Norwegian Standard Link Chain

Name: Norwegian Standard Link Chain
Brand: H-Lift Industries Co Ltd
SKU: 708017
Availability: InStock
Rating: 5 (1 reviews)

No.708017

The H-Lift Norwegian Standard Link Chain is a welded round steel chain manufactured to meet Norwegian industrial specifications, designed for reliable performance in marine, agricultural, and general-purpose applications.

Manufactured to Norwegian market standards, ensuring consistent link dimensions and quality for various commercial and industrial uses.
Constructed from mild steel and typically available in hot-dip galvanized, electro-galvanized, or self-colored finishes for protection against corrosion in outdoor environments.
Offered in a range of wire diameters from 3.5mm to 19mm to accommodate breaking loads from 0.5 tons up to 14.0 tons.
Strictly intended for static loading, lashing, securing, and general utility; it is not approved or certified for overhead lifting operations.

Technical Data
Chain Grade Guide

The Norwegian Standard Link Chain is a highly robust, short-link commercial chain manufactured specifically to meet the historical and functional demands of the Scandinavian maritime industry. Forged from low-carbon steel and available in heavy-duty protective finishes, it is the preferred choice for commercial fishing vessels, gear rigging, and severe marine mooring environments.

⚠️ SAFETY WARNING: NOT FOR OVERHEAD LIFTING.
This chain is a commercial-grade product designed strictly for securing, lashing, and marine mooring. It is NOT rated, calibrated, or certified for overhead lifting operations or the dynamic suspension of loads.

✅ Standard Compliance

Manufactured specifically to meet the precise dimensional and strength requirements of the Norwegian National Chain Standard, ensuring compatibility with regional maritime hardware.

🔗 Short Link Design

Often referred to as "Norwegian short link," this welded round-link pattern is incredibly compact and robust. Its geometry makes it highly resistant to tangling and well-suited for tight mechanical spaces.

🛡️ Extreme Corrosion Resistance

Forged from low-carbon steel. To combat the severe conditions of the sea, these chains are available in highly corrosion-resistant finishes including hot-dip galvanized, zinc-plated, black painted, or chromate.

⚓ Maritime Applications

The go-to chain for harsh marine environments. Widely used on commercial fishing vessels, aquaculture farms, and workboats for heavy-duty gear rigging and dependable mooring lines.

Q: What makes the Norwegian Standard chain different from a DIN standard chain? [Image comparing the link pitch (inside length) of Norwegian Standard chain vs DIN 766 chain] A: The Norwegian Standard specifies a unique set of dimensional requirements (the exact inside length and width of the links) that differ slightly from German (DIN) standards. It is specifically engineered to meet the historical and functional demands of the Scandinavian commercial fishing and maritime industries.

Q: Should I choose hot-dip galvanized or zinc-plated finish for marine use? [Image cross-section illustrating the thick protective layer of hot-dip galvanizing vs thin electro-zinc plating] A: For any exterior marine application, especially on fishing vessels or for mooring lines, you should always choose hot-dip galvanized. The zinc coating applied during the hot-dip process is much thicker than standard zinc plating (electro-galvanizing) and provides significantly better long-term protection against severe saltwater corrosion.

🚫 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).
