Grade 30 Chain Rating

Grade 30 is an excellent all purpose commercial quality chain.

Grade 30 chain rating.

Grade 30 chain is a general purpose chain often used in industrial and agricultural applications. Grade 30 proof coil chain is a heavy grade 30 proof coil chain is a heavy duty high strength welded steel chain. More product details close. Minimum ultimate load is 4 times the working load limit.

Astm states that alloy chain shall be able to elongate a minimum of 20 before fracture 7 3 5. Typical chain uses grade 30. Grade 30 proof coil chain is an excellent low carbon steel chain for general purpose applications. It can be used for load securement but is of less strength than grade 43 chain.

Alloy chain grade 80 or grade 100 should be used for overhead lifting. Grade 43 chain is embossed using a 43 or a g4. With galvanized chain it basically boils down to how much carbon is in the steel. Zinc plated or polycoated yellow.

Grade 30 proof coil self color regular link grade 30 proof coil self color long link grade 30 proof coil electro galvanized regular link grade 30 proof coil electro galvanized long link grade 30 hot dipped galvanized. Not for overhead lifting. General purpose economical chain. Grade 30 aka proof coil has less carbon and is good service duty chain.

The higher the grade the greater the break strength.

G30 300 newton square millimeter 43 511 pound force per square inch. Also called grade 43 high test chain or grade 43 tow chain this is common in the towing and logging industries.

Used in a variety of industries and jobs including light construction agricultural applications and the marine industry. Do not use for lifting people or loads over people. It is designed for use in towing binding logging and other applications requiring high strength chain. To ensure that alloy chain consistently meets this requirement astm requires the use of certain alloying elements in the manufacturing of the steel for alloy steel chain.

Typically used for container securement logging farming towing marine applications and as general purpose utility chain. It is not rated safe for overhead lifting. Frequently used for swing sets borders crowd control and other general applications. The grade number used by manufacturers is an indicator toward the ultimate break strength of chain.
