On-site failures with stainless steel cleanroom panels​ rarely start as material defects alone. Most trace back to incorrect grade selection, untreated cut edges, carbon-steel cross-contamination, poor sealant compatibility, weld passivation skip, film left too long, core delamination, and weak joint sealing that later fails cleanroom acceptance. This FAQ gives procurement engineers, cleanroom contractors and pharma/food GMP builders a fast diagnostic checklist for stainless steel cleanroom panels, with repair priorities aligned to medical, lab, food and pharmaceutical enclosures.

This FAQ guide addresses common questions about stainless steel cleanroom panel core materials – rock wool, magnesium-oxide (MgO), and aluminum honeycomb. It covers selection criteria for hospitals, food factories, cleanrooms, and modular projects, with region-specific advice for South China's humid climate. Based on SAMZOON's practical project experience, it offers actionable recommendations for engineering companies and procurement professionals.
