fence
A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along its whole length.

It tends to be easy to clean, resists weathering and has low maintenance requirements. However, it also can be more expensive than comparable materials, and cheaper products can be less sturdy than more traditional fence materials. Some types may become brittle, faded or degrade in quality after long exposure to extreme hot or cold conditions. Recently,

This has greatly improved the durability of vinyl by providing essential UV protection from the sun's harmful rays, preventing premature ageing and cracking of the product, making it more durable than other materials such as wood.
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. For
agricultural use, synthetic fencing can consist of a heavy synthetic strapping product inlaid with cable, synthetic-coated high-tensile wire, or a synthetic coating over a wood or metal rail or plank. Residential synthetic fencing products are usually hollow, and thus too fragile to contain
