Q295NH Corten Steel Pipe

Q295NH is a low-alloy structural weathering steel developed according to GB/T 4171, offering excellent corrosion resistance, good formability, and a naturally developing protective rust layer in atmospheric environments. As a Corten steel equivalent, Q295NH is ideal for architectural and civil engineering applications requiring a natural aesthetic and extended service life without painting.

This steel is especially popular in landscape design, urban projects, and decorative steelwork, where both appearance and durability are essential.
