<p>The coupling between a steel lamp post and a support comprises a support made from galvanised cast metal, while the bottom of the post comprises a hollow steel ring, also galvanised, which fits over the upper section (5) of the support, stopping against a shoulder (6). The bottom of the post and the upper section of the support can be octagonal in section, and the support can have lugs with slots in for fixing to the ground. ADVANTAGE - Galvanised surfaces prevent creation of electrical potential, leading to oxidation and corrosion of components.</p> |
