Description 150mm Timber Posts (6×6) are UC4 pressure treated & suitable for a wide range of external applications – particularly gate posts. Did you know we only use Redwoods for our 150mm timber posts? Here’s why: Naturally resistant to insects, decay and warping. Strong and durable softwood. Highly effective for external uses. Other softwoods (such as Spruce) are more prone to warping, less attractive over time, and have a lesser life span. All of our ground contact timbers such Gravel boards and Raised Bed Timber are LONGLAST treated with a 15 year life expectancy. Want to learn more about UC4 treatment? See the WPA Guide → If you’d like to use these for hanging gates see our FAQ Gates Section for helpful information including guidance on sizes and our handy page dedicated to hanging gates All prices include VAT and are subject to change at short notice. Trade and Bulk prices are also available, enquire for more information.
