Sipo

Scientific name: Entadrophagma utile Sprague

Geographic origin: Africa

Sipo
Description

  • Sapwood: pink white.
  • Heartwood: reddish brown with light purple shades.
  • Fiber: Straight, Slightly intertwined fibers are very frequent.
  • Grain: Thin to medium size

Capacity of being impregnated

  • Sapwood: Medium capacity of being impregnated
  • Heartwood: No capable of being impregnated

Mechanization

  • Sawing process: No difficulties.
  • Drying process: Speed can vary from medium to high speed. Little risk of deformation and crack formation.
  • Planing process: No difficulties appart from risk of repelling produced by the intertwined fibers.
  • Gluing process: No difficulties.
  • Nailing and screwing process: No difficulties.
  • Finish: No difficulties
