Q295GNH Corten Steel Pipe

Q295GNH is a Chinese standard weathering steel grade defined under GB/T 4171, known for its moderate strength and good atmospheric corrosion resistance. It is particularly suitable for lightweight structural components, architectural cladding, and garden steel projects, offering a natural rustic finish with minimal maintenance.

The alloy includes copper, phosphorus, and chromium, enabling the steel to form a stable protective patina over time, which enhances durability and visual appeal.

📌 Highlights

• Yield Strength: ≥ 295 MPa

• Tensile Strength: 430–590 MPa

• Elongation: ≥ 20%

• Excellent Workability: Cold forming, welding, cutting

• Patina Formation: Natural rust film resists further corrosion

🏗 Ideal For

• Outdoor architectural cladding and curtain walls

• Garden edging, planter boxes, corten landscape features

• Bridges, railings, and urban fixtures

• Public art and steel sculpture projects

• Low-rise structural steelwork exposed to open air

🔧 Processing & Delivery

• Supplied as: Steel plates, flat sheets, rolled coils

• Surface: Mill / rusted / oiled / blasted

• Max Thickness: Up to 100 mm

• Processing Services: Laser cutting, bending, painting (if required)

• Testing: Mechanical properties, thickness, surface quality, impact (optional)

Q295GNH is the ideal material when combining cost-efficiency, weathering ability, and aesthetic finish for creative and functional steel applications.
