What Is G70 Transport Chain? A Buyer Terminology Guide
“G70 transport chain” is a common starting phrase in a cargo-securement inquiry, but it is not the complete purchase specification. The term usually points the buyer toward a transport-chain family and its intended restraint context. The final request still needs to identify the cargo, attachment points, chain configuration, end fittings, finished length, quantity and documentation required for the shipment or fleet program.
How the grade term should be used
The National Association of Chain Manufacturers lists Grade 70 transport chain among the welded steel chain grades covered by its specification. Its guidance is useful for understanding industry terminology, but the public grade description should not be used to invent a product rating, certification or batch result for a particular order.1 Ask the supplier to provide the current product documentation that applies to the proposed configuration.
For a first product review, start with the G70 Transport Lashing Chain page and the wider Lashing Chains category. If the request is for a finished component, compare the G70 Grab Hook Chain Assembly and G70 Slip Hook Chain Assembly options instead of asking only for loose chain.
What a buyer should add to the request
A useful G70 transport chain RFQ should describe the vehicle or cargo setting, such as a flatbed trailer, low-loader, machinery move, steel shipment or project cargo operation. It should then state the required chain size or size range, end-hook preference, finished length, quantity, finish, packaging, labels and destination market. If the customer has a preferred rule or internal specification, attach it to the inquiry rather than assuming that the grade name answers every compliance question.
The chain also needs to work with the rest of the restraint system. Identify the proposed load binder, trailer anchor, lashing hook or replacement interface. If the system includes multiple components, ask the supplier to review their compatibility together. A correct selection is a system decision, not a name-only match.
G70 is not a blanket compliance statement
FMCSA explains cargo-securement requirements through working load limits, tiedown arrangements, blocking and bracing, and commodity-specific rules. The eCFR also sets out general requirements for preventing harmful shifting and describes performance criteria for tiedown assemblies.2 3 These sources help a buyer structure questions, but they do not convert an unverified catalogue item into a blanket compliance certificate.
Before order approval, confirm which rule applies to the cargo, which documents are available for the proposed configuration and which inspection or batch records the customer expects. Keep the application, product identity and documentation trail together so a repeat order can be quoted consistently.
A practical terminology checklist
When writing “G70 transport chain” on an RFQ, add the application, chain format, hook arrangement, finished length, quantity, destination, packing and documentation request. If the item is for a recurring fleet or project, include the existing part reference, drawing or photograph. For an application-led review, see Truck & Flatbed Tie-Down and Heavy Equipment Transport, then send the complete inquiry through the LashLok contact page.
