The rise height (S) difference between the treads must be between 18-21cm. The ground (G - is the tread space for a foot) must be so that the stair is safe and good to access.ģ. See our dimension schemes on each staircase.Ģ. There must be a head room above the stair of at least 2.2 meters (preferably more) – on every tread on the way up. GOOD RULES TO REMEMBER - when you going to have a staircase:ġ. The following points can be used as a guide on how to construct a good and functional staircase. It is a good idea to take these guides into consideration when designing new interior stairs. The Building Regulations provide guidance on how staircases should be designed at common access stairways. If you are not sure on the application, please get in contact. This means you could need extra banisters and child riser bars between the treads. You should always check with your local building authority before committing to a purchase. UK building code requires staircases to comply to certain specifications, one rule is a 100mm sphere test where at no point can this pass through the staircase. ![]() Stringer: It is the centre construction that is supporting every step/tread. In our assembly instructions and dimension sheets you will find measurements on stair railing and landing banisters. It is always possible to choose a railing for the stairs or repos with vertical balusters, where the distance is a maximum of 10 cm. Landing banister: The height of our landing banister (balcony balustrade) must at least be 100 cm, and the height of our stair handrail is at least 90 cm. In all our DIMENSIONS of the staircases you will find the pitch of the staircase. It is telling how steep slope of the staircase is e.g., a space saving staircase is a more compact staircase and developed with a steeper pitch to occupy minimal space compared to a main staircase like DUBAI which have the focus on comfort. Pitch of staircase: The angle created by the line of nosing with the horizontal is known as the pitch of a stair. Handrail: Is the hand railing provided in every staircase to hold while climbing stairs. If you choose our banister named CLASSIC, you are safe and you can increase safety by choosing CLASSIC III over CLASSIC II. distance is a maximum of 10 cm to comply to code in UK. Pay attention to the distance between vertical balusters max. Stair banister: Consist of the handrail and balusters. Low rise e.g., 18 cm provides better comfort. Rise height: (S) difference between the treads must be between 18-21cm. Ground: (G - is the tread space for a foot) must be so that the stair is safe and good to access. See our dimension schemes on each staircase. Headroom: There must be a head room above the stair of at least 2.2 meters (preferably more) – on every tread on the way up. Tread width will tell how wide the treads are, Riser bars are designed to fit horizontally between the treads of an open-tread staircase, they close the gap between the treads to less than 10cm which is also a requirement for UK building regulations.Treads: They are also named steps from time to time but in connection with a staircase that are named treads. ![]() ![]() You may also want to consider our riser bars kits? These are also available below. The pack also includes 2 extra balusters for the top platform along with 1 extra for each tread (11 pcs.). If you are looking to install as a primary staircase compliant with UK building regulations, you will need to ensure the gap is no wider than 10 cm. Adding 1 pack will give 1 extra baluster per tread on a 12 tread staircase and can be used with our Calgary & Montréal spiral staircases ranges.Īdding one pack will bring the space between balusters on each tread from 20,5 cm to 9.05 cm on the 120 diameter Calgary, and from 23.5 cm to 10.5 cm on the 140 diameter. The middle banister pack can be added to your DOLLE spiral staircase to reduce the space between the main balusters.
