01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become 목재.
Making 목재 is a chain: feedstock, conversion (Palaeolithic tools; CLT 1990s Austria), forming, heat, finish, install.
Skip a step and the properties chapter is describing a different object.
공정 단계
02 Conversion
Palaeolithic tools; CLT 1990s Austria
03 Forming
Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
04 Heat / cure
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
05 Finish
Coatings, sizings, facers, galvanizing, anodising, painting.
06 Install
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
경로
Primary
Virgin route around Global forests / Graz.
Recycled / secondary
목재 has a real loop when sorting is honest.
Specialty
High-spec grades leave the commodity mill.
Site-applied
Coatings, sprays, casts — the factory is sometimes a jobsite.

한계
Envelope
Melting/softening chars ~200–300 °C; does not melt; conductivity ~0.1–0.2 W/m·K along vs across grain.
Environment
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills 목재.
Code
Fire class D–B depending on product / treatment is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
