Description
The Jack Zinc staircase is designed for exterior use with robust manufacture and hot galvanised steel for the treads, spine and balustrade. The Jack Zinc Modular Staircase is a clever design with a central interlocking spine which can provide a straight or L-shaped staircase. There are two versions for the L-shaped format, one with winder treads to make the quarter turn, and one with a quarter landing platform tread. The Jack Zinc modular staircase is also available in two widths to suit every project – 800mm, and 900mm.
Just choose the format for your project (straight or L from either of the two options), the right width and then it’s as easy as that!

*The configurations available on the Jack Zinc Modular Staircase are designed to satisfy most European regulations. However, please check with your local Building Control that your chosen configuration is acceptable to them. Please contact us if you would like further advice.
Please note that the Jack Zinc Modular staircase is made in Italy and some of the suggested configurations may be outside of the UK Building Regulations. If you have any queries on this, please do not hesitate to contact us for advice.
The standard kit has 13 risers (12 treads) and the tread rise is adjustable from 180mm to 235mm, although UK regulations have a maximum tread rise of 220mm. This means that the standard kit will suit floor to floor heights of up to 3025mm (or 2860mm to comply with UK Building Regulations for maximum tread rise). If your floor to floor height is higher than this, you simply need to add additional tread kits as required. If your floor to floor height is lower than this, you use less treads.
The individual tread rise and going is achieved by adjusting the central tread support modules to provide your overall correct staircase height. These are supplied in the kit, together with all fixings and fittings required plus clear installation instructions and an installation DVD!
The going or depth of the treads is adjustable on the Jack Zinc staircase from 200mm to 230mm (for the 800mm wide version) and from 220mm to 250mm for the 900mm wide version – but the UK Building Regulations require a minimum tread going of 220mm and your chosen configuration should bear this in mind.
Galvanised steel riserbars are available as an accessory kit to fit between the open treads to satisfy the requirement for the gap to be less than 100mm. Matching stairwell balustrade is also available and you’ll find more details on the Accessories pages.

Layout Options
The Jack Zinc Exterior staircase can be installed in a straight flight or with a quarter turn. The quarter turn can be formed by either using a set of winder treads or using a quarter landing tread and you can drop the quarter turn anywhere in the run of the staircase. There is also an optional 110cm landing platform for added versatility. You will find full details in the Accessories pages.
