Hot dip galvanized chain

Hot-dip galvanized steel chains are made from carbon steel grade C50 or A8 with tensile strength of 800–900 N/mm². Wire diameters range from 6 to 30 mm with a pitch length approximately 3.2 to 3.6 times the wire diameter. Minimum breaking force varies from 25 to 550 kN depending on chain size. Working Load Limit is calculated with a 4:1 safety factor for general use and 5:1 for critical operations. The galvanizing process involves immersion in molten zinc at 450°C. Coating thickness is guaranteed between 50 to 100 microns per ISO 1461 standards.

The chain structure features resistance welded links with full circumferential flash butt welding. Links are designed in a standard oval shape with a 60-degree internal attachment angle for even load distribution. Post-heat treatment surface hardness is maintained between 30 to 35 HRC Rockwell C. The galvanized coating provides uniform coverage with high adhesion Grade 1 and scratch resistance. These chains are suitable for operating temperatures from –40°C to 200°C in humid and corrosive environments. Production complies with ISO 1834 Grade 8 and DIN 766 standards for industrial, marine, and agricultural applications.

G43 galvanized chain

Iron chains produced by using and bending cut iron wires are often found in G30, G43 grades in the market. This iron chain is produced by cold forging method and after bending, it is welded at any point and to produce each grain of chain. Galvanized iron chain is used for purposes other than lifting loads, and low carbon steel alloy is used in its production, which has high hammerability and has a smooth surface.
