With what material are damaged ventilators usually replaced?

Damaged ventilators are commonly replaced with plastic materials due to their lightweight nature, resistance to corrosion, and adaptability to different environmental conditions. Plastic ventilators are also more cost-effective, making them a preferred choice for container repairs. They can be produced in various shapes and sizes to fit different containers efficiently, ensuring a proper seal and functionality. This material also allows for adequate ventilation while minimizing the risk of damage from external factors, which is particularly important in a maritime environment where containers are often exposed to harsh conditions.

In contrast, materials such as wood, steel, and glass may not be as practical for this purpose. Wood may not withstand the marine environment due to susceptibility to moisture and decay. Steel, while durable, can add unnecessary weight and might suffer from rust and corrosion. Glass, while aesthetically pleasing, is fragile and poses a greater risk of breakage during handling or in transit. Thus, the preference for plastic ventilators is rooted in their durability, functionality, and overall suitability for container use.
