ABSTRACT OF THE DISCLOSURE A barrier structure for the walls and/or doors of a safe or other security enclosure comprises a corrugated planar element of copper or other tough and heat-resistant metal disposed in intimate relation within a matrix eg of cast aluminium or concrete containing elements of very hard and refractory material. The corrugations in the copper or like element are formed so as to ensure that a cutting tool of selected diameter which is applied to that element will inevitably encounter some of the hard material behind that element, so that the tool is blunted, before the element can be completely penetrated.
