The DIN 766 standard welded round-link chain pairs a welded round-link construction with high-strength carbon steel, giving the unit a heavy-duty, general-purpose load path for demanding work. Available with electro-galvanized yellow zinc or bright zinc-plated surface treatment, it's built for load-lifting, cargo lashing, towing, rigging, mooring, and construction works where oxidation resistance, wear resistance, and long-term anti-corrosion performance are essential.
Every chain link is manufactured strictly in accordance with the German DIN 766 industrial specification, with smooth, solid, crack-free welding seams produced by automatic welding — see the spec table below to confirm which size fits your application.
Made from high-strength carbon steel, the chain is strong, durable and suitable for heavy-duty applications such as load lifting, cargo lashing, towing, rigging, mooring and construction.
Manufactured strictly in accordance with the German DIN 766 industrial standard, ensuring standardized link dimensions, stable quality and reliable performance.
Available with electro-galvanized yellow zinc or bright zinc-plated finishes, providing excellent oxidation resistance, wear resistance and long-term corrosion protection for indoor and outdoor applications.
Produced with automatic welding technology, each link features smooth and strong weld seams without cracks, improving the overall strength, durability and safety of the chain.
Not every lifting and lashing job calls for a specialized chain. Where a load needs to be lifted, lashed, towed, rigged, moored, or securedon site, a depend able general-purpose chain gets the job done. The DIN 766 standard welded round-link chain is built for exactly that: heavy-duty, reliable performance across load-lifting, cargo lashing, towing, rigging, mooring, and construction works.
Which DIN 766 chain fits your job? If your service runs outdoors or in harsh, corrosive conditions, the electro-galvanized yellow zinc finish provides long-term anti-corrosion protection and wear resistance. If you need a clean, bright surface for indoor general service, the bright zinc-plated finish is the practical choice. If your loads are heavy, step up to larger wire diameters up to 26 mm — see the size table below to match the right chain to your application.

DIN 766 is a heavy-duty, general-purpose chain — built for load-lifting, cargo lashing, towing, rigging, mooring, and construction works where dependable strength matters most.
Select from 6 mm to 26 mm based on your working load and safety margin — heavier loads call for larger diameters. Reference the weight per 100 m to confirm the spec you need.
Working outdoors or in harsh, corrosive conditions? Go with electro-galvanized yellow zinc for long-term anti-corrosion protection. Indoor general service? Bright zinc-plated is the practical, economical choice.
Check inside length, inside width, and outside width against the DIN 766 spec table, and confirm the coil length you require before ordering.
Manufactured strictly to DIN 766 standards for reliable quality.
Made of high-strength carbon steel for excellent durability.
Galvanized surface provides excellent oxidation and corrosion resistance.
Automatic welding ensures strong, smooth and crack-free seams.
Suitable for lifting, lashing, towing, rigging and mooring.
Ideal for both indoor and harsh outdoor environments.
