FIELD: panel structures, particularly used in safes and enclosing structures for sales registers and depositories. ^ SUBSTANCE: panel comprises metal walls, frame made as at least double-layered grid of longitudinal members and filler plates of impact-resistant crack-resistant heat-insulation material. The plates are arranged at least in some cells defined by longitudinal frame members. Longitudinal frame members are formed of shaped steel-rolled stock and/or of steel roll-formed shapes having angular, channel, I-shaped or Z-shaped cross-sections. End surfaces of filler plate ends abut longitudinal member flanges, which are perpendicular to metal walls. Filler plates are connected to flanges, which are parallel to metal walls by peripheral plate planes. ^ EFFECT: reduced metal consumption due to reduced weight along with maintaining high strength properties and increased breaking-in resistance. ^ 8 cl, 7 dwg |
