Lighting columns are susceptible to corrosion at the base, due to splashes and ground
water, and the collar (swage joint) often due to condensation built up inside the
column. Regular inspection of lighting columns is recommended to ensure they are
maintained in good condition and are structurally safe to prevent the column from
collapsing and causing possible injury.
Local governments and authorities are usually required to carry out thickness measurements
on a regular basis along local roads and highway networks.
Measurements are typically taken at four points around the circumference at different
heights on the lighting column.
Using a Multigauge 5600, H&FC have tested around 7000 lamp columns, populating our
existing database, identify defective columns and allowing the street lighting engineer
to prepare a forward programme"
