Synthetic fence

Some types may become brittle, faded or degrade in quality after long exposure to extreme hot or cold conditions.

[3] Synthetic materials used for residential fences can be in a solid cast form, or a reinforced hollow rail design that resembles sawn timber, Most commonly extruded profiles.

Higher quality vinyl fence components are ribbed or include reinforcements, often of aluminium, for added strength.

Residential synthetic fencing products are usually hollow, and thus too fragile to contain livestock, but some designs may be suitable for containing dogs or other pets.

Usually this ability to resist discoloration leads many manufacturers to offer very long warranties, from decades up to "lifetime" for some brands.
