Hereby the boarders of feasibility are being increased further with the purpose to provide clients with special requirements the desired design staircase and at the same time supplying the modern architecture with new and never seen before impressions. Concrete is a material with a very long tradition in the stair industry. What Siller has done is to mix up the traditional material concrete with the modern ideas of stair building nowadays. The concrete look in combination with glass results in a minimalistic modern design which is simply improving the live experience of people living and moving in the surrounding space. And one could say this is the third purpose of Siller stairs, to enhance the live experience of the people living with such amazing design elements. The newest stair innovation is the self supporting “High-Tech Concrete” stair. By using different artificial materials and fiber in the right combination the concrete gets the desired strength to build self supporting steps up to 1500mm wide and only 60 to 100mm thick. Also the fixation at the wall side is tricky and was realized with a custom made steel structure hidden behind a tinted glass wall. With innovation and new ideas Siller continues to increase his brand awareness on the international market with the aim to become one of the most important global payers in the stair industry.
