Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of stainless steel additives, it is recommended to prioritize confirming key technical parameters such as product thickness, surface treatment process, and corrosion resistance level to ensure compliance with specific engineering or equipment performance requirements.
  • When using stainless steel in food processing or chemical equipment, it is necessary to select the corresponding material model based on the characteristics of the medium, such as 304 or 316L, to meet different acid and alkali resistance requirements.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to balance procurement efficiency and long-term cooperation stability.
  • For the procurement of stainless steel in the field of architectural decoration, attention should be paid to the flatness and welding performance of the plates, and it is recommended to conduct a comprehensive evaluation based on the supplier's industry performance and actual case data.
