Corner Posts

Corner posts are hot dip galvanised steel posts designed for the point where retaining walls change direction. One corner post takes sleepers from both runs, so the corner stays tight. Choose the series and length from the options on the product and check stock before you order.

How to plan a corner.

Set out the corner first, because every other post is measured from it. Use marking paint on the ground and check the angle before you dig. A 90 degree corner is the standard.

Post size, length and footing depth come from your wall design. In Queensland, walls over 1m high generally need an engineer's design and council approval.

A corner post is a steel post with channels facing two directions. It joins two runs of sleepers at a corner in place of two separate end posts.

How many corner posts do I need?

The range is built around 90 degrees. Contact us for other angles and we will check with the supplier.
