NACM 2010 G43 High Test Chain Manufacturer & Supplier
NACM 2010 Grade 43 High Test Chain is a high-strength welded carbon steel chain manufactured in accordance with NACM (National Association of Chain Manufacturers) specifications. Grade 43 chain offers significantly higher working load limits than Grade 30 Proof Coil Chain and is widely used in construction, agriculture, transportation, logging, towing, cargo securement, and industrial applications.
Designed for heavy-duty service, G43 High Test Chain provides excellent tensile strength, wear resistance, and durability while maintaining a lighter weight than higher-grade transport chains.
Important: Grade 43 High Test Chain is NOT intended for overhead lifting applications. For lifting operations, Grade 80 or Grade 100 alloy chains should be used.
