The material selection of Rectangular Fire Dampers is extremely critical to their fireproof performance and service life. The following are the main points for material selection.
The first is the place of use. The fire protection requirements and environmental conditions of each place are different. For example, in areas where corrosion is possible, stainless steel or corrosion-resistant materials must be selected to maintain the durability and stability of the fire damper.
The fire rating should not be ignored. The fire rating of the Rectangular Fire Damper is related to its fire control effect. High-grade fire dampers need to be matched with high-performance materials. When selecting materials, the fire resistance time and fireproof characteristics must be considered to make them meet the requirements of building fire protection.
Cost-effectiveness is also important. On the basis of ensuring fire protection performance, we must look for cost-effective materials. The prices of fire dampers of different materials are different. It is not that the higher the price, the better the performance. It needs to be determined by comprehensive material performance, price and service life.
In terms of specific materials, carbon materials are resistant to high temperatures and have good stability, and are suitable for high temperature environments; galvanized sheets are high in strength and corrosion-resistant, and are often used in general environments. The valve plate thickness is at least 1.5 mm galvanized steel sheet, and the valve body is made of non-combustible materials such as gray cast iron.
In addition, when selecting a Rectangular Fire Damper, in addition to the material, its structure, function and scope of application should also be taken into consideration. For example, the automatic closing and manual adjustment functions must be available and can meet the needs of specific environments. The blades, shell thickness and easily fusible parts must also comply with relevant standards and specifications. In short, the selection of rectangular fire damper materials should be based on a variety of factors to play a key role in fire and protect the safety of buildings and personnel.
