What is the difference between Grade 43 and Grade 70 chain?

Grade 70 chain is about 20 percent stronger than Grade 43. It is made from heat-treated carbon steel that is incredibly sturdy and durable. Grade 70 industrial chains typically come in a gold chromate finish for easy identification – as well as protection from abrasion and scratches.

Is Grade 43 chain better than Grade 70?

Grade 70. Approximately 25% stronger than Grade 43, Grade 70 is ideal for securing and towing large or heavy loads for road transport applications in the trucking, logging, and highway construction industries.

What is Grade 43 chain used for?

Grade 43 chain (G43 of G-4) is designed for use in load binding, towing, logging, and other applications requiring high strength. It is made from carbon steel and is available in bright galvanized or zinc-plated finishes. Grade 43 chain is proof tested and should NOT be used in overhead lifting.

What is Grade 70 chain used for?

Also known as “Transport Chain,” Grade 70 chain is most commonly used for tie down and load securement applications for trucking and other cargo. While Grade 30 and 43 chain can also be used for load securement, Grade 70 chain provides a stronger, more durable option with a much higher strength-to-weight ratio.

What is the best grade of chains?

Grade 100 chains are the strongest among readily available chains.

What Are the Different Grades of Chain?

Is Grade 43 chain good?

Carbon steel chains, like Grade 30, 43, and 70, cannot handle the stress/Newtons required for tasks such as overhead lifting. Meanwhile, alloy steel chains – like Grade 80 and higher – can handle that kind of tensile force and thus are recommended for any heavy-duty lifting.

How strong is Grade 43 chain?

Grade 43 chain is a steel chain that possess greater tensile strength than Proof Coil Chain. Grade 43 Chain typically has a 50% higher working load limit than Proof Coil or Grade 30 Chain. G43 chains are also referred to as High Test Chain, Grade 40, Spectrum 4 or System 4.

How good is Grade 70 chain?

Grade 70 is a high quality, high strength heat treated chain that is becoming the standard for load securement. Grade 70 or Transport chain offers greater hardness and ultimate durability. Transport chain is primarily used and tow and binder chain in agriculture, construction, industrial, trucking and forestry.

Is Grade 70 chain hard to cut?

Grades 70, 80, and 100 are among the hardest and toughest available. Here's the kicker, though. We're talking chain that costs $10 to $22 per foot; it's likely to be more valuable than what you're chaining down, a fact that might not be lost on an enterprising thief, who might just make off with the chain itself!

Can you lift with Grade 70 chain?

Grade 70 Transportation Chain

G70 chain is the rigging chain of choice in the trucking and transportation industry and is used as tie-downs on over-the-road trailers. Grade 70 steel rigging chain is not approved for overhead lifting and is never to be used for such.

What is G43 chain?

More strength with lower weight makes G43 High Test chain popular for boats with electric windlasses. An excellent choice for ground tackle, Grade 43 chain is about 35% stronger than conventional BBB chain, which allows you to save weight without sacrificing anchoring security.

What is grade 43 steel?

Grade 43 is an old number for structural steel acc. BS. It is now called S275. Tensile strength 410-560 Mpa. Yield 275 Mpa (for tk up to 16mm)

What is the heaviest grade chain?

Grade 100. A high strength, heat-treated alloy chain. Primarily used as a sling component for overhead lifting.

What color is Grade 70 chain?

It's gold or yellow chromate finish makes it easy to recognize and identify, which is particularly useful in over-the-road jobs where cargo is subject to inspections. It's also embossed with 7, 70, or 700 for easy identification. Grade 70 chain should never be used for overhead lifting.

What size chain do I need to tie down my tractor?

Typically, grade 70 chain is the standard for tie down chain. Other chain grades such as 80, 100, and 120 can also be used, but aren't as popular.

What chains Cannot be cut?

A heavy-duty, hardened steel chain with hexagonal links thwarts nearly every thief with a bolt cutter. Hexagonal links (or square or trapezoidal) make it impossible for bolt cutters to get a grip.

Can Grade 43 chain be cut with bolt cutters?

Cheap Chain Cuts Easily

bolt cutter to cut through a Grade-43, home center 3/8-in. high-test, hot-dipped, galvanized zinc link. You will not likely stop thieves with these chains; they may not even break a sweat!

What type of chain Cannot be cut?

A Resistant, Bolt Cutter Proof Security Chain

By being the toughest chain, we mean the Pewag chain is the hardest chain to cut with bolt cutters due to its hardened, squared steel chain.

Will Grade 70 chain rust?

G70 chains are made from a higher strength, heat-treated carbon steel and have a load rating approximately 20 percent higher than Grade 43. The gold chromate coating offers them more resistance to rust and corrosion. These chains have become the most common grade of chain used on flatbeds.

What is a grade 100 chain rating?

Grade 100 Chain has a 20 percent increase in working load limit as compared to a similar size chain in Grade 80. This allows you to reduce the size of the chain depending on the working load needed. Grade 100 chains are also referred to as Grade 10, System 10, Spectrum 10.

Is all grade 70 chain gold?

Grade 70 chain is manufactured in heat-treated carbon steel. Also known as "trucker's chain," people use grade 70 as tie-downs on over-the-road trailers. Never use this chain for overhead lifting. This type generally features a gold chromate finish so it's easy to recognize.

Can bolt cutters cut grade 70 chain?

This chain is common in the US and can be identified by the term "Grade 70" and the typical gold color. The 5/16" size can BARELY be cut by 36" bolt cutters with a 180lb guy bouncing all his weight on the handle for about 20-30 seconds, including 1 or 2 chain repositions.

What is the strongest chain made?

If you need maximum strength and low cost, then steel is the best option. If you need corrosion resistance and high strength, then stainless steel is the best option. Its as strong as steel but it costs a lot more. If light weight is important, but maximum strength isn't, then aluminum or plastic are good options.

How do I tell what grade my chain is?

Just look for the “L” and then the number after it. Each number following the “L” corresponds with a grade of chain. On grade 70 this can also show that the chains are DOT approved!
