Spiral by mario taepper from germany

My design is a huge spiral which has a diameter at the bottom of 3.50 meter and a total height 2.80 meter. The spiral is made out of a tube of a diameter of 50 mm and should be aluminium ( powder coated ) or carbon. The tube must be bendet . The spiral is covered from the bottom to the top with little holes for LED lamps. With all that light the spiral corresponds to a christmas tree.
