Choosing high-quality plastic netting is not only about durability. The right product also depends on mesh size, structural design, and its ability to meet specific application requirements.
Why can the same type of plastic netting be suitable for aquaculture in one case, while another version is more suitable for agricultural or industrial applications? Selecting the wrong specifications can reduce performance, increase replacement costs, and affect the safety and efficiency of the entire system.
In this guide, SIAM Brothers Vietnam will help you understand the most common plastic netting sizes, how to select the right mesh size for different applications, and the key factors to consider when choosing high-quality netting products.
Small mesh plastic netting features narrow openings between each mesh, helping prevent small fish, young aquatic species, or small objects from passing through. This type of netting is widely used in aquaculture applications and several agricultural solutions.

For example, in river or offshore fish cage systems:
- If the mesh size is too small, water flow may be restricted, reducing oxygen exchange and increasing the risk of algae buildup.
- If the mesh size is too large, smaller fish may escape.
Therefore, choosing the right plastic netting mesh size should be based on:
- The size of the aquatic species.
- Growth stage requirements.
- Actual environmental conditions at the installation site.
Large mesh plastic netting is commonly used in applications that require:
- High durability.
- Better water drainage.
- Large-area coverage.
This type of netting is often suitable for outdoor environments where the product is exposed to frequent impacts from:
