Fishing chains are corrosion-resistant chain systems designed specifically for aquaculture, fishing operations, and marine engineering. They are used to fix fishing nets, anchor aquaculture cages, connect fishing equipment, and bear loads in seawater and freshwater high-humidity environments. They must have three core properties: resistance to salt spray corrosion, high breaking load, and wear resistance.
Fishing chains have three specifications: short link chian, middle link chain and long link chain. Different types of fishing chains have different features.
Short Link Fishing Chain:
Short link fishing chain has a good yield performance that can meet a variety of applications. The short link chains are the heaviest among the fishing chain series. Its chain diameters range from 7mm, 10mm, 13mm, 16mm, 19mm to 20mm.
Mid Link Fishing Chain:
The strength of mid link chain is the same as short link chain, but due to its smaller number of links per meter, the wear of inner link is less. The mid link chains is lighter than short link chains and also cheaper. Mid link fishing chain diameter ranges from 10mm, 13mm, 14mm, 16mm, 19mm, 22mm to 26mm.
Long Link Fishing Chain:
Long link chains are much lighter than short link and mid link chains. The rotation space of its inner links is larger and convenient for the installation of accessories. Long link chain diameter ranges from 7mm, 9mm, 11mm, 13mm, 16mm, 19mm, 22mm to 28mm.
