Is There A Reduction In Strength Compared To
Untreated Wood?
ò Yes. The treating and
drying processes cause a
á
reduction in strength that varies with treatment,
á
species of wood, applications and specific properties.
What Type of Fasteners Should Be Used With FRTW?
ò Galvanized steel
hardware is recommended. Although
á
the FR treatment does not increase the corrosion
of
á
bare steel, the galvanizing process provides an extra
á
margin of safety. Particularly in wet environments
á
such as with exterior FRTW.
