GB/T Q295NH Weathering Steel
What Makes Q295NH Weathering Steel Special
When exposed to alternating wet and dry atmospheric conditions, ordinary steel begins to rust and lose strength as corrosion penetrates deeper into the metal. Q295NH behaves differently. Thanks to the addition of small amounts of copper (Cu), chromium (Cr), nickel (Ni), and phosphorus (P), the steel develops a dense, adherent oxide layer - commonly called a patina. This layer stabilizes over time, effectively sealing the surface and preventing further rust from spreading.
As a result, Q295NH weathering steel can remain unpainted for years, even when exposed to rain, wind, and sunlight. It combines durability with low maintenance, making it a favorite among architects, engineers, and manufacturers who value both function and appearance.
