Fence panels are often consisted of segments, or fence panels, as opposed to a single segment that leaves the whole perimeter. Fencing panels could be constructed from wood, metal, vinyl, concrete, or many other composite components. All panels have vertical or horizontal boards on the outer face, and two or more cross members keeping them all together. Having fences divided into several, individually sold components (or sets) provide a more significant level of flexibility during installation.

A regular fence panel is 5 to 8 feet in length. To find out the variety of panels really needed, you first must choose a basic panel overall length. You would measure the number of feet of the perimeter being enclosed, and divide this by the length of each panel. Posts are installed in time periods of the panels' length (e.g. one post every 8 feet), and each post is centre in between the panels, which are generally fastened with lag screws - even though some metal posts are pre-punched for less complicated mounting.
