When it comes to security chain, a question we get a lot is, "Why can't I just use a Grade 100 or a Grade 120 chain?"
People think, "It's strong enough to lift thousands of pounds — nobody's going to get through that."
The trick here is that strength and hardness are very different things. Even though Grade 120 chain is the strongest lifting chain on the market, it's actually much softer than hardened security chain. It’s designed for tensile strength and ductility, not for anti-theft purposes.
On the Rockwell Hardness C scale ("HRC" rating, which is harder than the "B" Rockwell rating), Grade 120 lifting chain has only an HRC of around 41. By contrast, Pewag's security chain is case hardened to get to that 62 HRC rating.
It's also important to know that PEWAG was smart about the way they hardened the chain. Instead of hardening the chain all the way through and making it brittle, they case-hardened the chain between 6% to 10% deep, depending on the size.
You'll hear us call this chain "essentially bolt-cutter proof." We cannot test every pair of cutters on the market, but in our own testing and by customer testimony, we’re comfortable saying that a would-be thief will struggle to cut Pewag’s 10mm or 12mm chain with a pair of common bolt cutters.
Remember too that your chain is only as good as your lock, and Pewag has you covered there, too! They partnered with Viro to offer a specific padlock for each size of chain, and those padlocks are available in a variety of kits. Our customers love kits — it just makes it easier to "one-stop shop" and get all you need in a pre-planned, properly-sized kit.
