High Tensile Black Heavy Duty Welded Alloy Steel G80 G100 Lifting Link Load Chain

Core Features

1. High-Strength Alloy Steel ConstructionCrafted from high-quality alloy steel, the chain exhibits superior tensile strength and impact resistance, minimizing the risk of deformation or breakage under heavy loads. The precision-welded links ensure uniform force distribution, enhancing overall structural integrity and extending service life.
2. Dual G80/G100 Strength Grades
   • G80 Grade: Offers a minimum tensile strength of 800 N/mm², suitable for most industrial lifting tasks (e.g., machinery moving, warehouse loading) with a safe working load (SWL) range tailored to standard operational needs.
   • G100 Grade: Boasts an even higher tensile strength (1000 N/mm²) for ultra-heavy-duty applications, such as port container handling, construction steel lifting, or mining equipment relocation—providing an extra margin of safety for extreme loads.
3. Black Heavy-Duty Surface TreatmentThe chain features a specialized black coating (e.g., black oxide, powder coating, or galvanized-black finish) that provides robust protection against corrosion, rust, and abrasion. This treatment ensures optimal performance in outdoor, humid, or dusty environments (e.g., construction sites, marine terminals) while maintaining a sleek, industrial aesthetic.
4. Heavy-Duty Link DesignEach link is engineered with a thickened cross-section and smooth edges to reduce stress concentration and prevent damage to lifted materials (e.g., finished steel, delicate machinery). The compatible link size allows easy connection to common lifting accessories (e.g., hooks, shackles, hoists) for versatile use.
5. Compliance with International Safety StandardsManufactured in accordance with global lifting regulations (e.g., ISO 3077 for G80 chains, ISO 18340 for G100 chains, EN 1677 for European markets), the chain undergoes strict quality control tests (including load testing, fatigue testing, and dimensional inspection) to ensure compliance with safety requirements. Each unit is marked with grade, SWL, and manufacturer information for traceability.
