150mm Heavy-Duty C-Channel Posts for Concrete Sleeper Retaining Walls
Our 150 Series C-channel steel posts (also known as 150PFC) are engineered for terminating or changing direction in concrete sleeper retaining walls that use 150mm thick sleepers. These posts are essential for the structural integrity of the wall at its ends, transitions, or corners, where high pressure or load-bearing requirements apply.
Manufactured from structural-grade steel and hot-dip galvanized for long-lasting protection, these posts are designed to meet the demands of Brisbane’s weather conditions, soil movement, and council compliance.
Applications of 150mm C-Channel Posts
Use 150 Series C-posts for: – **Wall terminations and ends** – **Corners or angled transitions** – **Fencing points above retaining walls** – **High-load, engineer-specified retaining wall projects** – **Retaining walls over 1.2m in height**
These posts can be combined with 150mm H-beam posts for straight runs and 90°/45° corner posts for clean directional changes.
