Brief
Windlass Grade 30 Full Drum Chain Domestic Proof Coil ISO. Electronically welded proof coil chain with hot-dipped galvanized finish for enhanced corrosion protection. Meets or exceeds NACM and ASTM requirements. Not intended for overhead lifting. Never exceed the published Working Load Limit (WLL).

Introduction
Grade 30 proof coil chain is manufactured from low carbon steel and serves as a general-purpose chain for applications including windlass and deck use, towing and general utility tasks. The electronic welding process ensures consistent link integrity.

Caution

• Do not use for overhead lifting.
• Do not exceed the published Working Load Limit (WLL).

Parameter

• Grade of Chain: Classified per NACM and ASTM; higher grade indicates higher WLL for the same size.
• Working Load Limit (WLL): Maximum recommended working load in direct tension for an undamaged straight length of chain.
• Proof Test: Manufacturing test force applied under increasing direct tension to verify production integrity; not to be used for design or service criteria.
• Minimum Breaking Force: The minimum tensile force at which chain samples broke during manufacture; this is a manufacturer acceptance test and not a service guarantee.
• Overhead Lifting: Refers to lifting that could position a suspended load where dropping it would risk injury or damage; this chain is not rated for such use.
