Smoke vent is commonly used in modern industries. It is mainly composed of frame, a peripheral guard plate, a flooding plate, a drainage ditch, a rain shield, an electric switch mechanism, etc., which play the functions of fire-fighting smoke exhaust, ventilation, and lighting in the actual production of modern industrial plants. When choose a steel structure roof vents, fully consider the actual situation of the project, and the design should meet the needs of the project.

1. Meet the need of local wind and snow load

Smoke vent is a kind of ventilation equipment installed on the roof, exposed to the outside, withstands wind and rain. Therefore, for areas with strong winds and heavy snow, the local wind and snow loads should be fully considered when install roof-type natural ventilator. The load parameters are scientifically calculated to ensure the safety performance of the factory building after the smoke vent skylight is installed.

2. Meet client's seismic level

Generally, the seismic resistance level of daylighting natural ventilator prescribed by the state is level 7, and the smoke vents supplier must meet or exceed the national standard when design roof smoke vent. For some owners, there are special requirements on the seismic level, and the roof ventilator manufacturer needs to meet the owner’s seismic level requirements.
