The design of Gamia Metal was made holding in consideration the installation problems;
the results is a spiral stair of different diameters, with railings always according to code
and with rise adjustement’s system which assures a climb of every height in any project.
Thanks to the above system and to pratical instructions for the assembly, the installation is a snap.
The distinctive feature of Gamia Metal is surely the design of railings. Vertical spindles
connected with the flexuous handrail assure an absolute structural rigidity.
