carbon steelhot-dip galvanised steelcorrosion-resistant

Overview
Grade 30 hot‑dipped galvanized proof coil chain supplied on full drum. Electronically welded proof coil construction. Finish: hot‑dip galvanized for corrosion resistance. Meets or exceeds NACM and ASTM Grade 30 classifications. Not for overhead lifting. Never exceed the published Working Load Limit (WLL).

Introduction
Grade 30 proof coil chain is manufactured from low carbon steel and provides a general utility chain suitable for agricultural, logging, towing and switch chain applications where a proof coil chain is specified.

Caution

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

Parameter

• Grade of Chain: NACM and ASTM classify chains by grade; Grade 30 indicates the specified strength class for this product.
• Working Load Limit (WLL): Rated capacity – maximum recommended working load in direct tension for an undamaged straight length of chain.
• Proof Test: Manufacturing test force applied to verify integrity; proof test values are manufacturing verification and are not to be used as design criteria.
• Minimum Breaking Force: Minimum tensile force measured during manufacture at which the chain breaks; breaking force values are manufacturer acceptance tests and not for design use.
• Overhead Lifting: Not permitted — lifting that could place personnel or property at risk if the load were to fall.
