Corten Steel Plate Supplier, Manufacturer & Exporter in Saudi Arabia

Q: What is corten steel plate and why is it called weathering steel?

Corten steel plate (officially COR-TEN®) is a high-strength, low-alloy steel that develops a stable, adherent rust-like surface layer — called a patina — when exposed to moisture and oxygen. This protective oxide layer, formed by the alloying elements copper, chromium, nickel, and phosphorus, bonds tightly to the steel surface and acts as a natural barrier against further corrosion. Unlike conventional rust, the corten patina does not flake or deepen, making the steel highly durable in outdoor environments without painting.

Q: What is the difference between Corten A and Corten B plate?

Corten A has a higher copper content (0.25–0.55%) and higher phosphorus, giving it better atmospheric corrosion resistance. It is preferred for architectural and decorative applications such as building facades, sculptures, and garden features. Corten B (ASTM A588) has a higher manganese content (0.80–1.25%), giving it greater structural strength and better weldability on thick sections. It is preferred for heavy structural applications including bridges, industrial structures, shipping containers, and oil & gas platforms. Both grades are available from our Saudi Arabia stock.

Q: What is the minimum thickness of corten steel plate you supply to Saudi Arabia?

We supply corten steel plates from 0.8 mm to 100 mm thickness for delivery across Saudi Arabia. The minimum thickness for structural Corten A plates is typically 1.6 mm, while ASTM A588 corten plates are available from 0.8 mm upwards. For thicker plates exceeding 50 mm, lead times may be 7–14 days subject to mill availability.

Q: Do you supply corten steel plate to Riyadh, Jeddah and Dammam?

Yes. We supply corten steel plates throughout Saudi Arabia, including Riyadh, Jeddah, Dammam, Jubail, Yanbu, Al Khobar, Mecca, Medina, Abha, Tabuk, Hail, and Jizan. We maintain stock at bonded warehouses near King Abdulaziz Port Jeddah and Dammam ports, enabling rapid dispatch across the Kingdom.

Q: What certifications do your corten steel plates carry?

All our corten steel plates are supplied with EN 10204 3.1 Mill Test Certificates (MTC) from the original steel mill, confirming chemical composition and mechanical properties. We can arrange third-party inspection and certification by SGS, Bureau Veritas (BV), Lloyd's Register, or TÜV on request. Our plates comply with ASTM A588, ASTM A242, EN 10025-5, and ASME SA588 standards.

Q: Can corten steel plate be welded?

Yes. Corten steel plate has good weldability using SMAW (Stick), GMAW (MIG/MAG), GTAW (TIG), and SAW (Submerged Arc) processes. Use matching weathering steel welding consumables (e.g. ER70S-G or proprietary weathering wire) to maintain corrosion resistance at the weld zone. Preheat requirements apply for plates above 19 mm as per ASTM A6/A6M Appendix X3. Leave weld area bare after welding — do not paint — to allow the natural patina to form across the joint.

Q: What is the corten steel plate price in Saudi Arabia?

Corten steel plate price in Saudi Arabia ranges from approximately SAR 4,500 to SAR 7,000 per metric tonne depending on grade, thickness, quantity, and delivery location. Corten B / ASTM A588 is generally the most competitively priced grade. Contact our KSA team for a formal quotation within 24 hours including freight and documentation.

We stock and supply all major corten plate grades to meet the diverse requirements of Saudi Arabia's construction and industrial sectors:

Corten A Plate
ASTM A242 / EN 10025-5 S355J0WP

Corten Steel Plate Applications in Saudi Arabia

Weathering steel plate is finding growing application across Saudi Arabia's Vision 2030-driven construction boom and expanding industrial base:

Building & Construction: Structural frames, cladding panels, and facades for commercial towers in Riyadh and Jeddah. Corten steel plate eliminates the need for repainting over the structure's lifetime, reducing maintenance costs by an estimated 30–40% versus painted carbon steel.
Oil & Gas Industry: Offshore platforms, refineries, pipelines, and petrochemical plants in Jubail and Yanbu. Corten B (ASTM A588) is specified for load-bearing elements due to its 345 MPa minimum yield strength and compatibility with Saudi Aramco structural specifications.
Bridges & Infrastructure: Pedestrian bridges, highway overpasses, and rail structures throughout the Kingdom. Corten plate's yield strength (340–355 MPa minimum) reduces required section thickness and overall structural weight in long-span applications.
Architecture & Landscaping: Feature walls, garden screens, signage, sculptures, and public art installations. The natural patina of weathering steel plate requires zero paint maintenance and develops a stable rust-brown appearance within 18–36 months — increasingly specified in Saudi Arabia's landmark architectural projects including NEOM and the Red Sea Project.
Marine & Port Facilities: Jeddah Islamic Port, Dammam King Abdulaziz Port — quay walls and marine structures in splash-zone and atmospheric exposure conditions. Note: corten plate is not recommended for continuous saltwater immersion; design drainage to allow wet–dry cycling for patina stability.
Containers & Storage: Shipping containers, storage tanks, industrial hoppers, rail wagons and freight cars. The self-forming patina eliminates container repaint cycles, reducing maintenance overheads significantly over a 20-year asset life.
Power & Utilities: Transmission towers, substation structures, wind turbine foundations and towers. Corten plate's resistance to atmospheric corrosion is particularly valuable in Saudi Arabia's high-UV coastal and desert environments where conventional coatings degrade rapidly.
Interior Design: Feature walls, partition screens, furniture, and decorative panels in hospitality and retail. In interior applications not exposed to weather, an accelerated patina (pre-rusted) finish is available from our fabrication partners in Riyadh and Dammam.

Why Corten Steel Plate is Ideal for Saudi Arabia

Saudi Arabia's climate and industrial environment make weathering steel plate a highly cost-effective choice:

No Painting Required:The self-forming rust patina eliminates painting and coating costs — significant savings in Saudi Arabia's extreme UV environment where conventional coatings degrade 2–3× faster than in temperate climates.
Lower Lifecycle Costs:Corten plate requires no periodic repainting, reducing maintenance costs by up to 50% over 25 years compared to conventional painted mild steel. In Saudi Arabia's arid desert zones, the dry climate can extend maintenance intervals even further.
High Structural Strength:With minimum yield strength of 345 MPa, corten plate offers greater strength per unit weight than conventional structural steel, enabling lighter and more economical designs.
Vision 2030 Aesthetic:The distinctive amber-rust patina is increasingly specified in Saudi Arabia's landmark architectural and public realm projects, including NEOM, the Red Sea Project, and Diriyah Gate. Architects and landscape designers value its evolving appearance.
Weldable & Formable:Corten steel plate can be welded, cut, and formed using standard techniques. Use matching weathering steel consumables at the weld zone to ensure patina continuity. Custom fabrication available at our partner workshops in Riyadh and Dammam.
Certified & Documented:Every plate is supplied with full mill test certification, chemical analysis, and mechanical test reports compliant with ASTM, EN, and Saudi Aramco specifications. Third-party inspection by SGS, Bureau Veritas, or TÜV available on request.
Patina Development Timeline:Initial surface rust appears within 1–3 weeks of outdoor exposure in KSA. The stable, protective oxide patina forms over 18–36 months. In Saudi Arabia's low-humidity desert climate, consider periodic misting for sheltered corten elements to accelerate patina development. Initial rust run-off may occur for the first 6–12 months — design drainage accordingly.
