The smoke vent skylights are installed in different regions, and the technical parameters and window types that need to be considered are also different. For areas with large snow in the north, the local snow load should be fully considered when choose the window type.

1. What is snow load

Snow load refers to the calculated snow pressure on the roof of a building. The size of the snow load value mainly depends on the amount of snowfall in each area based on meteorological data, the form of the roof, the geometric size of the building, and the normal use of the building. Snow load is one of the important parameters that affect the structural safety of factory smoke vent skylights.

2. The snow load needs to be reasonably valued

Most areas of my country are in the temperate zone, and the snowfall period in general areas is less than 4 months. Mainly in the Northeast, Inner Mongolia, Xinjiang, Qinghai and other regions, the winter will last a long time and snow is thick. Due to the low temperature, the snow may not melt throughout the winter after the snow is covered. The old snow is covered with new snow, which increases the snow pressure and determines the snow load. Users should choose smoke ventilator based on the actual meteorological conditions in each area.

3. The influence of steel structure materials on the value of snow load

When install daylighting natural ventilator in northern areas with heavy snowfall, the first factor that needs to be considered is the wind and snow load capacity of the smoke ventilation. The snow load capacity of the roof vents of industrial plants mainly depends on the design form, material and thickness of the rain shield of the steel structure, among which the type and specification of the steel structure material are very important.
