  1. Excellent Mechanical Properties

  • High strength and toughness for harsh working conditions

  • Uniform thickness (tolerance ±0.05mm) and flatness, reducing processing waste

  1. Flexible Customization

  • Tailor-made specifications (thickness, width, grade, surface) to match your exact needs

  • Small batch orders (≥1 ton) accepted for trial projects

  1. Cost-Effective & Efficient Supply

  • Factory direct sales: No middlemen, competitive prices

  • Fast delivery: 7-15 days for standard orders; 20-30 days for customized orders

  • Global logistics support: Partner with top freight forwarders for safe & on-time delivery (FOB Shanghai, CIF worldwide ports)
