PROBLEM TO BE SOLVED: To lay a deformed material rail system easily, and to reduce danger of accident. SOLUTION: The deformed material rail system 1 comprises at least two deformed material rails 5, 6 extensible to each other. At least one of the deformed material rails 5, 6 has an undercut channel deformed part 19 and/or a key deformed part 15 at the end surface facing a flooring element 2. The channel deformed part 19 and/or the key deformed part 15 are formed to fit to a channel-key deformed parts 3, 4 of the flooring element 2, whereby the deformed material rails 5, 6 are joined to the flooring element 2 at the end faces by tilting, abutting and pressing the keys 4, 15 into the facing channels 3, 19.
