The market for lifting hardware includes multiple grades, finishes, and standards, so decisions must come from measurable data rather than guesswork. When you need to buy lifting chains, the key is to match chain grade, diameter, and finish with your load, environment, and interface requirements. This guide explains how to read Working Load Limit (WLL) tables, when to choose G80 versus G100, and which finishes perform best in specific industries. By following documented steps, you avoid overbuying, reduce downtime, and ensure every lift passes inspection.

Step 1: Define the Load and Geometry

Start with the heaviest routine load, not one-off peaks. Record the number of legs you will use, the sling angle, and the geometry of the pick points. Use the correct angle factor from EN 818-4 or NACM standards to multiply against the base WLL.

Step 2: Choose the Right Grade

G80 chain: standard in construction, manufacturing, and general rigging; cost-effective and durable.

G100 chain: provides ~25% higher WLL at the same diameter, ideal for space-constrained or high-cycle jobs.

Step 3: Match Diameter to WLL

Use only manufacturer tables. For example, in G80 vertical use:

Values vary by supplier—always confirm with certified data.

Step 4: Select Finish for Environment

Black lacquer: indoor industrial use, basic corrosion resistance.

Hot-dip galvanized: outdoor, freshwater, and general weather exposure.

Stainless steel G80: saltwater, chemical, or food-grade settings; no coatings required.

Step 5: Confirm Components and Standards

All components—master link, hooks, shorteners—must match chain grade. Only purchase chains that meet DIN, ASTM, or NACM standards and carry stamped identification with batch trace codes.

Step 6: Inspect Before First Use

Even new chains require checks: confirm surface condition, measure diameter, and record stamped codes. Keep documentation in a chain register so every sling is traceable from first lift.

Conclusion

When you buy lifting chains, you invest in safety and efficiency, so match grade, diameter, and finish to your exact job—then contact TOPONE CHAIN for certified lifting solutions that meet international standards.
