Ladder board specification:

Staircase staircase at all levels of the
leading edge of the line known as the slope line. The angle between the slope
line and the horizontal plane is the slope of the staircase. Stairs slope is
generally 20 degrees -45 degrees is appropriate, about 30o more common. Special
function of the stairs required different slope, for example, the slope of the
ladder in more than 60 degrees, the special stairs generally take 45 degrees
-60 degrees, indoor and outdoor step of the slope of 14 degrees -27 degrees,
slope gradient is usually 15 degrees the following. Home for the elderly and
children, the proposed gradient of the stairs not too much.

Ladder board size specification:

The size of the step should generally be
adapted to the size of the human foot step, the size of the step, including
height and width. For adults, the minimum width of the stair step should be
240mm, the comfortable width should be about 300mm. Stepping height should not
be greater than 170mm, more comfortable height of 150mm or so. There are
elderly children at home, for the convenience of their use, the proposed height
range in the range of 150mm ~ 230mm.

According to the installation method, there
are generally two types of welding fixing and bolt fixing, which are directly
welded on the keel, and do not need to be added with the side plate of the step
board, so it is relatively economical and durable. The steel plate is used as a
staircase. However, it is not easy to disassemble the bolts, and the sides of
the stepped boards need to be thickened on the side plates. Stepping board
installation is fixed directly by the bolt can be repeated recycling.
