Planed Impregnated Wooden Post 7×7×240 cm – Class 4, Finnish Pine

The planed impregnated wooden post 7×7×240 cm is made from solid Finnish pine and has been pressure-treated to Class 4, the highest level of protection for outdoor use. It provides exceptional durability against time, moisture, and microorganisms, making it ideal for all constructions exposed to weather conditions.

What Class 4 Impregnation Means

Class 4 impregnation (according to European standard EN 335) applies to wood intended for:
- direct contact with the ground or fresh water
- continuous outdoor exposure
- high-humidity environments or frequently stressed areas

The wood is pressure-treated with eco-friendly preservatives (free from arsenic and chromium) that penetrate deep into the fibers, making it resistant to rot, fungi, insects, and decay. This process ensures a lifespan exceeding 15–20 years in outdoor applications.

Advantages

✅ Resistant to moisture, water & decay
✅ Safe & eco-friendly – no heavy metals
✅ Planed surface for a smooth finish
✅ Finnish pine origin – dense grain & dimensional stability
