The outer and inner surfaces are protected against corrosion by hot-dip galvanizing, resulting in the galvanic coating thickness as shown in the table. The durability of anti-corrosion protection guarantees maintenance-free operation of our lighting poles and masts from dozen to several dozen years, depending on the ambient air (industrial, urban, coastal or rural). Posts and masts should be paint coated for use in highly aggressive air (i.e. Sulphur dioxide, nitrogen oxides, and salt). We can coat our posts and masts with paints in any colours on order, including special paint coats: dirt resistant coats, fluorescent coats, photo luminescent coats, chameleon effect coats, and many more. Special coats may extend the life of the products.
Tubular posts for in-soil installation should have the soil contact portion coated with a bituminous compound.
Galvanic coating thickness on non centrifuged parts (EN ISO 1461 Table2)
| Steel thickness, mm | ||
| Local coating thickness (minimum) | Mean coating thickness (minimum) | |
| ≥1,5 to <3 | 45µm (315g/m2) | 55µm (385g/m2) |
| ≥3 to <6 | 55µm (385g/m2) | 70µm (485g/m2) |
| ≥6 | 70µm (485g/m2) | 85µm (585g/m2) |
