Selecting the right lifting chain requires comparing performance, standards, and real-world cost. A G80 alloy chain remains the industry workhorse because it balances strength, durability, and affordability, but buyers often ask how it stacks up against other grades and materials. This article uses published Working Load Limit (WLL) data and application standards to compare G80 alloy chain with G100 alloy, stainless G80, and galvanized lifting chains. The aim is to show measurable differences so operators and buyers make decisions backed by traceable data, not assumptions.

G80 Alloy Chain: The Industry Benchmark

A G80 alloy chain is manufactured from quenched and tempered alloy steel, offering high tensile strength and excellent fatigue resistance. It meets EN 818-2 and NACM standards, which means every chain is proof tested and stamped with traceable codes. It provides the foundation for general lifting, construction, and manufacturing work.

Comparison with G100 Alloy Chain

The main difference is strength-to-size ratio:

Key takeaway: G100 allows downsizing, which saves weight and hook space, but costs more.

Comparison with Stainless Steel G80

Strength: Alloy G80 typically exceeds stainless G80 in WLL.

Corrosion resistance: Stainless chains handle saltwater and chemical exposure better.

Applications: Food processing, marine, and chemical industries favor stainless despite higher cost and lower WLL.

Comparison with Galvanized Chains

Hot-dip galvanized chains resist rust outdoors but may increase pitch and thickness, affecting fit.

Electro-galvanized options suit indoor humid conditions but offer shorter corrosion cycles.

G80 alloy chains, when black lacquered, remain the standard for construction but need more maintenance in marine use.

Which Chain Fits Which Application

Use G80 alloy chain: general construction, rental fleets, manufacturing shops.

Use G100 alloy chain: space-limited, high-frequency lifts where lighter gear matters.

Use stainless G80: salt mines, marine docks, and food-grade facilities.

Use galvanized chains: outdoor storage yards, bridge construction, and port equipment.

Conclusion

A G80 alloy chain offers proven strength and compliance across industries, yet knowing how it compares to G100, stainless, and galvanized options ensures you always match chain to environment and load—then contact TOPONE CHAIN for certified alloy lifting chains suited to your projects.
