Product Overview
Direct factory manufacturer of premium Grade 100 (G100) alloy lifting chains engineered for overhead crane operations, heavy-duty chain slings, mining equipment, and offshore rigging. Engineered from micro-alloyed 23MnNiCrMo5 steel, our G100 chains deliver 25% higher working load capacity than standard Grade 80 chains of the same link diameter, drastically reducing total assembly weight and operator fatigue.
Fully heat-treated, 100% proof-load tested, and supplied with EN 10204 3.1 Inspection Certificates.
Key Advantages
25% Higher Loading Efficiency: Lift heavier payloads without increasing chain size. A 10mm G100 chain achieves a 4.0-Ton WLL, matching or exceeding the performance of a heavier 13mm G80 chain.
Reduced Assembly Weight: Lighter chain slings allow easier manual handling, lower freight costs, and reduced physical fatigue for rigging technicians.
Micro-Alloyed Steel Construction (23MnNiCrMo5): Advanced alloy formulation with balanced Nickel, Chromium, and Molybdenum ensures high impact resistance and structural integrity under dynamic shock loading.
100% Continuous Proof Testing: Every meter of chain undergoes proof loading at 2.5 times its Working Load Limit (WLL) on automated vertical tensile testing beds before final surface coating.
Permanent Embossed Identification: Stamped with "G10" or "G100" plus traceable mill batch codes every meter for immediate job-site safety verification.
