Product Overview
Grade 30 Hot Dipped Galvanized Chain (Long Link). Electronically welded proof coil chain. Finish: hot dipped galvanized – best corrosion protection. Meets or exceeds NACM and ASTM standards. Not for overhead lifting. Never exceed the published working load limit.

Introduction
Grade 30 proof coil chain is manufactured from low carbon steel and designed as a general utility chain for farm use, log chain, tow chain and switch chain applications. Caution: Do not use for overhead lifting. Do not exceed the working load limit.

Parameter

• Grade of Chain: Classified per NACM (National Association of Chain Manufacturers) and ASTM (American Society for Testing and Materials).
• Working Load Limit (WLL): The maximum working load that should be applied in direct tension to an undamaged straight length of chain.
• Proof Test: Minimum tensile force applied during manufacturing as an integrity test; not to be used for design or service criteria.
• Minimum Breaking Force: The minimum force at which the chain broke during manufacture testing; breaking force values are not guarantees for service or design.
• Overhead Lifting: Any lifting that would raise a freely suspended load to a position where a dropped load could cause bodily injury or property damage.
