Anti-crash bollards are specially engineered posts intended to withstand high-impact collisions from vehicles. Unlike traditional bollards that merely serve as guides for traffic or to delineate pathways, anti-crash bollards are built to absorb significant forces. Depending on their design and installation, they can effectively stop vehicles traveling at speeds up to 50 mph or more, providing a critical line of defense in urban environments. Their effectiveness has made them indispensable in securing government buildings, airports, stadiums, and pedestrian-heavy zones.

The Gully Grid A Vital Component of Urban Drainage Systems

Originally, manholes were primarily used to provide access to the sewage system beneath the ground. The ancient Roman Empire was famous for its aqueducts that brought water into the city and carried sewage out. In the United States, as technology advanced and homes and buildings began using gas, electricity, and telephones, the approach to laying pipes and placing sewer lines underground was already in place. Other utilities began to join sewers in the underground network of pipes accessed through manholes.

Moreover, as cities strive to become more green and sustainable, ground-embedded bollards can be designed with eco-friendly materials, adding an additional layer of environmental consciousness to urban infrastructure.
