01 / Product overview

Choosing a size: pick the wall height you are building. There's no need to work out the post length yourself.

Why reo: the welded bar locks the post into the pier, which helps on softer ground and higher walls. It follows the STA Consulting column and welded bar design.

Also order: 100PFC C posts for the ends, post caps, sleeper wedges and concrete for the piers.

In Queensland, walls over 1m high, or walls supporting a driveway, fence or building, generally need an engineered design and council approval.

Check your wall design

In Queensland, walls over 1m high, or walls supporting a load such as a driveway or building, generally need an engineer's design and council approval. Confirm sleeper and post sizes against your design before ordering.

Compare post sections

  • The number is the section's depth in millimetres. A 150UC is about 150mm deep.
  • The weight (kg/m) shows how heavy the steel is. At the same depth, heavier means thicker steel and a stronger post.
  • UC (universal column) is an H shape. It goes mid-run as a joiner, holding a sleeper on each side.
  • PFC (parallel flange channel) is a C shape. It goes at the end of a run, where the sleepers stop.
  • UB (universal beam) is an I shape, deeper than it is wide, so it is very stiff for its weight. It is used in engineered walls.
  • Every post is hot-dip galvanised.

A general guide only. Post size, spacing and footing depth depend on wall height, soil and any load behind the wall. In Queensland, walls over 1m high, or walls supporting a driveway, building or fence, generally need an engineer's design and council approval. Order the section your design specifies.

04 / Product FAQs

Before you order.

What is a 100UC reo post for a retaining wall?

A 100UC reo post is a galvanised 100UC steel H post with reinforcing bar welded to the base. The reo ties the post into its concrete pier for a stronger footing. It takes 75mm and 80mm sleepers on both sides.

How do I choose the size of a 100UC reo post?

Pick the wall height you are building, from 400mm to 2.0m. The post is supplied at the length that height needs, including the embedded section. For walls over 1m, or where the wall is engineered, confirm with your engineer.

Does a 100UC reo post replace a deeper pier?

A reo post reduces the pier depth needed in many cases but does not remove the need for a properly sized pier. Follow the design tables for your soil type.

Do I need council approval for a reo post retaining wall?

In Queensland, retaining walls over 1m in retained height generally need building approval and an engineered design. Lower walls can still need approval when they are close to a boundary or a building, support a driveway or pool, or carry a fence. Check with your council before you order.
