G43 vs G70 Transport Chain: A Procurement-Focused Comparison
A G43 versus G70 transport chain question should begin with the application and the required documentation, not with a request to substitute one label for another. Both terms appear in cargo-securement conversations, but a finished buying decision also depends on the cargo, anchor points, hook arrangement, tensioning method, length and applicable requirement.
Clarify what the buyer means by “transport chain”
Ask whether the request is for loose chain, a chain assembly or a complete restraint set with hooks and a binder. The Lashing Chains category is the correct starting point for loose chain families, while Lashing Chain Assemblies is the better route when the customer needs a finished length and selected end fittings.
The catalog includes a G43 lashing chain and a G70 transport lashing chain. The product pages are intentionally written around selection questions rather than unverified numerical claims. A supplier should confirm the current technical information for the exact size, finish, configuration and market.
Compare the system interface
The chain must connect to a suitable vehicle anchor point and cargo attachment. Record the hook style, whether a latch is requested, whether shortening is needed and how the chain will be tensioned. The lashing hooks range includes grab, slip, C and weld-on configurations, while load binders provide the tensioning side of the system.
A request that only says “G43 chain” or “G70 chain” leaves important decisions unresolved. A better request states: chain family, chain size to be confirmed, finished or cut length, end fittings, tensioning method, quantity, intended cargo and any customer or regulatory reference. That format makes it easier to compare like with like.
Treat standards as a verification step
NACM’s public welded steel chain specification page describes a range of commercial chain grades, including Grade 43 high-test chain and Grade 70 transport chain, and directs users to consult the chain manufacturer for additional recommendations.1 This is useful terminology background. It is not a substitute for the technical documentation of the specific product being quoted.
FMCSA’s cargo-securement guidance also distinguishes between the overall securement system and the individual tiedowns, and it discusses working load limits, tiedown counts and blocking or bracing.2 For that reason, a buyer should evaluate the chain, hooks, anchor points and tensioning method together.
When to ask for an assembly instead
Choose a pre-assembled product when the customer wants a repeatable finished configuration and does not want to source compatible hooks separately. LashLok offers G70 grab-hook chain assemblies and G70 slip-hook chain assemblies as starting points. Confirm the exact assembly details with the supplier before ordering.
If the application is a machinery move or another heavy-cargo scenario, describe that use through the cargo securing applications hub. A complete application description helps the supplier review compatibility, packaging and documentation instead of treating the grade name as the only decision.
