All our heavy duty fence panels are made to measure, we take the overall run then divide it to make equal panels, this gives better asthetics as there will be no half panels at one end. The panels are made using a 4" x 1 1/2" framework which is screwed together, the boards are nailed to the face. All timber is sawn finish and tanalied treated as standard. We generally fit the panels onto 4" square timber posts set in concrete, we also use post savers on the posts giving them an expected 20 year life span, we can also fit the panels onto concrete posts.
