If you are sourcing oval link chain for jewelry production, pet products, retail display or craft kits, the difficult part is rarely finding “a chain”. It is finding a supplier who keeps the same wire diameter, the same link pitch and the same plating thickness across the second, third and tenth order.

Nantong Hechang Metal Products Co., Ltd. has been making chains since 2017 in Nantong, Jiangsu — about 1.5 hours by road from Shanghai. Our oval link range runs from 2.8 mm to 6.3 mm wire, in mild steel, stainless steel and brass, with finishes from plain bright to electro-galvanized and colored plating. This page covers what the specification means, how to compare quotes, and what to send us so the first sample matches what you intended.

What an Oval Link Chain Actually Is

An oval link chain is built from wire formed into an elongated ring, longer than it is wide, then interlocked with the next link. Depending on the end use, the links are welded closed or left unwelded so the chain stays flexible and can be shortened by hand.

Buyers describe the same product in several ways: oval link chain, oval chain, elongated link chain, long link chain, and sometimes paperclip chain when the link is stretched far past the normal 2:1 ratio. Whatever the search term, what matters at the quotation stage is four numbers: wire diameter, inner link length, inner link width, and link count per meter.

Compared with a round link of the same wire gauge, an oval link has a longer opening. That changes how the chain hangs, how it reads visually, and how much wire goes into each meter. A round link looks denser and more mechanical; an oval link looks lighter and more fluid at the same wire size, which is why it dominates necklaces and bracelets where the chain itself is the design.

Why Buyers Specify Oval Links

Drape. A longer link allows more articulation per unit length. A 3 mm oval chain bends into a smoother curve than a 3 mm round chain, so necklaces sit flatter on the collarbone and bracelets do not push out at the wrist. Customers can feel the difference between two chains that weigh the same.

Visual weight control. Elongated links reflect light along a longer strip. At 2.8 mm wire the chain reads fine and delicate; at 4.0 mm the same geometry reads as a statement piece without becoming heavy. Designers move between “everyday” and “bold” versions of one collection without changing the clasp or the plating line.

Easier assembly and repair. The wider opening accepts pendants, clasps and connectors more easily, and end users can shorten the chain with a small tool. For brands selling adjustable lengths or repair kits, that is a practical advantage.

Standard Size Range

The codes below are the trade references we produce most often. The figure is the wire diameter in millimeters; inner link length and width are produced to your drawing or sample.

Sizes outside this table are possible. Send the wire diameter, the inner length and width, and the tolerance you can accept. We will confirm whether the geometry can be produced on our equipment before quoting, so you do not pay for a sample that cannot be repeated in bulk.

Выбор материала

Mild steel (low carbon wire). The standard base for galvanized and plated decorative chain: cheap per meter, easy to weld, strong enough for hanging, tag and pet use. It needs a coating to resist rust, so the finish decision matters as much as the material.

Stainless steel 304. For jewelry, pet products and outdoor display where the chain sees humidity, sweat or rain. It holds its surface without plating and is the usual answer when a buyer wants a non-rusting chain at a workable price.

Stainless steel 316. The step up for coastal installations, marine display, poolside fixtures and skin-contact pieces. It costs more and is normally ordered in smaller volumes.

Brass and copper alloys. Mainly a base for gold-colored plating, and for jewelry that needs a warm tone without a heavy gold layer. Brass also polishes well on fine links.

One rule worth stating plainly: stainless steel is a corrosion grade, not a strength grade. A 304 chain and a mild steel chain of the same wire diameter behave similarly under load, and neither is a certified lifting sling.

Finishes and What to Write in the Specification

• Bright / self-color — cleaned and polished, no coating. Suits stainless and jewelry that will be plated downstream.
• Electro-galvanized — zinc coating for general rust protection. Specify coating weight or salt-spray hours if the chain is stored outdoors.
• Plating (nickel, gold, rose gold, black, gunmetal) — specify color by sample or Pantone reference and plating thickness by number.
• Powder coating — for larger links such as 4GA, where a colored matte finish is wanted.
• PVD — thin, hard, color-stable coating for jewelry that must survive daily wear.

Plating causes most complaints, and nearly all of them trace back to an unclear specification. “Gold color” is not a specification. “Gold tone matching sample A, 0.1 micron minimum, 24-hour salt spray, no blistering” is. We test adhesion and corrosion before shipment and report the result with the batch, so the standard you approve is the standard you receive next time.

Quality Control at Five Points

1. Incoming wire. Diameter and tensile checked against the purchase specification; a 3.0 mm order should not arrive as 2.9 mm.
2. Link geometry. Inner length, inner width and pitch measured against the approved sample, with the tolerance agreed in writing.
3. Weld integrity. Welded links are pull-tested and checked for missed welds, under-weld and burn-through. Unwelded jewelry chain is checked for consistent gap so links do not open in use.
4. Coating. Plating thickness, adhesion and salt-spray performance verified to the agreed standard; galvanized batches checked for uniform coverage and no white rust.
5. Length and packing. Meters per spool or weight per coil verified, ends finished as requested, cartons checked against the packing list.

We work to an agreed AQL plan and can arrange third-party inspection before shipment. If you already have a rejected batch, send a photo of the defect — a missed weld, a snapped link, plating peel at the bend — and we will tell you which point failed.

Where Oval Link Chain Is Used

Jewelry and fashion accessories

Necklaces, bracelets, anklets, body chains and earring drops. The 2.8–3.2 mm range is the working size; gold-, silver- and rose-gold tones match most collections. Supplied by the meter, by the spool, or cut to fixed lengths with clasps fitted.

Bags, garments and accessories

Handbag and shoulder strap chain, key chain, luggage tag chain. The 4.0 mm and 6.3 mm links carry the visual weight a bag needs; nickel or gunmetal finishes are usual.

Pet products

Tie-out chain, lead extension, collar chain and small-animal chain. Galvanized and powder-coated finishes are standard. Load needs differ by animal size, so verify by physical test rather than by nominal size.

Retail display and craft supply

Hanging sign chain, price-tag chain, window display chain, and small spools for bead shops, kit packers and online jewelry-supply sellers. Link consistency matters more than strength here. Retail-ready spools with clean ends and accurate meter counts sell better than bulk coils repacked at the destination.

Chains in this range are decorative and utility products. They carry no working load limit and are not rated for overhead lifting unless a batch is specifically tested and certified.

What to Send for an Accurate Quote

A quote is only as good as the specification behind it. Send these six items and the first reply will usually be a price, not a question:

1. Drawing or sample. Inner link length and width, wire diameter, and the tolerance you accept. A photo with a ruler in frame is enough to start.
2. Material. Mild steel, 304, 316 or brass.
3. Finish. Color reference, plating thickness and corrosion requirement.
4. Form of supply. Spool, coil, cut length, or chain with clasp fitted.
5. Quantity and packing. Total meters or kilograms, meters per spool, carton or pallet preference.
6. Delivery. Destination port and the date you need the goods, not the date you order.

Samples usually take about 7–10 days for standard geometries; custom plating and new link dimensions take longer. Bulk production normally runs 20–30 days after sample approval, confirmed on the proforma invoice.

How Oval Link Chain Is Priced

Five variables move the number, and it helps to know which one you are paying for:

• Wire diameter. Cost rises roughly with the square of the diameter, so 4.0 mm is far from twice the price of 2.8 mm per meter.
• Elongation ratio. A very long link needs more careful forming and slower output.
• Material. 316 stainless can cost several times mild steel at the same size.
• Finish. Plain bright is the baseline; plating adds material and handling cost, and thicker plating adds more.
• Order size and packing. Small runs, retail spools and mixed-color batches cost more per unit than one large coil.

When comparing suppliers, ask for price per meter and price per kilogram, plus the weight per meter. A quote that looks 15% cheaper per meter can be 10% lighter per meter — a different product, not a better price.

Packing and Shipping

Chain is wound on spools or coiled and tied, then bagged and boxed: inner poly bags with desiccant for plated goods, standard export cartons, pallets on request. Nantong is about 1.5 hours from Shanghai, with Ningbo and Shanghai as the usual loading ports. FOB, CIF and express air for samples are all workable.

Why Buy From Hechang

We are a chain factory, not a trading company. Since 2017 we have produced jack chain, double loop (knotted) chain, welded chain, sash chain, single suspension chain, stainless steel chain, electro-galvanized animal chain and decorative chain — oval link chain sits inside the same workshop. Link geometry and welding are decided on our own equipment, so a change approved in the sample can be repeated in production.

Custom work is routine. Send a drawing, a sample or a photo of a competitor’s chain, and we will produce to that specification and tell you where the tolerance has to move to keep the price sensible. Every batch ships with the inspection record for the standard you approved.

ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ

What is your MOQ for a custom oval link chain?
MOQ depends on size, material and finish. Stock sizes in standard finishes start lower than custom plating runs, and small trial quantities are possible for sampling. Send your target quantity and we will quote the lowest workable MOQ rather than a generic figure.

Can you match a chain sample I already sell?
Yes. Send the sample or a clear photo with a ruler. We measure wire diameter, inner length, inner width and link count per meter, then confirm whether the geometry can be reproduced and what tolerance applies.

Do you supply welded and unwelded oval links?
Both. Welded links are the default for strength and for anything that will be pulled or hung. Unwelded links suit jewelry that must stay soft and be shortened by hand, provided the gap is controlled.

Will stainless steel oval link chain rust?
304 resists normal indoor and outdoor humidity; 316 is better for coastal air, salt water and poolside use. Plated mild steel corrodes once the coating breaks at a weld or a bend, which is why plating thickness and adhesion testing matter.

Can I get small spools for retail or jewelry kits?
Yes. We supply 1 m, 5 m, 10 m or 25 m spools with clean cut ends, a printed label area and retail-ready packing. Tell us the spool size and label requirement.

Is your oval link chain rated for lifting? No. These are decorative, jewelry, pet and hanging chains. They carry no working load limit and must not be used as lifting slings or for overhead suspension of people or heavy loads.

How fast can you quote? With a complete specification, usually within one working day. If a dimension is missing we will ask, because guessing at link geometry is how samples get rejected.
