Frequently Asked Questions
What is G80 lashing chain used for?
It is used to lash and secure cargo on trucks, trailers and flat racks, and for lifting within its rated working load limit. Match the grade and capacity to the load and the lashing point.
What does the G80 marking mean?
It identifies a grade 80 lifting chain made from alloy steel. This product follows GB/T 20947-2007 / ISO 3077:2001, with a safety factor of 4 times and a manufacturing proof force of 2.5 times. Because it is a heat-treated lifting grade, it is stronger than a commercial general purpose chain of the same diameter.
What sizes and working load limits are available?
From 6 mm to 32 mm diameter, with working load limits from about 1.12 t to 31.5 t. The heavier the load, the larger the diameter - tell us what you need to secure and we will confirm the size.
What finish is the chain supplied in?
This product is supplied blue painted. If your site or climate calls for a different finish, tell us the conditions and we will confirm what we can offer for your order.
