Sandwich panels for food processing plants

Sandwich panels in food processing plants are standard construction for walls and ceilings in slaughterhouses, dairies, breweries, bakery factories, beverage bottling, fruit and vegetable processors. Unlike panels for common industrial construction, here the requirement is specific: internal face in stainless steel or painted steel with sanitary finish (rounded corners, no visible rivets, smooth surface), insulating core compatible with fire class B-s1,d0, compliance with sanitary auditing (SIF in Brazil, USDA in US, EU 852/2004).

Sandwich panels with PIR core (with structural PU adhesive) are modern standard in exporting slaughterhouses. PIR delivers thermal insulation superior to EPS and better fire class, and PU adhesive guarantees face-core structural adhesion for decades without delamination. Panel failure in meat plant cold room is serious — cross-contamination, temperature loss, potential sanitary closure.
