UC4 Fence Posts
All timber used in contact with the ground or fresh water or in areas where there it is permanently wet should be treated to meet BS8417 to Use Class 4. Just because it is treated green or described as treated for longevity does not mean it is even suitable to be used outside.
UC4 Fence Posts in Kent
We treat Kiln Dried Radiata Pine on a specific cycle with a higher-than-average chemical concentration to offer a 30-year desired service life BS8417 part 4. This requires full sapwood penetration, not just 6mm penetration as required by incised spruce. Fixings and splitting in the timber may be greater than 6mm.
We normally hold in treated UC4 Radiata Pine for a 30-year desired service life the following fence post sizes:
145 x 145 | 95 x 95 | 75 x 125 | 75 x 75
