GB/T Q460NH Corten Steel

 

 

 

 

Unlike regular steel, GB/T Q460NH Corten Steel grows its own rust armor-a dense, protective layer that stops corrosion without paint. Think of it as the "low-maintenance workhorse" for tough environments.

 

 

Engineers Choose Q460NH Because:
🔥 Stronger Than Standard Corten – 460 MPa yield strength (vs. 355/415 MPa grades).
💰 Cost Killer – No painting, no coatings, no yearly touch-ups.
🏗️ Handles Heavy Loads – Ideal for bridges, towers, and industrial frames.
🌿 Eco-Friendly – No toxic paint runoff, just natural rust protection.

Where Do You Use Q460NH? (Real Industrial Jobs)

Mining & Heavy Equipment – Conveyor supports, crusher frames (handles dust + moisture).

Highway Sign Gantries – No rust streaks, no repainting every 5 years.

Power Plant Structures – Resistant to coal dust and acidic rain.

Railway Bridges – Strong enough for heavy train loads, lazy about maintenance.

Industrial Walkways & Staircases – Safety + durability without slippery paint coatings.

Why Engineers Pick Q460NH Over Other Steels

✔ "Forget About It" Durability – Install it, let it rust gracefully, and focus on other problems.
✔ Stronger Than Q355NH/Q415NH – When your project needs extra muscle.
✔ Faster Construction – Skip painting steps-fabricate and erect immediately.
✔ Proven in China's Worst Weather – From frozen Harbin to humid Guangdong.
