Corten Steel Plate 6mm - Weathering Steel Sheet for Architectural Cladding

Corten steel plate 6mm represents a specialized weathering steel product that develops a protective rust-like appearance while maintaining structural integrity. This atmospheric corrosion-resistant steel finds extensive application in architectural facades, outdoor sculptures, and industrial structures where both aesthetic appeal and long-term durability are paramount. Manufactured to meet ASTM A588 and EN 10025-5 specifications, this 6mm thickness option delivers an optimal balance between formability and load-bearing capacity for designers, contractors, and fabricators seeking cost-effective solutions for exposed environments.

What is Corten Steel Plate 6mm?

Corten steel plate 6mm is a high-strength, low-alloy structural steel that forms a stable rust-like coating when exposed to atmospheric conditions, eliminating the need for painting. The 6mm thickness specification provides sufficient rigidity for cladding panels while remaining lightweight enough for efficient installation. This weathering steel contains copper, chromium, and nickel alloying elements that create a dense oxide layer, protecting the underlying metal from progressive corrosion penetration.

Corten Steel Plate 6mm Technical Specifications

The material complies with ASTM A588 Grade B requirements, featuring a minimum yield strength of 345 MPa and tensile strength ranging from 485-620 MPa. Chemical composition includes carbon content of 0.19% maximum, manganese 0.80-1.25%, phosphorus 0.04% maximum, sulfur 0.05% maximum, silicon 0.30-0.65%, copper 0.25-0.40%, chromium 0.40-0.65%, and nickel 0.40% maximum. The density measures 7.85 g/cm³ at 20°C, with thermal conductivity of 54 W/m·K and coefficient of thermal expansion at 12.0 × 10⁻⁶/°C.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ is 5 metric tons for stock dimensions, though we accommodate smaller quantities for custom-cut pieces with adjusted pricing. Project-based orders exceeding 20 tons qualify for volume discounts and priority scheduling. For architectural samples, we offer 500mm × 500mm test panels to evaluate weathering characteristics before full procurement.

Do you provide material test certificates?

Yes, every shipment includes EN 10204 3.1 mill test certificates documenting heat-specific chemical composition, mechanical properties, and dimensional tolerances. Additional third-party inspection reports from SGS or Bureau Veritas can be arranged upon request. We also supply material traceability documentation linking plate identification stamps to original steel mill production records.

What is the typical delivery time?

Stock material ships within 5-7 business days after order confirmation and payment clearance. Custom cutting services require an additional 3-5 days depending on complexity and queue. International orders to major ports average 25-35 days including inland transportation, customs processing, and ocean freight. Expedited air freight options are available for urgent project requirements.

Can you cut to custom sizes?

Our CNC plasma cutting equipment handles plates up to 3000mm × 12000mm with tolerance of ±2mm. We provide straight cuts, contour cutting, hole drilling, and beveling services according to fabrication drawings. Edge preparation for welding includes options for square, single-V, and double-V groove configurations per AWS D1.1 standards. All cut edges receive deburring treatment to ensure safe handling.
