Jan 01, 1970

In modern construction and industrial applications, vents are an essential part of ensuring air circulation and maintaining indoor air quality. Aier, as an international company exporting to the world, is known for its extensive product line, which includes a variety of plastic and metal valves. For customers, it is crucial to choose the right valve and understand the differences between plastic and metal valves in different scenarios.

Choice of material

One of the most significant differences between plastic and metal valves is their material. Plastic valves are usually made of high-strength plastic materials such as polypropylene or polyvinyl chloride. This makes them lightweight, corrosion-resistant, and relatively inexpensive. In contrast, metal valves are usually made of aluminum, stainless steel or galvanized steel, which have higher strength and durability and are suitable for more demanding environmental conditions.

Suitable for environment and use

Plastic valves are usually suitable for general residential and commercial buildings because their lightweight and economical characteristics make them ideal for most occasions. However, if you want higher durability and excellent fire resistance, metal valves are a better choice for you, when in industrial plants, chemical plants and high-temperature environments. 

Appearance and style

In addition to functionality, valves also affect the appearance and style of buildings to a certain extent. Due to its flexibility, plastic valves usually have more design flexibility to meet the needs of different building designs. The metal valve often presents a solid and professional appearance, which is more suitable for some places with strict requirements and heavy industrialization. Maintenance and cleaning when it comes to maintenance, plastic valves are relatively easy to clean and do not rust easily. Metal valves may require more frequent maintenance, especially in humid environments where they are susceptible to corrosion. However, different environments also have an impact on the durability of different valves, and it is critical to consider the built environment and maintenance costs comprehensively when selecting valves.


To sum up, Aier's product line covers both plastic and metal valves, providing customers with favourable options. When choosing a valve, an informed decision should be made based on the specific use scenario, environmental requirements and aesthetic considerations. Whether it's lightweight plastic valves or sturdy metal valves, Aier is committed to providing high-quality ventilation solutions to customers around the globe.
