SPRUCE (PICEA ABIES)

The spruce, commonly called the “Christmas tree” or “White wood” comes to Morocco from Scandinavia (Sweden, Finland) and Russia. Light and strong, this is the ideal wood for interior joinery, manufacturing of frames, doors, windows, or glulam beams, as well as for the production of reels, pallets and packaging.
