Ordinary Galvanized Chain VS High-Tensile Chain

To help you understand more intuitively, I have organized their core differences into a table:

Comparison Dimension     rdinary Galvanized Chain (General Purpose)            G80 High-Tensile Chain (Lifting Specialized)
Main Material Ordinary      low-carbon steel High-quality                                alloy steel (e.g., 20Mn2, 25MnV)
Core Process                   Electro-galvanized or hot-dip galvanized after welding Alloy steel heat treatment + optional surface galvanizing
Corrosion Resistance      Good, suitable for outdoor, humid environments       Can be galvanized, but main advantage is strength
Load Capacity               Low, strictly prohibited for lifting High,                     with clear load standards (4:1 safety factor)
Main Uses                  Guardrails, lashing, hanging, decoration, general pulling  Professional hoisting, equipment towing

🛡️ Why Choose "Galvanized"?

Choosing an ordinary galvanized chain mainly values the rust resistance provided by its surface treatment. The galvanized layer acts like a "rust-proof coat" for the chain:

· Electro-galvanized: Appearance is silvery-white or bluish-white. The coating is relatively thin, suitable for general indoor or mildly humid environments.
· Hot-dip galvanized: Stronger anti-corrosion ability, with a thicker and more durable zinc layer. Suitable for harsh environments with long-term outdoor exposure.

💡 How to Distinguish and Choose?

When purchasing or using, it is recommended to keep these points in mind:

1. Clear Purpose is Key: The primary principle is safety. If it is used for lifting heavy objects, you must choose G80 or higher grade lifting chains. If it is for guardrails or tying down goods, then ordinary galvanized chain is a cost-effective choice.
2. Pay Attention to Standards: Ordinary chains usually do not have clear load standards, whereas G80 chains will explicitly state compliance with standards like EN818-2 or JB/T8108.

3. Observe Appearance Details: A good galvanized layer should be uniform and free of rust spots. Choose electro-galvanized (bright white) or hot-dip galvanized (matte, thick) based on the environment.
