Corten Steel Plate - Application: Construction

Corten steel, also known as weathering steel, is a group of steel alloys developed to eliminate the need for painting and form a stable rust-like appearance after exposure to weather. It is commonly used in architectural, structural, and outdoor applications due to its distinctive look and long-lasting performance.

C General Description:
Material Name: Corten Steel (also known as COR-TENAR steel)
Types: Corten A (for architectural applications), Corten B (for structural applications)
Finish: Natural oxidized (rust-like patina)
Thickness Range: Typically 1.5 mm to 50 mm
Standard Sizes: 4' x 8', 5' x 10', custom sizes available
Standards: ASTM A588, ASTM A242, EN 10025-5

Key Features:
Weather Resistance: Forms a protective oxide layer (patina) that prevents further corrosion
Low Maintenance: No need for painting or frequent treatment
High Strength: Stronger than mild steel
Aesthetic Appeal: Rustic, industrial appearance that changes with time
Weldable & Formable: Can be cut, welded, and bent like conventional steel

i, Common Applications:
Architectural facades and cladding
Garden sculptures and planters
Building and bridge construction
Signage and fencing
Outdoor furniture and screens

a Mechanical Properties (Typical for Corten A):
PropertyValue
Yield Strengtha Y 345 MPa (50 ksi)
Tensile Strengtha Y 485 MPa (70 ksi)
Elongationa Y 20%
Corrosion Resistance5a 8 times higher than mild steel

i, Surface Treatment (Optional):
Pre-rusted finish (accelerated patina)
Oiled or untreated (to develop natural rust over time)
Clear sealant (to maintain current appearance)
