A comparative study of some anti-splitting devices, using Eucalyptus saligna and hybrids of Eucalyptus saligna X Eucalyptus spp poles

It is commom for some Brazilian wood pole users to require devices such as banding steel, to avoid or reduce splits at the end of Eucalyptus treated poles. On other hand users and manufacturers do not have data to confirm the effectiveness of the banding steel types normally used such as galvanized "Steel-Belt" and galvanized "Wire-Belt". For this reason a comparative study was carried out including in addition to the above, "Steel-Plates" (Gang-Nail type) and the "Kerfing" procedure. These devices were tried out on Eucalyptus saligna hybrids, species which present a strong tendency to split. Based on the results obtained in four bimonthly inspections of 80 poles (including a control series) and based on the statistical analysis, it was noted that the "Steel-Plates" (Gang-Nail type) contributed to reduce splits in the ends of Eucalyptus poles.
