FAQs
Q: What types and standards of stainless steel do you mainly supply?
A: We mainly supply a wide range of stainless steel products including stainless steel pipes/tubes (seamless and welded), plates, coils, strips, and bars. Common grades include 304/L, 316/L, 321, 310, 410, 430, 2205 (Duplex), and 904L, which are widely used in construction, chemical processing, food equipment, and marine engineering. All stainless steel products comply with international standards such as ASTM, JIS, and EN. We can also provide corresponding material test certificates (MTC) and support customized specifications according to customer project requirements.
Q: Can you provide special specifications or non-standard customization? For example, extra-wide plates or pipes with specific wall thicknesses?
A: Of course. One of our advantages is our flexible customization capabilities. We can provide customized size cutting, special thicknesses, and special surface treatments (such as 2B, BA, No.4 brushed finish, mirror finish) based on your drawings or requirements. Whether it's a small trial order or a large-volume purchase, we can meet your needs.
Q: How do you guarantee the quality and consistency of materials? Do you have quality certifications?
A: Quality is our lifeline. We use direct supply from large steel mills to ensure material traceability. Each shipment comes with a Material Quality Certificate (MTC). We have our own quality control team that conducts random checks on material composition, dimensional tolerances, surface finish, and mechanical properties. Our factory is also ISO 9001:2015 quality management system certified.
Q: What are your delivery times and logistics solutions for overseas customers?
A: For standard-specification in-stock products, we can complete preparation and shipment within 7-14 days. Delivery times for customized products will be determined through negotiation based on the specific process. We have established international logistics partners who can arrange full container load (FCL), less-than-container load (LCL), or air freight according to your needs, and provide various trade terms such as EXW, FOB, CIF, and DDP, with door-to-door service.
Q: As a new customer, how do I begin cooperation? Can you provide samples for testing?
A: The cooperation process is very smooth: 1) You provide specific requirements (brand, specifications, quantity, standards); 2) We provide a quotation and technical advice; 3) After confirmation, we arrange the contract and payment; 4) Production/pickup and quality inspection; 5) Shipment and provision of documentation. We encourage sample testing. For serious customers, we can provide small-size samples to ensure that the materials fully meet your processing and application requirements.
