1. Cross bracings are major elements in the frame scaffolding system to ensure the stability and rigidity in the longitudinal plan of the scaffolding. Along the both sides of the scaffolding set the crossing braces and lock them with the locking pins on the frame standing tubes to ensure the stability of the whole scaffolding frames. By the way, there is need only to set the crossing braces outside the scaffolding and no need set them inside.

2. There is a building distance to the wall when erecting the crossing braces, which means the distance to the structure margin. The maximum distance is required to be 150mm for the sake of construction safety. If there is a balcony or other surface protruding structures, can set the cantilevered frame inside the frame scaffoldings or take other measures to satisfy this distance of 150mm regulations.

3. The ladder type scaffolding frame remains one of the most common frame scaffolding type which is easy to erect and dismantle. All the elements and accessories are indispensible and shall be provided during the whole construction process.
