250 Heavy Duty Series Steel Posts Brisbane & Queensland

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

The 250 Heavy Duty Series is the pinnacle of our steel post range — maximum section modulus, maximum structural capacity, and engineered for Queensland's most demanding civil and commercial retaining wall applications. Walls over 2.5m, major road and infrastructure surcharge loads, flood mitigation structures, and high-risk retaining applications all demand the 250 Series. These posts are specified exclusively by structural engineers for projects where the consequences of failure are severe. Retaining Walls Direct has supplied heavy duty civil-grade posts to Queensland engineers and contractors for many years.
