The size of stair step board should be suitable for the adult footwork and depth, different in the use of the environment, and its use function is related. The scale of the step plate contains height and depth. The ratio of the height to the depth is the slope of the staircase. The step plate is in the same viewpoint the device of the device is in step height falling or the depth of the addition, and extending the length of the stairs, and vice versa can be reduced.

The length of the stairs. In order to have a comfortable feel for climbing the stairs, we can control the numerical value of order to a reasonable range. Practice has proved that feel refreshed step is appropriate to add the height of the step down the steps of depth, therefore in depicting stair steps to reduce the slope of stair, smaller for the same step of the slope in a highly advisable, because walking than height.

It's easier to make strides than deep ones. Depth but not too small, too small can't ensure that everyone's focus on the feet, and should not be less than 245 mm is appropriate, the depth of 245 mm can ensure the foot point of focus on arch nearby, also can make the heel focus has most step on step plate. So the minimum depth of scaffolding plank should be 245 mm, comfortable depth. It should be about 300 millimeters. The height of the steps is not less than 155mm, not more than 200 mm.

In each staircase of the same staircase, the consistency of the height and depth of the step should be adhered to, so that it can ensure that the stairs are in the same step as the stairs, and that it will not give people an unaccustomed feeling. The ladder usually has to think about the number of traffic people to design the width, to make sure the traffic flow is smooth. The width of a one-way staircase is usually described as 600 mm and above, and the width of the two - way passes should be described as more than 1200 mm and above, the stairs should be increased to more than 2400 mm, with maximum limit to ensure that people are not congested.

When the stairway is wider than 1 to 2 meters, you should think about adding armrests to one end of the wall. The mingheng stair step board can be installed in all kinds of incline stairs, the various height and the width standard and the supporting application.
