Construction times are significantly reduced, a consistently high level of exposed concrete quality is guaranteed and the final assembly is simplified. Straight adjustable stair moulds pro- vide the optimal solution for every requirement. Stairs, with or without landings, are produced either overhead or standing. The following con- tinuously variable dimensions are possible: tread depth between 220 – 320 mm, riser between 150 – 220 mm and tread widths between 900 – 1,200 mm. The soffit thickness is variable. For clockwise and anticlockwise stairs, the indi- vidual steps are simply adjusted by turning. The steps can be produced with a sharp or bevelled edge, while the step shape can be rectangular or produced with an undercut. Up to 17 steps can be produced in the standard form, and up to 24 steps with an extension. Staircases are the ideal solution for extra-wide stairs with access and exit landings. 4
