The above class resistance is defined as 656,000 joules energy adsorbed, which is roughly equal to a truck weighing 6800kg travelling at a speed of about 50 Km/hour (30Mph). It differs from standard bollards for its extremely high resistance.
J355HA-M30 painted steel
– Steel cylinder, thickness 16 mm treated with cataphoresis and painted
– Powder-painted dark grey metalised RAL 7021
– LED lamp on the head
– Operated by hydraulic unit built-in on the bollard
– Raised position available in event of power failure, by means of hydraulic locking
Bollard Pit JP355
The pit is made of steel sheet aluzinc, with a thickness of 2mm. The main frame is ductile iron GS400 molded, treated with cataphoresis.
The pit is sealed with a hole in the side for channeling water to the sewer system and with a hole for cables at the top.
In the case of special requirements, the hole can be sealed to prevent the entry of water from the subsoil (marine areas, near rivers, etc.).
The particular arrangement of reinforcing steel bars that are not near the surface, allows the finishing of the site, respecting
any architectural constraints of the pavement (asphalt, stones, etc..) up to 15cm from the base of the bollard.
Reinforcing steel bars of the foundation (they are common steel bars and wire mesh for construction work; not supplied),
equips the bollard and its pit with the resistance that ensures compliance with the ASTM standards, class M30.
