China aluminium extrusion output slumps as property weakness deepens, export boost fades

China's aluminium extrusion output has continued to trend lower, with the construction segment acting as a significant drag. According to Mysteel's sampled manufacturers, industry output sustained a decline from July to September 2026. Within this, construction aluminium extrusion output fell by a cumulative 21.2 per cent from early July to September, reflecting persistent weakness in traditional building demand. In contrast, industrial extrusion output declined by just 3.7 per cent over the same period, demonstrating relative resilience and providing a floor for total production.

Total aluminium extrusion output dropped 11.8 per cent from early July to September, while capacity utilization rates slid from 41.83 per cent to 36.90 per cent. The industry is operating at a low ebb overall, with more than 60 per cent of capacity sitting idle or running at low loads.

On the supply side, the "produce-to-order" model is highly pronounced, with scheduling cycles shortening. The composite lead time has been compressed from 8.63 days to 7.76 days, that is, the production pace has accelerated but order backlogs have shrunk.

Both raw material and finished goods inventories destocked in tandem: raw material stocks fell 18.7 per cent, outpacing the 15.6 per cent drop in finished goods, indicating that amid unclear demand prospects, producers have been proactively scaling back input purchases to curb operational risk. Order drawdown has remained sluggish, with outstanding orders down 11.1 per cent, underscoring feeble end-user demand recovery.
