At both sides the steel balustrade stringers were fixed at the existing concrete stairs. Beside their guarding function the stringers are used to mask the slab edges as well as to connect the stair cover. 

  • Thickness of the steel balustrade stringers: approx. 10-12 mm or according to structural requirements
  • Height of the steel balustrade stringers: approx. 1400 mm or approx. 1020 mm above finished floor, continued downwards approx. 350-400 mm
  • Flight of the steel balustrade stringers: approx. 48 running meters at both sides of the concrete stairs
