Big steel for Brisbane projects
Very few Queensland suppliers hold universal columns above 200 UC. Our fixed-length 200 UC and 250 UC stock sits in Brisbane for quick delivery, and anything outside those lengths or sizes is cut to the nearest 100 mm in Melbourne and galvanised before freight. Commercial schedules, welded fence brackets and custom corner posts are all quoted from your drawings.

Frequently asked questions
Which sizes are in stock in Queensland?
200 UC 46 and 250 UC 72 galvanised posts are stocked in QLD at fixed lengths. All other super heavy duty sizes are cut to order in Melbourne and freighted up, which adds about one week of cutting and galvanising plus around 3 days transit.
Why are there no prices on the larger sizes?
Sections above 200 UC are cut from full-length stock, so the price depends on your cut list: the number of posts, lengths and offcut efficiency. Quoting case by case keeps the price sharp; most quotes are returned the same day.
Are the posts galvanised?
Yes. Every post is hot-dip galvanised after cutting. Watch for cheaper quotes on raw (non-galvanised) steel: buried steel without galvanising will not last in retaining wall service.
