2. Conduct Trial Pours and Joint Testing

Test sample sections under actual pouring conditions:

• Check seam leakage: Acceptable limit is <0.1L/m²/hr
• Measure deflection: Should not exceed 1/400 of span length
• Evaluate surface finish: Match against F1, F2, or F3 standards as required

3. Verify Durability Claims

Ask for video evidence of repeated use cycles. Inspect wear patterns on edges, locking mechanisms, and internal coatings. Reputable suppliers will provide accelerated aging tests for polymer components.

4. Structure Payment Terms Strategically

Use milestone-based payments with at least 30% withheld until post-installation validation. Tie final disbursement to successful demolding and surface inspection results.
