The SP400 is the first removable bollard to be installed and impact tested within a suspended slab foundation.
Traditionally, suspended slab applications such as bridge decks, car park ramps or infrastructure over an underground tunnel such as London Underground Stations have proven a unique challenge for installing impact tested bollards. With our latest innovation, the historical concerns of damaging the integrity of a suspended slab structure and ultimately the surrounding integral infrastructure can be reassured.
Building on an extensive portfolio of impact tested products, we conducted two developmental impact tests to certify the use of a removable bollard within a suspended slab foundation. The suspended slab had a thickness of 250 mm and the product was impacted with a 2,500 kg vehicle travelling at 48 kph (30mph). After impact, the integrity of the suspended slab was completely retained and the removable bollard performed a dead-stop with zero meters of penetration recorded.
The tests provided us with a wealth of data, and the calculations gained can be used to design a security solution for your suspended slab application.
The SP400 bollard itself has a slim profile, giving it a sleek look and allowing it to be fitted with a flawless stainless steel sleeve. It comes galvanised as standard to protect against corrosion and two reflective bands to help with visibility.
