The construction of industrial product-conveying ducts for abrasive materials requires the use of sheet metal because it offers the necessary durability and strength to withstand the wear and tear from abrasive substances. Sheet metal is resistant to impact and can maintain its integrity under harsh conditions, making it an ideal choice for handling materials that can cause erosion or damage to less robust materials.

Additionally, sheet metal can be shaped and sealed effectively to create the necessary ducting configurations, ensuring efficient airflow and minimizing leaks. This is crucial in maintaining performance standards within an industrial setting. While other materials like polyvinyl chloride and fiberglass may be suitable for certain applications, they do not provide the same level of durability needed when dealing with abrasive materials. Therefore, the use of sheet metal is the most practical and effective choice in this scenario.
