150 Heavy Duty Series Steel Posts Brisbane & Queensland

150 Heavy Duty Series Steel Posts for Retaining Walls — Brisbane & Queensland

When standard 100 Series posts aren't enough — for tall walls, heavy surcharge loads, commercial projects, or engineer-specified designs — the 150 Heavy Duty Series delivers the structural capacity required. Retaining Walls Direct has supplied 150 Series posts to engineers, builders, and commercial contractors across QLD for many years.

• Accepts 75mm and 100mm concrete sleepers
• Suitable for walls from 1.5m to 2.0m+ (engineer certification required above 1.0m in QLD)
