FAQ

What is Grade 43 chain?

Grade 43, also known as G43 High Test chain, is a high-strength steel chain built to handle tough tasks. It’s commonly used in industries like construction, shipping, and transportation. Whether you’re securing equipment, towing, or lifting, Grade 43 gives you the strength and reliability needed for heavy-duty work. It’s the go-to choice for businesses looking for a strong, cost-effective solution.

Grade 43 vs Grade 70 chain: what’s the difference?

Both Grade 43 and Grade 70 chains are made for heavy-duty jobs, but Grade 70 is stronger. It’s designed for securing cargo in transportation, while Grade 43 is great for general towing and lifting. If your work requires maximum strength for huge loads, you might lean toward Grade 70. But if you’re looking for a dependable, cost-effective option for everyday tasks, Grade 43 fits the bill.

What is the G43 chain rating?

The G43 chain, or Grade 43 high-test chain, is rated with a working load limit (WLL) of 3.25 times its weight. This rating ensures it can safely handle heavy-duty lifting, towing, and securing operations. The exact WLL depends on the chain’s diameter, but businesses can rely on G43 for a wide range of applications where strength, durability, and reliability are required.

How strong is G43 chain?

Grade 43 chain provides exceptional strength for a variety of industrial tasks. Typically made from carbon steel, its tensile strength varies depending on the diameter of the chain, but it can handle loads ranging from 3,000 to 9,000 pounds per link in some cases. It’s perfect for medium to heavy-duty tasks like securing equipment or towing trailers in construction or transportation.

How does Grade 43 chain perform in extreme temperatures?

Grade 43 chain performs well in a variety of temperatures, but like most steel chains, it can become brittle in extremely low temperatures. It’s best used within the typical operating range of -20°F to 400°F. If you’re working in environments that experience extreme heat or cold, consider using chains specifically designed for such conditions, or check with the manufacturer for temperature-specific ratings.

Can I use Grade 43 chain for towing vehicles?

Yes, Grade 43 chain is ideal for towing vehicles and other equipment. It’s often used in the transportation industry for towing trailers and heavy-duty trucks. Always ensure that the working load limit (WLL) of the chain exceeds the weight of the vehicle you’re towing, and ensure proper attachment points for secure towing.

What maintenance does Grade 43 chain require?

To maintain the longevity and performance of your Grade 43 chain, follow these key steps:

Clean regularly: Remove dirt and debris to keep the chain functioning smoothly.
Lubricate: Apply oil or grease to prevent rust and ensure the chain moves freely.
Inspect for wear: Check for any signs of wear or damage to avoid failure during use.
Use anti-corrosion treatments: If used in marine or high-corrosion environments, apply protective coatings to extend the chain’s lifespan.
