This extended pin chain is manufactured according to the German DIN5685 standard, which ensures high quality and precision. It is available in two types: A-type short links and C-type long links. Short links are closely spaced, making them ideal for guardrails and other protective applications where items need to be secured. Long links have wider spacing, providing flexibility for fences or anti-loss devices. Chain diameters range from 2 mm to 13 mm, allowing you to select the appropriate size for your needs.
Important
This extended pin chain is not designed for lifting or suspending heavy objects. It is intended solely for protective applications, such as roadside guardrails, machine safety netting, or anti-loss chains for valuables. Using it for lifting or suspension could be dangerous, and we must emphasize this limitation.
We maintain strict control over the chain material
Carbon content is kept within 0.25%, manganese content no more than 1.4%, and phosphorus and sulfur contents no more than 0.045%. This ensures toughness and reliability. The chain is flash butt welded, producing welds with strength exceeding 80% of the base material. The welds are smooth and burr-free, allowing links to rotate freely without jamming.
Every batch undergoes detailed inspection according to German standards
We measure pitch, inner width, and outer width to ensure accurate dimensions before shipment. This guarantees that the chain can be installed directly with your protective equipment without modification.
Surface treatments are available in galvanized, painted, or natural finishes
For indoor use, the natural finish is sufficient. For outdoor or humid environments, we recommend galvanized chains for corrosion resistance.
When used correctly, this chain provides reliable safety for guardrails, fences, and anti-theft applications. Its design prioritizes protective performance, and all manufacturing processes follow strict quality control standards to ensure professional reliability.
