Norwegian spruce (Picea abies) lumber specifications include: it is a lightweight, strong, and easy-to-work-with softwood with a creamy white to yellowish color and fine, straight grain. Its density ranges from approximately 405-470 kg/m³ (25-29 lbs/ft³). It is classified into structural strength classes, such as C24, per EN 338 for construction. The wood glues and finishes well with a recommended sanding sealer or gel stain for consistent results.
Key Specifications
Botanical Name: Picea abies
Material Type: Softwood
Density: 405–470 kg/m³ (25–29 lbs/ft³)
Color: Creamy white with a hint of yellow or red
Grain: Fine, even, and consistently straight
Workability: Easy to work with, but can be blotchy when stained without a sealer
Mechanical Properties
Modulus of Rupture (MOR): 63.0 MPa (9,130 lbf/in²)

Janka Hardness: 380 lbf (1,680 N)
Applications
Construction: Ideal for framing, wall studs, floor and ceiling joists, beams, and trusses
Interior: Suitable for decorative finishes, panelling, and furniture
Other: Used for packaging, crates, and other heavy-duty applications
Grading and Standards
European Standards: Structural timber is graded according to the EN 338 standard into various strength classes, such as C24.
NELMA: The North American component of the Wood Products Association, which grades the species for use in building.
Important Considerations
Staining: The closed-pore structure can lead to inconsistent results. A sanding sealer, gel stain, or toner is recommended to achieve a uniform finish when coloring Norwegian spruce.
Durability: The heartwood is only slightly resistant to decay. For increased service life in outdoor or above-ground applications, treatment may be required.
