What's in the box?

1 Exterior Zink staircase - comprising, 1 landing, 12 rises (13 rises/treads in total), center column and handrail, together with all the fixtures and fittings (in stainless steel() required to build the stair.

Additional Items Available:


A rise consists of the tread frame, tread and balustrade. You can add up to 2 extra rises to get a maximum finished floor to floor height of 345cm.


The centre post is what the staircase hangs from. You'll need to buy an additional post if you are adding more than 1 rise. Our sales consultants will guide you further on this, together with the range of options and accessories before the order is placed with the factory.


If 1 or more rises are added to your staircase and you're ordering a 160cm diameter stair, then you'll need an additional handrail. The handrail is Moplen.

Here's an example staircase:

Say your finished floor to floor height was 315cm, then you would order the following:

  • 1 Exterior Zink staircase
  • 1 x Extra Rises (Treads kit)
  • 1 x Extra Center Post
  • 1 x Extra Handrail (Only if you are ordering a 160cm wide staircase)

The staircase direction can be switched clockwise or anti-clockwise on the day of installation.

Technical Information:

  • Galvanised steel

Available diameter of the aperture you're building your staircase in must be an additional 5cm on the size staircase you wish to fit. I.e. if you are fitting a 120cm staircase, the diameter must be 125cm in order for the staircase to fit.
