*The configurations available on the Oak90 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 Oak90 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 Oak90 Modular Staircase kit can be installed with a clockwise or anti-clockwise turn using the quarter turn set/s of treads. You decide when you fit the staircase!
Generally, it is best to form the opening for the staircase at least as big as the staircase layout itself.
The standard kit has 13 risers (12 treads) and the tread rise is adjustable from 186mm to 232mm, 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 3020mm (or 2850mm 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 Oak90 staircase from 180mm to 220mm (for the 700mm wide version) and from 220mm to 260mm for both the 800mm and 900mm wide version – but the UK Building Regulations require a minimum tread going of 220mm and your chosen configuration should bear this in mind.
Powder coated 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.
