Trade Services
  1. Customized Solutions
    Based on industry experience and customer needs analysis, provide matching solution suggestions such as material selection (carbon steel/alloy steel/stainless steel), specification matching (wall thickness/pressure rating), and application scenario optimization (petroleum/chemical/nuclear power).
  2. Global Logistics
    Integrate the international logistics network (sea freight/air freight/land transportation), and provide a real-time cargo tracking system (GPS positioning + customs clearance progress).
  3. Inventory Optimization
    Based on industry data analysis, dynamically adjust inventory classification (material type/dimension/regional warehouse), implement Just-in-Time (JIT) supply chain management, and reduce the risk of slow sales.
  4. Compliance Certification
    Assist in providing international certification documents such as ISO, ASTM, API, etc., to ensure that products meet the access requirements of the target market.
  5. End-to-End Tracking
    Provide full life cycle services from order confirmation to after-sales support, and offer technical consultation for installation guidance throughout the whole process.
 
Processing Services
  1. Custom Cutting
    Support cutting by laser, plasma, sawing machine, and self-propelled cutting machine to meet different dimensional requirements (such as fixed length, multiple length), and provide bevel processing services.
  2. Forming
    Provide elbow bending, flaring, and necking processing.
  3. Surface Treatment
    Provide surface treatment methods such as pickling, phosphating, polishing, sandblasting, painting, coating, galvanizing, and buffing.
  4. Machining
    Provide threading, chamfering, and drilling processing.
 
Quality Inspection
      Provide third-party inspection reports (such as chemical composition analysis, mechanical properties, UT flaw detection) to ensure that products meet the standards.
