A natural stone or artificial granite can be used for finishing stairs from reinforced concrete, as well as a tree of solid -faced rocks. One of the options is a combination of steps with an oak or maple with forged railings. Such railings made by art forging will decorate the interior and emphasize your taste. Another option for finishing the concrete staircase is the facing of the steps with artificial granite and the implementation of railing from highly alloyed steel or over -duty glass. Glass stairs came to the interiors relatively recently, but quickly gaining popularity due to their airiness and the ability to implement original design ideas.
