Precision Engineered. Reliably Supplied.
Advanced Stainless Solutions for Demanding Industries
Founded in 2000, Baoyi specializes in High-Precision Stainless Steel Strips and Sheets for the medical, Automobile, and electronics industries. We deliver ultra-tight tolerances (±0.005mm in thickness and 0.05mm in width), advanced tempers (up to 490 HV), and non-magnetic alloys (permeability <1.005) through proprietary processes like BA temper rolling and oscillating winding.
With ISO9001:2015 Certified Production and 50,000+ tons annual capacity, our products meet ASTM/JIS/GB standards with full traceability. Our 10+ strategic stock hubs enable 24-hour emergency slit-to-size service and customized VMI/JIT solutions, ensuring agile supply chain integration for global partners.
Trusted by manufacturers requiring zero-defect quality, we solve complex stamping and corrosion challenges with technical mastery across 200/300/400 series stainless steel alloys.
Our comprehensive range of ASTM/JIS-compliant grades (200/300/400 series) delivers optimal corrosion resistance, formability, and thermal stability for medical, automotive, and architectural applications.
Custom-tempered strips (1/4H to EH) achieving up to 490 HV hardness for springs, connectors, and wear-resistant components requiring exceptional durability and fatigue resistance.
Cold-rolled coils, sheets and plates with tolerances to ±0.01mm and BA/2B/No.8 surfaces for electronics, precision instruments, and high-visibility consumer products.
Hot-rolled plates and coils with scale-free surfaces and consistent thickness for construction, industrial equipment, and fabrication requiring robust material performance.
Our production strategy is built on a foundation of application-specific equipment allocation. This means we match each production order to the machine best calibrated for its specific material parameters. Our facility integrates over 20 production lines of:
Precision Slitting Lines for burr-free edges and exact width tolerances.
Leveling & Cut-to-Length Lines that produce perfectly flat blanks with uniform length.
Edge Grinding Machines for smooth, prepared edges to enhance formability.
This tailored approach ensures consistent quality and strict adherence to the tight tolerances required by high-tech industries.
Our manufacturing excellence is powered by a dedicated team of over 50 engineers and skilled technicians. Led by a Chief Engineer with 31 years of industry experience, our team includes four Senior Engineers (15+ years each) and eight Intermediate Engineers (8+ years each).
This multi-level expertise ensures rigorous oversight throughout production. Our technicians receive professional training, embodying a craftsman’s spirit with an uncompromising focus on precision and quality control.
Stainless steel prices defy weak demand logic, remaining firm due to strong cost support, tight spot supply, and supply fears driven by Indonesian policy shifts.
