Hemaokang Steel (Shandong) Co., Ltd., established in 2025 with an annual export value between US$50 million and US$100 million, is proud to present our premium 316L Stainless Steel Coil 1.5mm Thick 1500mm Width BA Surface. As a trusted supplier serving markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, we combine rigorous quality control with competitive pricing. Each coil is supplied with a Mill Test Report to ensure full traceability and compliance with international standards, making it an ideal choice for demanding industrial applications.
Our 316L stainless steel coil is manufactured using advanced bright annealing (BA) technology, resulting in a smooth, reflective surface that enhances aesthetic appeal and simplifies cleaning. The 1.5mm thickness and 1500mm width offer excellent balance between strength and workability, suitable for forming, welding, and fabrication. The low carbon content of 316L (max 0.03%) minimizes carbide precipitation during welding, providing superior corrosion resistance in harsh environments such as chemical tanks, marine equipment, and food processing lines.
Key Product Features & Specifications
- Superior Corrosion Resistance: 316L offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich environments.
- BA Surface Finish: Bright annealed surface provides a mirror-like appearance, high reflectivity, and low surface roughness (Ra ≤ 0.5 μm), ideal for sanitary and decorative applications.
- Precise Dimensional Tolerances: Thickness tolerance: ±0.05mm; Width tolerance: ±1mm; Ensures consistent performance in automated production lines.
- Enhanced Weldability: Low carbon content reduces the risk of intergranular corrosion, making it suitable for heavy welding without post-weld heat treatment.
- Mill Test Report Included: Each coil is accompanied by a certified mill test certificate (MTC) detailing chemical composition, mechanical properties, and dimensional verification.
- ISO9001 Quality Management: Our production facility is ISO9001:2025 certified, ensuring strict process control and consistent product quality.

The combination of 316L material and BA surface makes this coil particularly valuable for industries requiring both corrosion resistance and visual appeal. In food processing, the bright surface facilitates easy cleaning and prevents bacterial growth. In pharmaceutical manufacturing, the low carbon content ensures no contamination during sterilization. For architectural applications, the reflective finish adds a modern touch while maintaining durability in coastal environments.
We understand that consistent quality is critical for your production. That is why every coil undergoes thorough inspection including thickness measurement, surface defect detection, and mechanical testing. The included Mill Test Report provides full transparency, allowing your engineers to verify compliance with project specifications. Our packaging is designed to protect the BA surface during transit, using interleaving paper and anti-rust coating when required.

Frequently Asked Questions
-
Q: What is the difference between 316 and 316L stainless steel?
A: 316L has a lower carbon content (max 0.03%) compared to 316 (max 0.08%). This reduces the risk of carbide precipitation during welding, making 316L more suitable for heavy welding applications and environments where corrosion resistance is critical. -
Q: Is the BA surface finish suitable for food contact surfaces?
A: Yes, the BA surface is bright, smooth, and easy to clean, meeting hygiene standards for food processing equipment. However, please verify local regulations for specific applications. -
Q: Do you provide the Mill Test Report with every coil?
A: Absolutely. Every coil shipped includes a Mill Test Report (MTR) that lists chemical composition, mechanical properties, and dimensional results. This ensures full traceability to the original heat. -
Q: Can this coil be used for seawater applications?
A: 316L offers good resistance to chloride-induced corrosion and is commonly used in marine environments. However, for continuous immersion in seawater, we recommend consulting with a corrosion engineer as performance may vary based on conditions. -
Q: What is the typical lead time for this product?
A: For standard sizes (1.5mm x 1500mm), lead time is approximately 15–25 working days after order confirmation, depending on quantity. We can expedite for urgent orders subject to availability. -
Q: How is the coil packaged to protect the BA surface?
A: We use interleaving kraft paper between layers, plus a protective polyethylene wrap. For export, coils are steel-strapped and placed on wooden pallets or in containers with proper cushioning to prevent scratches. -
Q: Do you offer slitting services to cut the coil into narrower widths?
A: Yes, we can slit the 1500mm master coil into custom widths (e.g., 500mm, 1000mm) with clean edges. Please specify your required width when placing the order. -
Q: Can I get a sample before placing a bulk order?
A: Certainly. We provide small samples (e.g., A4 size) for evaluation. The sample cost is negotiable, and we offer free samples for qualified inquiries. Please contact our sales team for details.
