1. AND: Retractable barriers are made of impactresistant, fiberglassreinforced epoxy resin that will not fade or rust when exposed to sunlight, wet conditions, UV radiation, or harsh weather. The visible yellow and black colors resist fading from UV light or adverse weather. 2. MORE PRACTICAL DESIGN: Our barriers can extend to cover large areas of 2m/2.5m/3m/3.5m/4m/5m/6m, allowing quick isolation of any hazardous or restricted zones to protect surrounding individuals. They also fold down to less than 0.3m for compact storage and easy portability. 3. VISIBLE REFLECTIVE STRIPS: The red and black reflective strips enhance visibility, ensuring the barriers stand out day or night from any angle. This improves nighttime recognition and effectively alerts pedestrians. 4. EASY INSTALLATION: Our expandable mobile barrier system is simple to set up, with all tools included. These fences clearly mark restricted areas, ensuring hazards are enclosed by our noticeable barriers.
