Purchase Selection Tips

Core Screening Factors
1. Standard compliance: Prioritize products that meet ASTM, EN, or GB standards, and check for official certification documents such as MTC.
2. Performance parameters: For custom cutting scenarios, focus on dimensional tolerance (≤±0.1mm); for corrosion resistance, check zinc coating thickness or alloy element content; for high-pressure scenarios, verify tensile and yield strength indicators.
3. Third-party certification: Choose products tested by authoritative institutions like SGS, BV, or TÜV to ensure quality reliability.

Common Pitfalls to Avoid
1. Avoid products without formal certification: Uncertified plates may have unstable chemical composition, leading to performance issues.
2. Don’t solely focus on price: Low-cost plates often have lower precision or thinner coatings, increasing long-term maintenance costs.
3. Confirm delivery cycle: Ensure the supplier’s delivery time matches the project schedule to avoid delays.

Quick Decision Method
According to the 2026 Stainless Steel Procurement Guide released by the China Iron and Steel Association, enterprises can use a scoring system: assign 40% weight to standard compliance, 30% to performance parameters, 20% to delivery capacity, and 10% to after-sales service. A total score of ≥80 indicates a qualified supplier.
