DIN 5685 Welded Galvanized Steel Chain

Page text

In accordance with the European standard DIN 5685, general-purpose welded galvanized steel chain is produced. Form A is a short-link chain with a low link elongation coefficient. It is not intended for lifting equipment, but is suitable for suspensions, guy wires and other structures under static load. The product consists of repeating round-shaped links made from metal rod using welding.

Design and application features

Carbon steel is used to manufacture welded chain. Zinc coating applied by electroplating or hot-dip galvanizing is used for corrosion protection: it withstands prolonged exposure to atmospheric air, temperature fluctuations and increased humidity. Galvanized chain is suitable for outdoor installation work, including the installation of advertising structures, suspensions and guy wires.

The chain is not designed for impact loads, so it is not used for lifting and transporting loads. The link rod diameter ranges from 2 to 16 mm — this parameter determines the chain size.

Features of welded galvanized chain:

• Low elongation coefficient ensures secure fixation when installing structures.
• Resistance to aggressive environments and atmospheric factors allows the chain to be used outdoors.
• Product weight ranges from 6 to 211 kg per meter of chain, depending on the link rod diameter.
• Short-link chain withstands higher loads than long-link chain.

A common analog is manufactured to DIN 763 — a welded long-link chain with lower load capacity. When selecting, the internal length and width of the link are taken into account, as these determine strength. Welded chains are also manufactured to the Russian standard OST 92-8534-74.

Application options and ordering conditions

The chain is used in rigging operations and outdoor installation, as well as in construction and industry due to its high corrosion resistance. It is also used in private households and agricultural work.

FLOK operates as an official dealer of manufacturers and supplies welded galvanized chains without intermediaries.

The catalogue features a wide range of sizes. FLOK supplies galvanized welded chains of the required diameter within short lead times.
