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
