DIN 763 Long Link Chain | Tested Non-Calibrated German Standard Chain for Marine

Product Specification

DIN 763 Long Link Chain | Tested Non-Calibrated German Standard Chain for Marine and Industrial Use

Product Overview

DIN 763 long link chain is a welded round steel chain supplied for general-purpose holding, securing, barrier, engineering, agricultural, industrial, and selected marine auxiliary applications where a long-link, non-calibrated chain is required. It is commonly selected when the customer needs easier connection with hooks, shackles, or fittings, and when the chain is not intended to run over calibrated pocket wheels, chain wheels, or windlass gypsies.

This page is prepared for DIN 763 tested non-calibrated long-link round steel chain supplied through qualified chain manufacturing partners. The supplied size range is 2 mm to 32 mm, with zinc plated, black painted, hot dip galvanized, powder coated, self-colour, or customized finishes available. Because DIN 763 is not a lifting-chain standard, it should not be used as a chain sling, basket hitch, choker hitch, hoist chain, anchor chain, or certified lifting accessory unless a separate approved specification and certificate are confirmed before order.

Main Technical Parameters

Selection & Inquiry Guide

Step 1: Confirm DIN 763 long link chain and whether the project requires DIN 763:1990-12, a project-specific drawing, or another long-link chain standard.

Step 2: Select chain diameter from 2 mm to 32 mm according to working load, breaking load, link opening, connected fitting size, and required weight per metre.

Step 3: Confirm application: marine general-purpose securing, industrial guard chain, engineering use, agricultural chain, barrier chain, or non-lifting connection use.

Step 4: Confirm finish: zinc plated, hot dip galvanized, black painted, powder coated, self-colour, or customized coating according to corrosion environment and appearance requirement.

Step 5: Confirm order length, packing form, quantity, marking, test document, material certificate, surface finish certificate, and whether third-party inspection is required.

Step 6: Provide delivery destination, required delivery time, intended application, reference photo or drawing, and any customer-specific acceptance criteria.

Structure

Long round steel link | Welded link joint | Non-calibrated pitch | Open long-link geometry | Zinc plated / painted / hot dip galvanized / powder coated finish | Supplied in coil, bundle, drum, or cut length

Load, Testing & Supply Advantages

• The long-link geometry provides more space inside each link, making it convenient for connection with hooks, shackles, pins, and general-purpose fittings when compared with short-link chains.
• DIN 763 is a non-calibrated chain reference. This is important because it should not be selected for equipment that needs calibrated pitch engagement, such as chain wheels, hoists, or windlass gypsies.
• The supplied table gives working load, test load, and breaking load. Keeping these load terms separate helps avoid incorrect use as lifting WLL, proof load, MBL for certified lifting, or anchor-chain test data.
• Flash butt welded / side welded links can be checked by visual inspection, dimensional checking, sample load test, surface finish inspection, and packing inspection according to order scope.
• Surface protection can be selected by environment: zinc plated for general indoor or light-duty corrosion protection, hot dip galvanized for stronger outdoor / marine exposure, painted or powder coated for identification and appearance.
• For marine supply, hot dip galvanized or painted finishes should be selected together with storage environment, salt exposure, handling abrasion, and required service life.
• As a supply item, this chain can be sourced from long-term qualified manufacturing partners with stable batch supply, cost-effective pricing, and optional customer-specific inspection arrangement.
• If the chain is required for lifting, hoisting, chain sling, or safety-critical load suspension, a separate lifting-chain standard such as EN 818 series or project-approved chain specification should be confirmed instead of using DIN 763 by default.

Custom Attributes

FAQ

Q1: Can DIN 763 long link chain be used as a lifting chain sling?

A1: No. DIN 763 long link chain should not be used as a chain sling, basket hitch, choker hitch, hoist chain, or lifting accessory unless a separate lifting-chain standard, approval document, and certificate are confirmed. For lifting use, the customer should specify the required lifting-chain standard and safety factor before quotation.

Q2: What is the difference between DIN 763 chain and calibrated chain?

A2: DIN 763 is a tested non-calibrated long-link round steel chain. It is suitable for general-purpose connection and securing applications, but not for equipment that requires precise pitch engagement, such as hoists, calibrated chain wheels, or windlass gypsies.

Q3: What information is needed before quotation?

A3: Confirm DIN 763 edition, chain diameter, order length, surface finish, quantity, working environment, required packing, certificate requirement, inspection scope, delivery destination, and required delivery time. If the chain will be used in a safety-critical or load-holding application, provide the working load condition and acceptance criteria.
