1. Material Properties: European Oak
Property Value Source / Standard
Botanical Species Quercus robur / Quercus petraea
Janka Hardness 1290 - 1360 lbf (approx. 5590 N)
Density ~700 kg/m³ (at 8-10% moisture content)
Durability Class Class 2 (to EN 350)
Drying Method Kiln-dried
Moisture Content 8% (as supplied)
European oak is measurably harder than American oak (approx. 1290 vs. 1220 lbf) and significantly more durable than softwoods like pine (~380 lbf). Its cellular structure allows it to absorb and release moisture evenly, making it dimensionally stable across seasonal humidity changes.
