The 200 UC 46 is the maximum residential H-Beam Universal Column specification for concrete sleeper retaining walls — the correct post for walls over 1.8m, high surcharge applications (heavy vehicle loads, structures above the wall), and all engineer-specified designs requiring a 200 UC section. The 200 UC 46's exceptional section modulus handles the highest lateral earth pressures encountered in residential and light commercial retaining wall construction.
With 40+ years of hands-on retaining wall experience across Australia, we specify the 200 UC 46 for the most demanding residential applications — tall walls on reactive clay sites, driveway walls with heavy vehicle surcharge, tiered wall systems, and any engineer-specified design where structural performance is non-negotiable. All posts are hot-dip galvanised to AS/NZS 4680 and comply with AS 4678-2002 Earth Retaining Structures.
