Stairways

Typical stairways are manufactured from concrete of strength class C25/30; other classes of concrete are also available in case the client, or a project provided by the client, requires a different class. The breadth of an element may vary from 550 mm to 1500 mm, the height of an element is about 150-200 mm; the length depends on the number and measurements of stair treads. The total number of treads may vary from 2 units to 18 units; the breadth of treads is 250 300 mm.
