Anchor Chain

: http://gyfasteners.com/3-2-anchor-bolt.html

Our anchor chains connect the anchor and the ship hull, and are used for transmitting and buffering external forces applied to the boat. Not all anchor chains are the same, and they come in a variety of types and grades that can be extremely important for users to know the difference between, in order to use them properly. The most popular varieties are those made from galvanized steel in different high test strengths and grades. WAC's chains are coated with an abrasion resistant and anti-corrosive paint to prevent abrasion and corrosion to the marine chain caused be seawater.

Specifications and Parameters of Anchor Chain
Product: U2/U3 marine anchor chain
Type: Stud link chain
Diameter: 12.5mm-132mm
Material: 20Mn2, 30Mn
Surface finishing: Black paint coating; hot galvanizing if customer requires; The breaking test load of our anchor chain complies with relevant standards (See details in the following table).

We can produce U2 and U3 grade hot galvanized anchor chains to multiple specifications and standards, including BV, NK, GL, KR, DNV, LR, ABS, CCS and RINA. Customers can select the proper model of stud link chain based on their specific application needs, including cargo ships, bulk cargo ships, oil tankers, trailing suction for hopper dredgers, ferries and other large ships. In addition, we can also manufacture custom welded anchor chains according to drawings or samples provided by our customers.
