Fiberglass Posts: Light, Flexible and No Insulators Needed

Fiberglass Posts: Slim Posts with Plenty of Flex

Fibreglass posts are made of glass fibre reinforced plastic. They are light, very flexible and do not conduct electricity. That means you can fix polywire or polyrope directly to the post with simple clips. For strip grazing, subdivisions and fences in windy spots, fibreglass posts are a proven solution. They stand slim in the landscape and are easy to carry in large numbers.

Oval, Round or with a Metal Tip

Oval fibreglass posts are a little stiffer in one direction and twist less when the conductor is tensioned. Round posts are compact and make good light line posts. Models with a metal tip go into firm ground more easily and protect the fibreglass when you drive them in. At 70 cm you have a short post for low fences, at 106 to 110 cm you cover cattle and sheep fences, and 152 cm is enough for horse paddocks. The posts are light enough to carry a whole armful across the field.

Support for Electric Netting

Electric netting sometimes sags between its posts, especially in dips or on long runs. A fibreglass post for netting or a post with a double spike can be pushed in quickly as an extra support and lifts the net back up. That keeps sheep, goats or poultry safely behind it. When handling fibreglass, wear gloves if the surface of older posts has become rough. In windy spots, an extra post in the middle of a long run also helps.

Frequently asked questions

Do fibreglass posts need insulators?
No, fibreglass does not conduct electricity. You attach the conductor directly to the post with clips. Just make sure the clips hold well and the conductor cannot slip down to the ground.

Do fibreglass posts splinter over time?
After many years in the sun, the surface can become rough and release fine fibres. Wear gloves when you move them. Replace cracked or frayed posts so that neither animals nor people get hurt.

How do I get fibreglass posts into hard ground?
Posts with a metal tip are the easiest. In very firm ground, make a pilot hole with an iron bar. Never hit the fibreglass directly with a metal hammer; use a plastic mallet instead.
