This is because the spaces with the turn also require less length to cover the same distance for ascending and descending. It is also a <strong>very versatile <\/strong>staircase from practical and aesthetic points of view.<\/p>\n\n\n\n<p>The main <strong>disadvantage<\/strong> is the difficulty in calculating its structure. Like any other staircase, winders must respect the parameters set forth in the Technical Building Code (TBC). By using these, it is possible for the staircase to be <strong>limited in size<\/strong> (i.e., it will be used by a limited number of people and will be located in a predominantly private space) or in the <strong>public sphere<\/strong>. In any case, for the staircase to be considered <strong>safe<\/strong>, it must comply with a number of <strong>technical measures <\/strong>related to the slope, angles, heights, steps, etc.<\/p>\n\n\n\n<p>Other <strong>possible disadvantages <\/strong>are similar to those of the spiral staircase:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>If the narrowest side of the angled steps is too small to allow traffic, the staircase <strong>will only work in one direction<\/strong> because it won&#8217;t be possible for two people going in opposite directions to use it at the same time.

In the case of the <strong>winder staircase shown<\/strong>, the shapes of the steps can be altered, as can the materials of the supporting structure and railings to make <strong>creative compositions<\/strong>. On the other hand, the <strong>lined winder staircase<\/strong>, thanks to the combination of straight and curved shapes and the twisting of its lower coating, offers <strong>fluid, dynamic shapes <\/strong>that have great visual appeal and that can be combined in different ways in both <strong>minimalist <\/strong>and more classic environments.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What are the main safety standards that a winder staircase must meet?<\/strong><\/h2>\n\n\n\n<p>As with all safety regulations, these standards <strong>vary by country<\/strong>, time, and the <strong>nature of each project <\/strong>(public, private, mass use, etc.).
