G350 Steel

Much like G250 steel, this mild steel is easily weldable and prone to rusting if left unpainted or untreated, yet it’s incredibly durable, offers good form ability, and provides enough give in its composition to avoid breaking or cracking in extreme conditions. G350 steel contains less than 0.2 per cent carbon (as do all ‘mild steels’), comes in thicknesses ranging from 5-300mm, and is most commonly used for the likes of general metal fabrication, high rise buildings, bridges, and storage tanks, among other applications.

At Australian Steel, we offer G350 steel that’s compliant with Australian Standard 3678, which regulates the material and welding standards of structural steel, hot-rolled plates, floor plates and slabs. If you’re looking for G350 steel or an AS36798 grade 350 equivalent for your next project, you’ll find it at Australian Steel.
