Northern Red Oak

Scientific name: Quercus rubra L.

Geographic origin: North America.


  • Sapwood: varies from light gray to pale red
  • Heartwood: varies from pinkish to pale red or light brown
  • Visible woody rays, they present the classic mirrors in the radial section

Capacity of being impregnated

  • Sapwood: capable of being impregnated.
  • Heartwood: from medium to low capacity of being impregnated.


  • Sawing process: no difficulties, excepting hardness.
  • Drying process: slow-very slow. Risk of collapse and cementation. Risk of crack formation.
  • Planing process and other processes: those ones characteristic of its hardness.
  • Gluing process: difficulties can arise from the use of alkaline glues and acid adhesives.
  • Nailing and screwing process: easy.
  • Finish: easy.

Northern Red Oak

  • It is a cheaper alternative to American White Oak, with greater variation of tonalities and somewhat more porous.
  • Wood packages with a good average width.
