What is Australian Standard Medium Link Chain, and is it right for your job?

Australian Standard medium link chain is a general-purpose welded steel chain. It offers a balance between the strength of a short link and the flexibility of a long link chain. It’s ideal for lashing, mooring, and agricultural use, but is not rated for overhead lifting.

You now know the basics. But understanding the specific details is crucial for making a safe and cost-effective purchase. Let’s dig deeper into what makes this chain unique and why the standard matters so much for your business.

What are the key specifications for this chain?

Key specifications relate to Australian Standards like AS 2321. They cover material grade, dimensions, and manufacturing quality. The “medium link” specifically refers to the pitch, the internal length of each link, providing a balance between flexibility and strength for non-lifting tasks.

When I source a chain for my distribution business, I have to be incredibly precise. My customers trust my brand, so I trust my suppliers to meet exact specifications. For the Australian Standard medium link chain, I always check a few things. It is important to note that while this chain is made to high standards, it is a commercial chain. It is not intended for overhead lifting.

Material Grades

The grade of the steel tells you its strength. For general-purpose chains like medium link, you’ll often see them made from Grade L steel, as specified in Australian Standards. This grade provides sufficient strength and durability for tasks like lashing cargo, securing farm equipment, or general tie-down applications. It’s the workhorse grade, reliable and cost-effective for jobs that don’t involve lifting.

Dimensions and Pitch

The “medium link” name is all about the dimensions. The pitch, or the inside length of the link, is longer than a short link chain but shorter than a long link chain. This design is intentional. It provides a good middle ground. You get more flexibility than a stiff short link chain, which is useful when you need to wrap the chain around objects. But it’s not so long that it sacrifices too much strength or becomes prone to snagging.

Surface Finishes

The finish protects the chain from rust and corrosion. I choose the finish based on how my customer will use the chain.

• Self-Coloured: This is a basic, black finish. It’s the most affordable but offers minimal rust protection. It’s fine for indoor use or in dry environments.
• Hot-Dip Galvanized (HDG): For outdoor use, especially in marine or coastal areas, HDG is my go-to. The chain is dipped in molten zinc, creating a thick, durable, and highly corrosion-resistant coating.
• Electro-Galvanized: This process uses electricity to apply a thin layer of zinc. It provides some rust protection and a bright, shiny appearance, but it’s not as robust as HDG. It’s a good option for general use where a clean look is desired.

How does the medium link chain compare to the short and long link types?

Medium link chain is the versatile middle ground. Short link offers maximum strength but is stiff. Long links provide great flexibility and are lighter, but have a lower safe working load. Medium link balances these characteristics, making it a great multi-purpose option for lashing and mooring.

I remember a new procurement officer at a company I supply asking me why we stock so many different types of chain. He thought “a chain is a chain.” I had to walk him through the differences because choosing the right one is critical for safety and performance. The best way to explain it is with a simple comparison. Think of it as a trade-off between strength, flexibility, and weight. Here’s a breakdown I often share with my clients to help them make the right choice for their specific application.

The Comparison Breakdown

This table shows the main differences at a glance.

Feature	Short Link Chain	Medium Link Chain	Long Link Chain
Strength (WLL)	Highest	Moderate	Lowest
Flexibility	Low	Moderate	High
Weight	Heaviest	Moderate	Lightest
Kinking/Snagging	Least Prone	Moderately Prone	Most Prone
Common Uses	Anchor chains, lifting slings (if rated), windlasses	Lashing, tie-downs, agriculture, security chains	Fencing, mooring buoys, trailer safety chains

A short link chain has the highest strength-to-size ratio because its links are compact. This also makes it fit perfectly over the gears of an anchor windlass. A long link chain is the opposite. The longer links make it very flexible and lighter per meter, but you sacrifice a lot of strength. It’s great for applications that need length and flexibility but not high load capacity, like a farm gate.

Medium link chain sits right in the sweet spot for many jobs. It’s flexible enough to handle easily but strong enough for serious lashing and securing work. It’s my default recommendation for general transport and agricultural tie-downs.

Why is choosing a certified supplier for this chain so important?

A certified supplier guarantees quality and compliance. I learned this the hard way. It ensures the chain’s material, heat treatment, and load ratings are accurate. This protects you from liability, ensures safety, and upholds your brand’s reputation, especially if you’re a distributor like me.

Early in my career, I was focused almost entirely on price. I thought that if I could save a few dollars per meter on chain, I could increase my profit margins. This was a painful lesson. A reliable supplier isn’t a cost; it’s the foundation of your business.

A Personal Story: The Cost of Unverified Quality

I decided to try a new, very low-cost supplier from a country I hadn’t worked with before. Their price for a large order of medium link chain was too good to pass up. They even sent me a document that looked like a test certificate. I placed the order, feeling proud of the deal I had secured. I was thinking about the profit I would make by rebranding and distributing it in the US market.

The Unraveling

The shipment arrived, and it looked fine visually. I shipped it out to one of my biggest customers, a large agricultural equipment distributor. Two weeks later, I got an angry call. Their quality control team had rejected the entire batch. The link dimensions were inconsistent. Some were closer to long links, and others were short. Worse, one of their teams had a chain snap while tensioning a piece of equipment for transport. Luckily, no one was hurt, but the point was clear: the product was unsafe and unusable.

The Aftermath and the Lesson

The fallout was a nightmare. I had to pay to have the entire shipment returned. I had to refund my customer. Most importantly, I damaged the trust I had spent years building. The few thousand dollars I thought I’d saved cost me ten times that in losses and damaged my reputation. That day, I changed my entire purchasing philosophy. I now only work with suppliers who provide transparent, verifiable certifications, like UU LIFTING. I need to know the materials are traceable and that every batch is tested. Efficient communication and reliable shipping aren’t just bonuses; they are essential. It ensures that the product I sell under my brand is safe, reliable, and something I can stand behind.
