DIN 5685 Long Link Chain

Name: DIN 5685 Long Link Chain
Brand: H-Lift Industries Co Ltd
SKU: 708014
Availability: InStock
Rating: 5 (1 reviews)

No.708014

The H-Lift DIN 5685-C Round Steel Long Link Chain is a general-purpose, non-calibrated chain manufactured to German DIN standards, featuring elongated links suitable for lashing, fencing, and light-duty applications.

Available in nominal sizes from 2mm to 13mm, with breaking loads up to 53 kN (approx. 5.4 tons).
Long link design (Form C) offers lighter weight per meter compared to short link chains, making it cost-effective for non-lifting uses.
Typically supplied in galvanized or self-colored finishes for basic corrosion protection.
Intended for static loads and general utility; not approved for overhead lifting applications.

Technical Data
Chain Grade Guide

The DIN 5685-C Long Link Chain is a welded, round steel commercial chain manufactured to German DIN standards. Its elongated "Type C" link design makes it lighter per meter than short link chains and provides larger openings, making it exceptionally easy to attach hooks, shackles, and carabiners anywhere along its length.

⚠️ SAFETY WARNING: NOT FOR OVERHEAD LIFTING.
This chain is not calibrated for precision hoists and is strictly a commercial, general-purpose chain. It must never be used for overhead lifting. Use Grade 80 or Grade 100 chains for lifting applications.

🔗 Long Link Advantage

The elongated link profile (Type C) allows hardware to be passed through the links easily. It also offers a lower weight-per-meter, making it a cost-effective choice for long runs.

⚙️ Material Options

Available in various grades including Carbon Steel (Q195, Q235), High Carbon Steel, Manganese Steel, or Marine-Grade Stainless Steel (AISI 304/316).

🛡️ Corrosion Resistance

Customize your protection level. Choose from Hot-Dip Galvanized, Electro-Galvanized, Blackened, or Plastic Coated finishes to suit your specific environmental needs.

🛠️ Versatile Applications

Ideal for a wide range of non-lifting tasks including animal tethering, garden/gate chains, security barrier chains, agriculture, and marine deck securing.

ℹ️ Size Range: Offered in wire diameters ranging from 3mm to 13mm.

Q: What is the difference between DIN 5685 Type A and Type C? A: Type A is a short link chain, which is more flexible and handles lateral forces better. Type C is a long link chain, which is lighter per meter and has larger openings, making it much easier to attach hooks or shackles directly through the links.

Q: Can I use DIN 5685 chain for overhead lifting? A: No. DIN 5685 chains are commercial, general-purpose chains. They are not rated or calibrated for overhead lifting. For overhead lifting, you must use Grade 80 or Grade 100 alloy steel chains.

🚫 Carbon Steel Chain Grades 30, 43, 70
Used for tie-downs, towing, and securement.
NEVER used for overhead lifting.

✅ Alloy Steel Chain Grades 80, 100
Specifically designed and heat-treated for
Overhead Lifting and Sling Assemblies.

How is "Grade" Calculated?

The grade number represents the chain's tensile strength (mean stress value). It is calculated by dividing the tensile force (Newtons) by the cross-sectional area of the two links ($mm^2$).

As the Grade Increases:

The material becomes harder and more resistant to abrasion.
The Strength-to-Weight ratio increases (more lifting power, less weight).
The Working Load Limit (WLL) increases significantly.

Chain Grade Comparison Matrix

Grade	Material	Primary Applications	Overhead Lift?
Grade 30 (Proof Coil)	Low Carbon Steel	Light duty, logging, playground equipment, simple barriers.	NO
Grade 43 (High Test)	Carbon Steel	Towing, general utility, load securement. Stronger than G30.	NO
Grade 70 (Transport)	Heat-Treated Carbon	Heavy Duty Securement. Standard for trucking tie-downs. Identified by Gold/Yellow finish.	NO
Grade 80 (Alloy)	Alloy Steel	Standard Lifting Slings. High ductility (stretch) to absorb shock.	YES
Grade 100 (Premium)	Alloy Steel	Heavy Lifting. 25% stronger than G80. Harder surface for abrasion resistance.	YES

Common Problems & Critical Safety Warnings

Even with the correct grade, misuse can lead to catastrophic failure. Ensure your riggers are trained to avoid these three common hazards:

⚠️ 1. The Hoist Chain Trap

A frequent and dangerous mistake is using the load chain inside a hoist to wrap around a load.

The Design: Hoist load chain is hardened specifically to fit internal sprockets (tight tolerances). It lacks the ductility (stretch) required for a sling.
The Risk: Wrapping it around a load deforms the links. When retracted, the deformed links can snap or destroy the internal hoist mechanism.

⚠️ 2. The "Gold Chain" Error

Using Grade 70 (Gold) chain for overhead lifting is a common error because the chain looks robust.

Why it Fails: Grade 70 is heat-treated for abrasion resistance (for rubbing against truck beds), not for the elongation needed to absorb the dynamic shock of a crane lift. It may snap suddenly without warning.

⚠️ 3. General Neglect

Alloy chain is tough, but not invincible. Proper storage and inspection are vital.

Corrosion: Leaving chain on damp shop floors promotes pitting and stress corrosion cracking.
Inspection: Chains must be inspected regularly for nicks, gouges, and elongation (stretching).
