Stairs come in a variety of styles and designs meant to serve different purposes. The designs of stairs that are installed in a site depend on the amount of space available. One of the most popular stair designs is floating stairs. People usually describe this stair design as the most stunning or intriguing because the stairs look as though they do not have any risers to hold any weight. The risers vertically support the treads, which are the horizontal planks you walk on. Even though it does not appear to have the ability to support much weight, the floating design can hold up to 440 pounds. To achieve this, the engineers carefully design steel reinforcements to harness the inertia that using the stairs can generate. The designer hides these reinforcements from view.
