Crowd control barriers are typically made of high-quality carbon steel, which provides strength and durability to withstand the wear and tear of heavy usage. They are designed to be corrosion-resistant, which helps to ensure their long service life even in harsh environmental conditions.

The barriers consist of individual sections that can be linked together to form a continuous barrier, which can be easily assembled and disassembled as needed. Each section typically measures around 2-3 meters in length and 1-2 meters in height, with a weight of approximately 10-20 kg per section.

The barriers are designed to be easily linked together to create a continuous barrier and can be arranged in various configurations to suit different needs. They may feature wheels or locking mechanisms to enhance their mobility or security.

Crowd control barriers are also designed to be highly visible, with bright colors or reflective materials to make them easily identifiable in low-light conditions. They may also feature signage or other markings to help direct the flow of pedestrian traffic.
