Product Introduction
Semi-rigid Polymer Composite Network (HaideliNet) adopts special netting technology with our own intellectual property rights to produce high-durability, anti-corrosion, high pollution- resistance, super deep sea aquaculture network.
After years of intensive research and development, HaideliNet is completely superior to copper alloy mesh and composite nylon/ polyethylene mesh which are used in aquaculture industry. Its durability, pollution pollution-resistance, light- weight, with the deformation- resistance mesh, mesh deformation resistance and many other characteristics have significantly improved the production efficiency in aquaculture production. It has become the most advantageous net in deep-sea aquaculture industry.
In addition to produce HaideliNet, according to customer needs and mesh characteristics, also provide customers with the design, manufacture and installation services of netting system for deep- sea aquaculture platform, cage and purse net as well as the matching maintenance services such as net washing, net changing and net repairing, to meet the needs of different types of customers.
HaideliNet is the best choice for your aquaculture nets. HaideliNet provide new materials and equipment for aquaculture. Investors will benefits from the application of HaideliNet. HaideliNet can reduce production intensity and risk, significantly improve production efficiency and benefit from it benefit. If you compare the cost of the entire lifecycle of HaideliNet with the traditional cage nets while using cages, platforms, boats or seines, you will find many advantages of our nets, like the increasing of fisheries production, operating costs reducing.
Long-Lasting Design Life
HedeliNet is made from PET (Polyethylene Terephthalate) monofilaments woven together to form a tough, high tensile strength, structurally stable hexagonal mesh. HedeliNet has been exposed to mechanical damage and extreme weather. Useable in wide temperature range. HedeliNet offers a 10- 20year design life.

Molecular bonding of polymer composite monofilaments is still. unstable at the end of production, and will be stabilized after 2 to 3years, the strength will also be improved constantly during the meantime. According to the test results，the strength will not decrease sharply with time, and the durability of applications on land can be maintained for more than 50 years. Applied to the field of marine aquaculture, the longest life span can be more than 10 years.
