The price of ridge ventilator is determined by structural safety, waterproofing, anti-corrosion, production equipment, processing technology, ventilation performance, raw materials, construction plans, and finished products production. Mcwell will introduce the importance of structural safety of the natural vent.

Some small smoke vent manufacturers do not have specialized structural engineers to perform calculations, and choose the size of roof smoke vent profiles based on their feelings. Although the cost is low, they have not been calculated by structural mechanics. There are serious safety hazards that are usually invisible at all. Encountered with severe weather conditions, safety accidents such as collapse and collapse may occur, causing major personnel and property losses. Such incidents have occurred in the smoke vent skylights industry.

Regarding structural safety, the skeleton of Mcwell's ridge ventilator strictly complies with the requirements of the national building load code. The structural designer uses the PKPM structural design software to check the ventilation skylight frame, and then takes the value according to the weather conditions and regulations across the country to make the ventilation skylight meet the requirements of local wind load, snow load and seismic grade, and ensure the safety and reliability of the structure of the ventilation skylight. For example, for a ventilation skylight with a 3 meter throat, McWay generally uses 80*60*3.0 or 80*60*2.5 as the main frame of the roof ventilation skylight after calculation by PKPM software.
