All U-shape staircases are made with a steel construction. Steel construction can be as thin as 20 centimetres or can be from a solid massive steel. We usually make the staircases from oak, but it can also be made from ash, plywood, mahogany or as you prefer. All of our staircases and metal construction can be painted in your desired colour. And all the railings and handrails can be made upon your desires.
