Our in-house testing laboratory and standardized quality management system verify every stage of production — from raw material inspection to finished panel performance. Key parameters tested include core density, thermal conductivity, fire rating, compressive strength, and peel strength, in line with ISO and EN standards. Every batch ships with a full inspection report, giving EPC contractors and pharmaceutical, semiconductor, and food-processing buyers traceable, verifiable quality assurance from Shandong to job sites across the Middle East, Southeast Asia, and South America.
