Van der Velden: “An example that illustrates the scale of the World Cup well is the 2014 World Cup in Brazil. Millions of visitors attend such an event. When so many people come together, the fences of Heras Mobile are of great importance.” The M500 Anti-Climb mobile fences are suitable for terrain enclosure. Unwanted visitors cannot easily enter the stadiums because these construction fences are difficult or impossible to climb over due to the narrow mesh size and vertical pins. Crowds of soccer fans are led in with crowd control barriers.
