Grade 30 is a general-purpose chain for barrier, safety chain and suspension type applications. Proof coil is not for overhead lifting or where maximum tensile nor impact strength is crucial.
Grade 70: Transport/Tiedown
Grade 70 Transport Chain is made from boron treated steel which provides a high strength-to-weight ratio. Originally designed for load binding, transport chain is also superior for towing and safety chains.
Grade 70 chain is easily identifiable by its usual gold finish. Unlike general utility chains Grade 70 chain will have an identifier embossed indicating the grade at least every foot.
In order to meet compliance in some jurisdictions. Campbell-Mack Supply also offers a domestic manufactured Grade 70 chain with the breaking strength embossed on the link.
