GB/T Q355NH Corten Steel
When exposed to outdoor elements, GB/T Q355NH Corten Steel forms a stable, self-protecting rust layer that actually stops further corrosion, eliminating the need for constant repainting.
Stronger than Q295NH yet more affordable than high-end grades like Q460NH, Q355NH is the most popular choice for projects where durability and value matter equally. Its signature rusty patina isn't just practical – it adds a rugged, industrial charm to structures.
