We normally recommend avoiding square platforms as they Spiral Staircases UK Building Regulations In addition, we give you here below a reference table listing UK Building regulations. The value of risers and going have to be checked according to the building regulations of your area. Of steps will be then 11 + 1 landing platform. We can therefore have 12 risers of 225 mm each. For instance, this value has to be divided for the advised rise value which is between 220 and 240 mm. We take as example the floor to floor height of 2700 mm. Secondly, check the floor to floor measure and Spiral Staircase floor plan. Treads and Risers per 360 degrees turn Step 3. We will go for 12 as this will give us a wider center going (step of 30 degrees). On a spiral staircase drawing with a diameter of 1500 mm this chart is saying that we can have 12 or 13 steps per circle. Now that you know the spiral staircase diameter, you have to find out how many steps you need per turn of 360 degrees (the total degrees of a circle). ![]() Mm (or round diameter 1600 mm) the diameter of your staircase will be 1500 xġ500 mm (or 1500 mm diameter). If your stairwell square opening is for example 1600 x 1600 This is to be able to fit the staircase in an easy way and to allow for the hand to grab the handrail without touching the slab. Remember that the spiral staircase diameter will have to be 100 mm smaller than the ceiling opening. If the arrival floor of the staircase is a mezzanine and not a spiral staircase opening, you do not need to check this. The number of steps per turn (360 degrees circle) depends on the spiral staircase diameter you need.įirstly check the measures of the ceiling opening (stairwell opening) you have. ![]() Here below you find some useful indications to determine how many steps you need on your spiral staircase plan. Square staircases are in fact a little bit different, we will deal with this in In this article we are explaining how the round spiral staircases work. Height (staircase elevation) but also by the geometry of the circular shape The number of steps is in fact limited by the floor to floor Spiral staircase with glass railing Oak & glass spiral staircase Determine the location of the top landing platform. ![]() Likewise with this spiral staircase design guide you will learn how to design (and build) a perfect spiral staircase step by step. There are indeed some geometrical rules you need to follow and take into account to design a spiral staircase in the correct way and with the right dimensions. Handrail is an extruded PVC coil.In terms of design, there are a number of technical issues you need to take into account when designing a spiral staircase.Double coat with an exterior metal paint. ![]() Product should NOT be painted, To paint would require the following.Product will be shiny metallic when new and oxidize to a soft Grey/white Tread lengths are as follows for the 3 diameters 20 ¼, 24 ½, 28 ½.Staircase kits are available in three different diameters: The height of the spiral stairkit is adjustable between 8′ 3″ to 10′, but with optional accessories, installations from 6′ 10″ to 12′ 4″ are possible. No balcony rail kit is available for the Enduro Steel. Basic household tools are all that are needed for assembly. The handrail is a continuous length of extruded black PVC. The Enduro Steel offers a landing which can fit a square or rectangular opening, or adjoin a header/mezzanine. Hot dipped galvanized for protection against rust and weather.It combines long-term durability with high standards of quality and craftsmanship in design. The Enduro Steel is the spiral staircase for outdoors.
