Iranian Client Procures High-Strength Stainless Steel Coils in Custom Widths with Premium Silver Finish
Published On: June 18, 2026
Project Overview
An established industrial manufacturer based in Iran placed a significant order for high-strength stainless steel coils in custom widths of 500mm, 550mm, and 580mm. The client required premium silver finish coils across specialized grades including 904L, 410, and 2205 duplex stainless steel, paired with comprehensive third-party inspection services to ensure full compliance with their demanding manufacturing specifications.
Client Background
The client is a leading industrial equipment manufacturer in Iran, serving the oil and gas, petrochemical, and heavy machinery sectors. With Iran's industrial landscape demanding materials that withstand extreme operating conditions—high temperatures, corrosive chemicals, and high-pressure environments—the client needed a reliable international supplier capable of delivering precision-grade stainless steel coils with full material traceability and mill test certification. Their procurement requirements emphasized not only material quality but also consistent dimensional accuracy across non-standard custom widths.

Key Product Highlights
- Custom Width Precision: The coils were manufactured to exact client-specified widths of 500mm, 550mm, and 580mm—non-standard dimensions that require advanced slitting accuracy and consistent edge quality across every coil.
- Premium Silver Finish: The high-aesthetic silver surface finish meets demanding visual and functional requirements for industrial equipment housing and exposed components, combining appearance with corrosion resistance.
- Specialized Grade Expertise: The order included 904L for superior acid resistance in chemical processing, 410 martensitic grade for wear-resistant applications, and 2205 duplex for high-strength chloride environments—demonstrating multi-grade sourcing capability.
- Comprehensive Inspection: Full third-party inspection services were integrated into the production process, including dimensional verification, surface quality checks, mechanical property testing, and mill test certificate issuance for complete traceability.
- Rapid Turnaround: Delivery within 7–10 working days enabled the client to maintain uninterrupted production schedules for their downstream manufacturing operations.
Quality Assurance & Certifications
Every coil shipped was accompanied by a Mill Test Certificate (MTC) covering both hot-rolled raw material and cold-rolled finished product properties. The supplier's quality management system ensured full compliance with international standards including AISI, ASTM, DIN, JIS, BS, EN, and GB. Prior to shipment, the client received free samples for independent laboratory verification, confirming chemical composition, tensile strength, and surface integrity before bulk production commenced.
Packaging & Logistics
- Export-Grade Packaging: Standard seaworthy packaging with waterproof paper layers and steel strip reinforcement, engineered to withstand long-distance maritime shipping to Iranian ports.
- Customizable Packing: Packaging solutions tailored to client specifications and transport method requirements.
- Container Optimization: Professional loading and securing processes maximize container utilization while preventing in-transit damage.
Order Execution
- Minimum Order Quantity: 1 metric ton, with complimentary sample orders accepted for pre-production quality verification
- Shipment Time: Within 7–15 working days after receipt of deposit or L/C
- Sample Service: Free samples provided for client testing, with courier costs covered by the client via DHL/FedEx/UPS account
Project Outcome
The Iranian client successfully integrated the custom-width stainless steel coils into their manufacturing lines with zero rejection rate. The precision ±0.01mm thickness tolerance eliminated the need for secondary processing, saving approximately 12% in downstream fabrication costs. The 904L coils performed flawlessly in high-acidity chemical processing equipment, while the 2205 duplex coils delivered exceptional stress corrosion cracking resistance in chloride-rich operating environments. The 410 grade coils provided the required hardness and wear resistance for mechanical component applications. The client has since expanded their procurement program to include additional grades and has initiated discussions for a long-term supply agreement covering quarterly shipments.
Why This Partnership Matters
This case highlights the strategic value of a supplier capable of delivering non-standard custom widths, specialized grades ranging from martensitic to super austenitic and duplex, and integrated quality assurance services—all within aggressive delivery timelines. For Iranian industrial manufacturers operating under international trade constraints, finding a partner who combines technical expertise with flexible supply chain solutions is essential. The successful execution of this order, from free sample verification through bulk delivery, demonstrates a proven model for high-value stainless steel trade between China and Iran, built on technical precision, quality transparency, and consistent on-time performance.
