Crash test results successfully proved pole sizes: 50, 65, 80, 90 & 100mm NB fell within the guideline of the NCHRP-350 Standard for open road conditions, and was subsequently approved for use by the FAC and Transit New Zealand.                                              

Vic Roads and Transport SA have since approved this product.                                                                 

The patented frangible pole system works in conjunction with a purpose made ground socket or sleeve designed to be a snug fit between pole and socket.
Depending on pole diameter and length sockets can be supplied up to 1200mm long and set in concrete foundations designed to local engineering requirements.
The socket top acts as the shear point, and combined with the molecular structure of the alloy, will under sudden impact bend at the impact point and ultimately shear and breakaway at the socket top.  

Pole flutes are designed to further assist the breakaway process by reducing the external surface area.

Both pole and socket are manufactured from          
high strength marine grade alloy with a 
typical yield strength of 275 MPa. This alloy has excellent age hardening qualities and will continue to strengthen 
over time.
