Stainless steel (AISI 316) is not affected. [7] Aluminium and Galvalum fasteners should be avoided. [8] One should use fasteners made of hot-dipped galvanized steel, copper, or ...
The "Bethell process"—or as it later became known, the full-cell process—involves placing wood to be treated in a sealed chamber and applying a vacuum to remove air and moisture from wood "cells".
