What's the price difference between heavy melting steel and light structural steel scrap in the Australian market?
Short answer: Heavy melting steel (HMS) — thick, dense steel pieces — typically prices higher per tonne than light structural steel, which is thinner-gauge and more prone to rust. The grading distinction is about how efficiently a mill can melt and process the material, and applies consistently across Australian buyers even though exact rates move with the export scrap price, which Australia is heavily exposed to given its steel export markets.

Heavy melting steel refers to thick-gauge, dense, mill-ready steel pieces requiring minimal further processing. Light structural steel — angle iron, light beams, sheet offcuts — is thinner, less dense, and more prone to rust, which is why it commonly grades and prices below HMS.
Why Australian pricing tracks export markets closely
Australia exports a meaningful share of its processed ferrous scrap, so local buyer pricing tends to move with international scrap and steel-making demand rather than being purely domestic — this is part of why quoted rates can shift noticeably even without any local supply change.
What determines your grade
Ask the buyer their specific thickness and size thresholds for HMS versus light structural, since this varies between yards, and check your material against it rather than assuming.
How ScrapTrade Makes This Easier
Describing your load’s general thickness and piece type in a ScrapTrade listing helps buyers quote the correct grade upfront rather than defaulting to a conservative estimate.
