G80 chain
G80 Chain
Product Overview
The G80 chain represents the pinnacle of lifting chain technology, engineered for demanding industrial applications where safety, strength, and reliability are non-negotiable. Crafted from high-quality alloy steel, this grade 80 chain undergoes a rigorous quenching and tempering process to achieve exceptional tensile strength and fatigue resistance. Compliant with international standards such as EN 818-2, ASME B30.9, and NACM 2017, the G80 chain is the preferred choice for overhead lifting, rigging, and load securing in sectors like construction, manufacturing, and maritime operations.
Unlike lower-grade chains, the G80 chain offers a superior working load limit (WLL) that is four times its rated capacity before breaking, providing an unmatched safety margin. Each link is precision-welded and individually proof-tested to 2.5 times the WLL, ensuring consistent performance under extreme conditions. Available in a range of diameters from 6mm to 26mm, our G80 chain is color-coded blue for easy identification, distinguishing it from other grades and preventing mix-ups on job sites. Whether you're hoisting heavy machinery, securing cargo, or rigging complex lifts, the G80 chain delivers unwavering dependability.
Our G80 chain is designed not just for strength but for longevity. Its corrosion-resistant surface treatment and optimized metallurgy resist wear from abrasion, impact, and environmental exposure, extending service life and reducing replacement costs. As a B2B supplier specializing in international trade, we ensure every meter of G80 chain meets or exceeds global quality benchmarks, backed by comprehensive testing and certification documentation.

Application Scenarios
The versatility of the G80 chain makes it indispensable across diverse industries. In construction, it's the go-to solution for crane lifts, concrete bucket hoisting, and formwork rigging, where its high WLL handles loads up to 21 tonnes safely. Mining operations rely on G80 chain for transporting ore skips, drilling equipment, and underground conveyors, thanks to its abrasion resistance in dusty, rocky environments.
Maritime and shipping sectors use G80 chain in shipbuilding, cargo securing, and offshore platform rigging, with its corrosion protection standing up to saltwater exposure. Manufacturing plants employ it for overhead conveyors, assembly line hoists, and heavy machinery relocation. In logistics and warehousing, G80 chain excels in pallet slings and forklift attachments, optimizing material handling efficiency.
Additionally, the G80 chain is ideal for entertainment rigging in theaters and events, pulling winches in towing applications, and rescue operations requiring reliable strength. Its compliance with OSHA, EU Machinery Directive, and other regulations ensures seamless integration into global supply chains.
Advantages
Opting for our G80 chain yields tangible benefits over competitors. First, its grade 80 designation delivers 25% higher strength than G70 chains, allowing lighter assemblies for the same load capacity, which reduces shipping weights and crane fuel consumption. The chain's fatigue life exceeds 200,000 cycles under standard testing, minimizing downtime and maintenance expenses.
Safety is paramount: With a 4:1 safety factor and mandatory proof testing, the G80 chain prevents catastrophic failures common in substandard products. Its uniform link design ensures even stress distribution, reducing wear points. Environmentally, the durable construction lowers waste, as chains last longer in service.
Cost-efficiency is another edge—initial investment pays off through fewer replacements and enhanced productivity. We provide full traceability with batch numbers, heat codes, and third-party inspections from bodies like Lloyd's Register or DNV, building trust in every link.

FAQ
What is the difference between G80 chain and G100 chain?
The G80 chain has a tensile strength of 800-1000 N/mm² with a 4:1 safety factor, suitable for most lifting tasks. G100 offers higher strength (1000 N/mm²) and a 4:1 factor but is specialized for ultra-heavy lifts; G80 remains more versatile and cost-effective.
Is G80 chain suitable for overhead lifting?
Yes, G80 chain is specifically designed and certified for overhead lifting when used in proper sling configurations with compatible end fittings. Always adhere to WLL and inspection protocols per EN 818-2.
How do I maintain my G80 chain?
Store in a dry, ventilated area away from chemicals. Inspect before each use for wear, cracks, or elongation (max 5% allowed). Clean with mild soap, lubricate links periodically, and retire if damaged. Follow manufacturer guidelines for proof load re-testing.
What standards does your G80 chain comply with?
Our G80 chain meets EN 818-2, ASTM A973/A973M, and Federal Specification RR-C-271. Full certifications, including test certificates, are supplied with each order.
Can G80 chain be used in corrosive environments?
Standard G80 chain features a black oxide coating for moderate protection. For harsh conditions, opt for our galvanized or electropolished variants, which extend service life significantly.
What is the minimum order quantity for G80 chain?
We accommodate small orders with cut lengths starting at 1 meter, up to full 100m drums. Bulk pricing applies for larger volumes to optimize your procurement.
