By using several  lengths of girders, the boarding can be assembled, every certain small module. This system is cheap and can be  fitted to every architectural form. The R24 girder is reinforced at the ends, what lets on holding out of elements. The system has such an  advantage, that it shortens the assembly time, and his elements can be used many times. 

Together with the accessories-bumper blocks, gliding angles etc., the system is used as the tangent-balance boarding, the gliding boarding or the one-sided boarding.

The R24 girder of the height 24 cm shows the optimal relation of its own height to its own statical values, what characterizes it as the ideal storage- element of the wall boarding.
