Use of square tube, round bar (or Plum), and angle steel and other pultruded profiles can be combined into a ladder. Fiberglass ladder can be used both indoors can also be used outdoors. In addition to being free to move independent products, glass and steel ladders are often part of the system as the platform was fixed installation, and can be attached to cage. Immersed in the chemical plant and the need to place a liquid substance (such as swimming pools), glass and steel is the preferred material of the ladder program. 

 Ladder for the platform are two designs, one is a ground support, the next four ladder diagram fall into this category; the other is completely dependent on the wall (without ground support). Mainly in the bottom of the two designs are different on the support, the other is basically the same, all reference to the OSHA 1910.27 standards.
