Product overview
Grade 30 proof coil chain supplied on a full drum. Electronically welded proof coil construction manufactured from low carbon steel. Finish listed as electro-galvanized (product title); some documentation may reference hot-dipped galvanized — verify finish with the supplier. Meets or exceeds NACM and ASTM classifications. Not for overhead lifting; never exceed the published Working Load Limit (WLL).

Introduction
Grade 30 Proof Coil Chain is a general-purpose utility chain used for farm work, log chain, towing and switch chain applications where overhead lifting is not intended.

Caution

• Do not use for overhead lifting.
• Never exceed the published Working Load Limit (WLL).

Parameter

• Grade of Chain: NACM (National Association of Chain Manufacturers) and ASTM classify chain grades; a higher grade provides a higher WLL for the same nominal size.
• Working Load Limit (WLL): The maximum recommended working load applied in direct tension to an undamaged straight length of chain.
• Proof Test: Minimum tensile force applied during manufacturing to verify integrity; this is a manufacturing test and not a design criterion.
• Minimum Breaking Force: The force at which a tested sample failed under increasing direct tension; a manufacturer acceptance test and not a service guarantee.
• Overhead Lifting: Lifting that would place a freely suspended load where dropping it could cause injury or damage; this chain is not rated for such use.

• Standard: Meets or exceeds NACM / ASTM classifications.
• MOQ: 100 meters.
