 These are Red Pine, Rough Sawn, and are currently being treated with MCQ (Micronized Copper Quat). They have a limited lifetime warranty for ground contact. They are a high quality lumber; with a traditional rough finish (not planed and smooth to the touch). These timbers are for in-ground use.
When shopping for timbers be sure to find out what kind of wood they are made from. SPF or spruce/pine/fur wood are much less expensive to produce but are much more likely to degrade by warping, drying, and cracking. For all timbers being produced now the treatment is highly corrosive, so be sure to use stainless steel, heavily galvanized spike, or screws specifically intended for treated wood.
For long term preservation of treated timbers; cuts and bore holes need to be liberally coated with a suitable wood preservative, e.g. Copper Napthenate solution containing minimum 1% metallic copper. The timbers are also very corrosive to metal, only use connecters which are meant for use with pressure treated timbers. |
