Why choose ASTA stairs for interiors?

  • Modular construction: Allows precise adjustment of the number of steps to the size of the room, enabling heights from 340 mm to 3,800 mm.
  • Usable width of 700 mm and  900 mm: Ensures comfortable use, even in narrow spaces.
  • Variety of finishes: Various types of steps are available for indoor stairs, including glued beech boards, which are an excellent fit for interiors.
  • Aesthetic railings: A choice of several railing types is available, including infill with steel cables or tubes, which add lightness and a modern look to the structure.
  • Durability and safety: Made of high-quality S355JR and S235JR steel, the stairs are resistant to mechanical damage and corrosion thanks to anti-corrosion coatings such as galvanic zinc coating and powder coating.
