What are Oz-Post ground anchors?

Oz-Post ground anchors are pre-fabricated galvanized steel bases designed to permanently support posts without needing to dig holes and concrete foundations. Oz-Posts are foundations used in signpost, marker post, street furniture, underground service marker, fencing, domestic and farm stockyard applications.

Why use Oz-Post?

The original system for saving time and labour when installing permanent and temporary posts. Oz-Post will save you time and money. Across all applications posts are fully recyclable, retrievable and re-useable eliminating wastage. Easily removed, an Oz-Post will not leave a hole. Oz-Posts have been impact tested, rated for horizontal loads and wind resistance and are manufactured in accordance with Australian Standards.
