steelgalvanizedhot-dip galvanised steel

Product Overview

• Electrically welded binder chain
• Finish: self color (hot-dipped galvanized)
• Meets or exceeds NACM and ASTM standards (A391 & A413)
• High strength-to-weight ratio
• NOT to be used for overhead lifting
• NEVER exceed published working load limit (WLL)
• Proof tested and certified

Introduction
Grade 43 chain offers higher tensile strength than Proof Coil (Grade 30). Commonly used as binder, high-test tow or log chain, Grade 43 typically provides approximately 50% higher working load limit compared with Proof Coil of the same size. These chains are supplied with a clevis grab hook on each end. Grade 43 is NOT approved for overhead lifting and must be used only within published WLL.

Parameter

• Grade of Chain: NACM (National Association of Chain Manufacturers) & ASTM classify chains by grade; higher grade indicates higher WLL for same chain size.
• Working Load Limit (WLL): Maximum safe working load in direct tension on an undamaged straight length of chain.
• Proof Test: Minimum tensile force applied during manufacture under increasing direct tension to verify integrity; not a design criterion for service loads.
• Minimum Breaking Force: Acceptance test measurement of breaking load during manufacture; not a guarantee for service conditions.
• Overhead Lifting: Any lifting that suspends a load in a position where dropping it could cause injury or damage. Grade 43 is not approved for overhead lifting.
