Exterior staircase stringer for steps, solid pine wood, impregnated

Pressure-treated pine wood

The durability of native European pine wood  is significantly improved through professional pressure impregnation, protecting it from pests. The softwood is easy to work with and does not require pre-drilling. The surface is planed smooth on all four sides.

Pressure impregnation  includes green pigments as markers. These can be more or less visible depending on the wood’s characteristics. Sometimes, salts may crystallize. These will weather away over time and are perfectly normal for impregnated wood.
