How Much Are Granite Stair Treads
Jan 03, 2018


When you want to know the prices of stair treads, you may need to know what is stair? what are treads? How about their functions and processing?

Stairs are used in buildings as vertical traffic between floors. Used for traffic connection between floors and when the height difference is large. Stairs are also to be provided in multi-storey and high-rise buildings with elevators and escalators as the main means of vertical transport. Although the elevators are used as the main vertical transport in high-rise buildings, they still have to be reserved for fire escape. Staircase from the continuous steps of the ladder (also known as ladder run), platform (rest platform) and the envelope components. The distance between the lowest level of the stairs and the highest level of the steps is the length of the ladder, and the total height of the treads is the height of the stairs. China's Warring States Period bronze on the image of heavy housing has been engraved with stairs. From the 15th to the 16th centuries Italy, the interior staircase was freed from the traditional enclosed space, making it an architecturally diverse and decorative part of the building. Tread size should generally be adapted to the size of the

human foot size, but also with the use of different types of buildings related functions. The size of the step includes height and width. Step height and width ratio is the gradient of the stairs. Treads can have different values under the same slope, giving an appropriate range to make people feel comfortable walking. Practice has proved that walking feel comfortable steps are generally smaller and larger width. Therefore, in the choice of aspect ratio, the same slope of the two sizes to a smaller height is appropriate because of walking than the height and width of the step to be more effort. But pay attention to the width can not be too small, not less than 240mm is appropriate, so as to ensure that the focus of the foot focus on the soles of the feet near the center of the heel and make 90% of the effort. For adults, the minimum width of stairstep should be 240mm and the comfortable width should be about 300mm. Step height should not be greater than 170mm, more comfortable height of about 150mm.

The treads of the same staircase, the step height, width size should be the same, the size should not be irregular changes in order to ensure the slope and stride constant relationship. 3. The width of the ladder The width of the ladder is generally decided by the pedestrian flow, in order to ensure the principle of smooth traffic. The width of a single passageway should generally be 800-900mm; the width of a double passageway should generally be 1100mm - 1400mm; the width of a three-way passageway should generally be 1650-2100. If more people are passing, increase the width of 550 + (0-150) mm by per person flow. When the ladder width is greater than 1400mm generally should be set against the wall armrests, and when the staircase more than 4-5 shares of stock flow should generally be added when the middle armrest.

Normally, the shape of stairs are circile or straight, and sizes of treads are 100-150*32-35*3 cm or 100-150*32-35*2 cm, the surface finished are Polished, Flamed, cutting, Honed, Bush Hammered, etc. With Anti-slip grooves or sandblasted lines. Also, Edges processing: Full bullnose, half bullnose, honed, flamed, Flat polished, bevel, laminated straight edge, Laminated bullnose edge, ect., or do as per clients' drawing.

Granite is quite popular to used for stairs, especilaly for outside stairs, because of its hardness. But as we know, there are so many kinds of granite, different colors has their prices. Alos, different shape, different sizes, different surface and processing would make different prices. Welcome to send your details to us to confirm the prices.
