The lifespan of an aluminium column is very long, especially if the root section is effectively preserved and the column is installed with care. The corrosion protection tape Sapa Pole Products applies, protects the ground portion of the column. The tape is extensively tested by TNO (a Dutch independent research organization) to make sure that the protection around the ground portion meets the European norms for lighting columns, the EN 40-6. Optimal protection can be obtained by means of our ground level protector. A lifespan of a traditional lighting column of more than 50 years are no exception. The aluminium lighting columns supplied by Sapa Pole Products satisfy all relevant norms, such as EN40-3-3.
