UB150 is shorthand for the 150 mm universal beam family — usually written 150UB14.0 or 150UB18.0. It is one of the most useful small sections for retaining walls: deep enough to be genuinely stiff, light enough for two people to place by hand, and cheap enough that closer post spacing stays economical. The sizes in the […]
“What steel do I need for my retaining wall?” is the question we answer most often. The honest reply is that retaining wall steel is a system, not a single product: the section decides stiffness, the grade decides strength, the finish decides how long it lasts, and the spacing and footing decide whether any of […]
Whether you spell it galvanized or galvanised, the product is the same: a structural steel post dipped in molten zinc so it can sit in wet soil for decades without rusting away. Because most engineering software, imported catalogues and search habits use the American spelling, we get asked for galvanized steel retaining wall posts almost […]
250UB25 is the deep, economical option for taller sleeper retaining walls. At 248 mm deep it delivers a large section modulus about its major axis while weighing barely 26 kilograms per metre. On a long wall that difference shows up in both the steel invoice and the handling plant you need on site. The catch […]
200UB18 is one of the most cost-effective retaining wall posts on the market. At just over 18 kilograms per metre it is light enough for two people to place by hand, but 200 mm deep, which gives it real bending strength for low and mid-height sleeper walls. The trade-off is a narrower flange than a […]
Ask for retaining wall posts anywhere in Victoria and you will be quoted “galvanised H section”. It is the default for sleeper walls for good reason, but the term covers several different steel profiles with quite different capacities. Knowing which one you are actually buying protects you from both over-spending and under-building. Why the H […]
