  • What is your minimum order quantity (MOQ)?

    MOQ varies depending on the product type, material, and specifications. Standard products have a defined MOQ, while custom orders offer more flexibility. We will provide the most cost-effective solution based on your needs.
  • What quality certifications does your company hold?

    Our production system complies with industry standards, and our products can be manufactured to meet various international and national standards. For specific certification details, please contact our sales team for the latest information.
  • How do you ensure product quality?

    We implement strict quality control throughout the entire process, from raw material inspection to finished product delivery. For stainless steel and carbon steel materials, we conduct composition and mechanical property tests. Advanced testing equipment (e.g., hardness testers, tensile testing machines) is used during production to ensure every batch meets standards and customer expectations.
  • How do I choose between stainless steel and carbon steel?

    The choice depends on the application environment:
    Stainless Steel: Recommended for environments requiring corrosion resistance and rust prevention, such as food machinery, chemical equipment, outdoor structures, or coastal areas. Common grades include 304 (general purpose) and 316 (enhanced acid/alkali resistance).
    Carbon Steel: Ideal for applications where high strength and cost-effectiveness are priorities, and where the environment is relatively dry, such as steel structures and heavy machinery. Surface treatments can improve its rust resistance.
    Our engineering team is happy to provide professional material selection advice.
  • Do you offer custom manufacturing (OEM/ODM)?

    Customization is one of our core strengths. We can develop products according to your drawings, specifications (such as ASTM, DIN, ISO, GB), or specific application requirements, with options for material selection (stainless steel or carbon steel), dimensions, strength grades, and surface treatments (e.g., galvanizing, Dacromet, passivation).
