Aluminium vs Iron Railings — Why Aluminium is the Clear Winner
Complete comparison of aluminium and iron railings. Discover why modern builders and homeowners are switching from iron to aluminium 6063 — rust-proof, lightweight, and maintenance-free for 25+ years.
Quick Answer
Aluminium railings are 65% lighter, completely rust-proof, last 25–30 years with zero painting, and are available in unlimited colours. Iron railings rust within 2-3 years, require repainting every season, and are extremely heavy — making aluminium the clear choice for modern construction.
