Purchasing Selection Tips

1. Core Screening Factors

Compliance: Verify alignment with standards like ASTM A480, GB/T 3280, or EN 10088-2. Request official certifications and third-party reports from SGS or BV.

Processing Precision: Focus on dimensional tolerance and surface roughness data. For steel structure processing, prioritize suppliers offering slitting and flattening services to cut on-site work.

Anti-Corrosion Performance: For coastal/humid projects, select products passing 800+ hour salt spray tests to ensure long-term durability.

2. Common Pitfall Avoidance

Avoid suppliers unable to provide complete MTC certification, as this may lead to project acceptance compliance risks. Be cautious of overly low-priced products, which often compromise material purity and precision, increasing long-term maintenance costs.

Do not overlook delivery cycle guarantees. For time-sensitive projects, confirm production capacity and inventory levels to prevent delays.

3. Quick Decision Method

For high-end facades: Prioritize suppliers with high surface precision and international compliance. For steel structure processing: Choose suppliers offering integrated processing services. For export projects: Select suppliers with rich export experience and customs support.
