The high-tech home design needs material or elements that can support its theme. The unproper choice of home material or element can make your home concept get confuse. Here is a new model of steel stairs for your modern or high-tech home design. With triangle cavity-ladder-step which is arranged not in a stack, this model look more artistic and interesting as well as deferent from circle staircase. The steel material of the core structure and balustrade steel cable, make this staircase style look so frail, thin and light in weight. So the concept of this style can be called “frail but strong”. I Hope it will inspire you.
