Self-Color vs Galvanized Chain: Bare Steel or Zinc Coated?
One is the chain as manufactured, with no coating at all; the other carries a zinc layer for corrosion protection. Choose bare steel when it is enough, and galvanized when it is not.
Two chains can be identical in size and grade yet finished very differently. A self-color chain is the steel as manufactured, with no coating; a galvanized chain carries a zinc layer over the same steel. The choice is not about strength: it is about where the chain will live, and whether a bright or natural finish is wanted.
What Self-Color Means
Self color is the natural, uncoated finish - no plating, no painting, no zinc - the chain as manufactured. Buyers choose it when they want the chain as made, or will finish it later. Polishing gives a brighter look, and a self color high test chain is one example: grade 43 is supplied self color or polished.
What Galvanizing Adds
Galvanizing puts a zinc layer on the steel to fight corrosion. An electro galvanized chain has a bright, uniform zinc finish for general protection. A hot dip galvanized chain carries a thicker zinc layer for longer protection outdoors. Both are the same steel underneath: the zinc is a coating, not a change to the metal.
The Real Difference
Self color is the steel and nothing else; galvanized is the steel plus zinc. That single difference decides the rest. A self-color chain is bare steel, which rusts if left wet or outdoors. A galvanized chain trades that look for a zinc layer that protects the steel, at the cost of a coating that can be scratched through.
How to Choose
Ask three questions. Indoors and dry? Self color is often enough, and it is the finish when the chain will be painted or processed later. Outdoors, damp or coastal? Galvanizing is the answer - hot dip where exposure is heavy or permanent. Does appearance matter? Polished self color gives a bright natural finish; galvanized a uniform zinc color. Many products are offered in more than one finish: a calibrated link chain is supplied natural as standard, with zinc plated, electro galvanized and hot dip galvanized versions on request. This article covers the two-way choice between bare steel and a zinc coating; for the full range, see our guide to chain surface finishes. On care: a self-color chain is not defective because it rusts - it has no coating, so rust happens when moisture reaches it. Store it dry, and protect it before humid shipping or storage. For the detail, see our guide to self-color chain and rust.
Not a Lifting Chain
One caution applies to both. Self color and galvanized are finishes, not grades: a general purpose chain in either finish is not a grade-marked lifting chain and must not be used for overhead lifting. Lifting needs chain made and marked for it, such as grade 80 or grade 100 with matched fittings. Never weld or repair a load-bearing chain.
Frequently Asked Questions
Is self-color chain the same as galvanized chain?
No. Both start as the same steel, but self color has no coating, while galvanized carries a zinc layer for corrosion protection. Same chain, different finish.
Will a self-color chain rust?
Yes, if it gets wet or stays damp - it has no coating to protect it. That is normal for the finish, not a fault. Keep it dry, or choose a galvanized version.
Which finish should I choose?
Self color for dry indoor use, or where the chain will be painted. Galvanized for outdoor, damp or coastal work - electro for general protection, hot dip where exposure is heavy or permanent.
