​Temporary Chain Link Fence for Construction Sites

Temporary Chain Link Fence for Construction Sites: Engineering for Safety and Compliance

Structural Specifications
Construction-grade temporary fencing utilizes 3.0-4.0mm low-carbon steel wire with tensile strength ≥380 MPa. Mesh openings typically measure 50×50mm (±3% tolerance) for optimal debris containment. Frames feature 38-42mm OD galvanized steel tubing (zinc coating ≥70μm) with diagonal cross-bracing at 45° angles to withstand 0.6kN/m² wind loads. Base plates (300×300×5mm) incorporate 4 anchor points compatible with:

• M12 expansion bolts for concrete

• 500mm ground spikes for soil

• 25kg sandbags for asphalt

Installation Protocols

• Perimeter layout planning with 2.4m setback from excavation zones

• Crew productivity: 350 linear meters per 4-person team per 8-hour shift

• Gates: Minimum 3.0m width for equipment access with dual-point locking

• Slope adaptation: Adjustable leg extensions accommodate 15° gradients

Safety Enhancements

• Anti-climb design: 75° inward-angled top rails

• High-visibility orange PVC coating (RAL 2010) with 70% light reflectivity

• Debris containment efficiency: 72% reduction in scatter radius per OSHA 1926.502

• Night safety: Reflective marker compatibility at 2m intervals

Maintenance & Compliance

• Weekly integrity inspections for mesh tension (≥300N/10cm) and frame alignment

• Galvanization repair: Thermal spray zinc to damaged areas

• Regulatory adherence: ASTM F668, CPWR Guidelines, and local building codes

• End-of-project decontamination: Pressure washing (80°C/100bar) for material reuse
