Corrosion of fasteners in furfurylated wood : final report after 9 years exposure outdoors
Corrosion of some common fastener materials – mild steel, stainless steel, zinc-coated steel, brass and Sanbond Z (nickel, zinc and chromate) coated steel – has been evaluated after nine years’ exposure outdoors in untreated Scots pine and furfurylated beech and Southern yellow pine (SYP). The furfurylation was carried out according to a process that resulted in approximately 40 % Weight Percent Gain (WPG). The results show that the corrosion of fasteners in furfurylated wood according to the particular specification is considerably more severe than in untreated wood and very similar to the corrosion caused by thermally modified wood. Mild steel and zinc coated steel have been most susceptible. Stainless steel has not been attacked at all and is therefore strongly recommended for furfurylated wood in outdoor applications.
