TTT Marine Poles & Timber

Any wood products that are exposed to regular immersion in sea water or installed in estuarine ground are considered to be used in Marine situations. Poles and Timber for use in Marine situations should be treated to H6 Hazard Class. In order to meet the stringent requirements of the H6 Hazard Class much higher levels of CCA preservative are needed, and the preservative must penetrate further into the wood.


Marine Poles

TTT Products manufactures and stocks a comprehensive range of poles for use in many differing situations, including Marine Poles.

Any of our comprehensive range of poles can be treated to H6 Hazard Class for use as Marine Poles:

TTT SED Poles are naturally tapered poles typically for use in construction, retaining, and marine piling.

TTT Uglies are similar to SED Poles but they are debarked rather than peeled so look 'ugly' as a result. Generally they are used in situations out of sight.

TTTested Poles are poles that have undergone rigorous proof-testing on our verified testing rig.

TTT MultiPoles are versatile poles with a unique hollow core


Marine Timber

In order to achieve the levels of penetration and retention required for H6 Hazard Class sawn timber must be of an extremely good grade - usually a 'clear' grade of timber. Standard No. 2 Grade Retaining Timber or MSG8 Timber will generally not meet the grade.


H6 Hazard Class

While the grade of timber, and the compliance with H6 Hazard Class is guaranteed, the preservative supplier will not guarantee any length of performance for H6 treated products. This is due to the extreme conditions that make up any Marine situation.

To improve the longevity of your H6 treated product it is especially important that the product is treated after all cutting, drilling, and other processing is completed. This is to ensure there is an unbroken envelope of preservative surrounding the wood. TTT Products can assist with pre-drilling and cutting to length before treatment.

H6 Hazard Class requires a minimum of 40mm penetration of the preservative into the wood, with all of the sapwood treated. The copper loading required is 0.4% weight for weight.

To provide added durability and resistance to insect attack in a Marine situation TTT Products can apply a Plastic Polymer Coating. Please see our Plastic Polymer Coating page for more information.
