The coating improves dielectric performance and increases the longevity of the cross-arm.  The coating is not a standard powder coating.  It is a high performance thermoplastic alloy.  Its performance makes it suitable and durable for playgrounds, underground pipes and marine environments, for example.

The sleeve protects the pole at the ground line from line trimmers and above the ground acid (such as form dogs), but more importantly, the sleeve protects the steel pole in the oxygen rich layer below the ground, from corrosion.

The sleeve is available in three standard lengths (1,000mm, 2,400mm, 4,800mm). This means the level of protection of the asset can be tailored to environmental conditions. There is also an optional boot that encloses the sleeve at the base of the SURELINE® pole.

Zinc will always corrode in preference to steel.  This effect is known as sacrificial protection. Therefore the steel will only begin corroding once there is no zinc present. Simply apply a two-pack zinc-rich primer over the hole to restore protection.

Steel poles/structures have a similar conductivity to concrete.  Like other steel structures or concrete, the SURELINE® solution requires grounding.

The poles can be used in most environments.  SURELINE® has a range of solution options for long life in various environments. SURELINE®'s asset management information will help you select the best solution for your needs.
