Metal chassis (1) for the covering or realisation of surfaces, such as floors, buildings or masonry works, comprising a plurality of ring-shaped walls (2, 2') placed side by side that develop in a tubular manner around wall axes (X) substantially parallel to each other to circumscribe chassis cavities (4, 4') and that delimit, in correspondence of at least one axial end, substantially flat wall surfaces (6) that circumscribe access openings (8) to said cavities. The invention also covers a covering or panel and a method of manufacturing the latter. |
