used for indoor decoration, animal breeding and zoo enclosures, machinery and equipment protection, sports field fencing, roadside green belt protection nets, and for protective reinforcement in civil engineering, such as manufacturing galvanized gabion nets to protect seawalls, slopes, etc.
