Corten Steel
Corten steel materials include a wide range of grades across different standards:
EN grades: S355J2W, S355J0WP, S235J2W
ASTM grades: A588, A242, A606 Type 4
Other standards: SPA-H, Q355NH, Q235NH
Corten steel buildings rely on a range of standardized weathering steel grades to achieve durability and design performance.
Corten metal cladding relies on a self-forming protective oxide layer rather than external coatings. This layer is created through a controlled oxidation process driven by alloy elements and environmental exposure.
14 gauge Corten steel (approximately 1.9 mm thick) is one of the most practical and widely used sheet thicknesses.
Corten steel plates are available in a broad thickness range from 0.8 mm up to 100 mm+, covering both thin sheets and heavy plates.
As a trusted tree grating supplier, Teda Ganghua combines 20 years of export experience, advanced corten steel processing equipment, skilled workers, and professional engineering support.
Corten steel tree grilles typically take about 1 to 3 months to develop visible rust color, and 3 to 6 months to achieve a stable reddish-brown finish, depending on environmental conditions.
Corten steel garden boxes are often chosen over galvanized steel because they offer:
Self-protecting corrosion resistance through a stable rust layer
Longer service life with less maintenance
Superior aesthetic appeal for landscaping design
Better structural strength for large planter applications
Square corten steel planters are widely chosen for outdoor use because corten steel offers:
Superior corrosion resistance through a protective rust layer
Long-lasting structural performance
Low maintenance requirements
Distinctive and evolving natural appearance
Strong adaptability to outdoor environments
Corten steel beds require well-designed drainage and optional water inlet systems to ensure proper plant growth and long-term performance. With its self-protecting rust layer, corten steel offers excellent corrosion resistance in outdoor environments.
Circular Corten Steel Planters
Circular corten steel planters combine functional durability with architectural aesthetics. Through precise cutting, rolling, welding, and controlled rusting processes, they achieve both structural strength and a distinctive weathered appearance. Their versatility and long lifespan make them an ideal choice for modern landscape and urban design projects.
Extra Large Corten Steel Planters
Extra large corten steel planters require careful selection of high-quality corten steel coils or plates, with appropriate thickness and dimensions for stability and longevity. Using corten steel ensures:
Durability and weather resistance for oversized applications
Minimal maintenance thanks to the protective rust layer
Customizable sizes and shapes for any large landscaping project
