Ensuring Excellence in Pre-Shipment Inspection for PPGI Coils

Date:2025-06-25

For the past four years, we have been proudly supplying high-quality PPGI coils to our valued client in Sohar, Oman.

This long-term partnership began when the customer turned to us after experiencing inconsistencies in product dimensions from their previous supplier. Recognizing the critical importance of precision in the steel industry, we have consistently delivered coils that meet exact specifications, earning their trust and establishing a reliable monthly order cycle.

PPGI coil

Commitment to Precision
Understanding the client’s historical challenges, we prioritize meticulous production and inspection processes to ensure every PPGI coil shipped to Sohar adheres to their required dimensions and quality standards. Our approach includes:
Strict Production Controls: Raw materials and manufacturing parameters are verified against customer specifications before production begins.
Multi-Stage Inspections: Dimensional checks (width, thickness, coating weight) and surface quality assessments are conducted at critical stages—post-rolling, coating, and slitting.
Pre-Shipment Verification: A final 100% inspection guarantees compliance with tolerances (e.g., ±0.1mm for thickness, ±2mm for width) and packaging integrity.

Quality Assurance Tools
Laser micrometers and coating gauges for accuracy.
Third-party lab testing for corrosion resistance (ASTM standards).
Digital documentation with inspection reports for traceability.

Sustaining Trust Through Consistency
The client’s shift to our services was driven by their need for reliability. By embedding "zero-defect" objectives into our workflow and maintaining transparent communication, we have not only resolved their initial concerns but also fostered a partnership that thrives on mutual growth.
