The key features of this aquaculture escape-proof mesh focus on seawater resistance and escape prevention. First, it uses Type 316L marine-grade stainless steel, which contains molybdenum, providing superior resistance to chloride-induced corrosion compared to standard 304 stainless steel, passing a 10,000-hour salt spray test without significant rust or degradation. The reverse twill weave structure creates a tight, rigid mesh with 1.8mm nominal apertures, which is small enough to prevent juvenile and adult fish from escaping while allowing water, plankton, and nutrients to flow through, ensuring optimal water quality and fish health. The 0.8mm wire diameter delivers high tensile strength of ≥600MPa, allowing it to withstand strong ocean currents and wave impact without tearing or deforming, even in rough sea conditions. Optional anti-biofouling silicone coating creates a smooth, non-stick surface that prevents algae and barnacle buildup, reducing the need for frequent cleaning and extending service life by up to 20%. Additionally, it is lightweight and flexible, making it easy to install and handle, and it can be cut and customized to fit any fish cage size or shape, providing a versatile solution for marine aquaculture operations.
This marine aquaculture escape-proof mesh has technical specifications tailored for saltwater environments. The base material is Type 316L marine-grade stainless steel, which meets ASTM A312 standards and contains 2.0-3.0% molybdenum, providing exceptional seawater corrosion resistance. The wire diameter is 0.8mm, which is optimized for balancing strength and flexibility, ensuring it can withstand strong ocean currents while being easy to handle. The mesh count is 12 mesh, with a nominal aperture of 1.8mm, which is ideal for preventing fish escape while maintaining water flow. The standard roll width is 1.5 meters, with customizable lengths ranging from 10 to 40 meters to fit different fish cage sizes. The seawater corrosion resistance is tested to ≥10,000 hours in a salt spray test, ensuring it does not rust or degrade in saltwater environments for at least 5 years. The tensile strength is ≥600MPa, meaning it can withstand a pulling force of 600MPa per square millimeter without breaking. The weaving type is reverse twill weave, which creates a tighter, more rigid mesh structure than plain weave, reducing the risk of fish escape. Optional anti-biofouling silicone coating is 0.2mm thick, non-toxic, and eco-friendly, preventing algae and barnacle buildup without harming aquatic life. The applicable water depth is 0-50m, making it suitable for both coastal and offshore fish farming operations.
This marine aquaculture escape-proof mesh is primarily used in offshore and coastal fish farming operations, including salmon, tuna, and sea bass farming. It is installed as a barrier around fish cages, preventing fish from escaping while allowing water, plankton, and nutrients to flow through, ensuring a healthy aquatic environment. It can also be used in shrimp farming to create escape-proof ponds and in shellfish farming to protect young shellfish from predators. Its seawater corrosion resistance makes it suitable for long-term use in saltwater environments, where traditional nylon or polyethylene meshes would degrade quickly due to UV exposure and saltwater corrosion. Optional anti-biofouling coating reduces algae and barnacle buildup, which can clog the mesh and reduce water flow, improving fish health and reducing maintenance time. Its high tensile strength and rigid structure ensure it can withstand strong ocean currents and wave impact, even in rough sea conditions, providing a reliable, long-lasting solution for marine aquaculture businesses. It can be customized in length and width to fit any fish cage size or shape, including circular, square, or rectangular cages, making it a versatile choice for small-scale and large-scale aquaculture operations.
