Chains
Weldless Chains
A non-welded chain made by twisting or bending links together instead of welding, suitable for applications where joint integrity and fatigue resistance matter. Kailipu supplies six weldless chain lines including double loop, DIN5686 knotted, and decorator chains from 3 mm to 20 mm in diameter, so a buyer can cover multiple chain types on one order without sourcing from separate forging or welding specialists.

Who It Is For
Buyers Who Specify Weldless Chains
- Rigging and lifting distributors needing a non-welded chain option for safety-critical or high-cycle applications
- Furniture and fixture manufacturers using decorative chains in lighting, shelving or hanging displays
- Swing set and playground builders requiring durable, non-welded chains for seat connections and frame attachments
- Towing and trailer service providers specifying safety chains with double-loop designs for backup coupling
- Industrial equipment fabricators using weldless chains in machinery where weld zones could crack under stress
- Aerospace and hardware suppliers needing chains with consistent metallurgical properties and no heat-affected zones
Problems Solved
What Weldless Chains Solve on the Job
- A rigging bill of materials missing a chain type because the supplier only produces welded chains and cannot offer a non-welded version
- A chain failing at the weld joint under repeated bending or dynamic load, especially in lifting or towing applications
- No availability of a chain with a knotted or double-loop design for decorative or adjustable tie-down use
- A need for a chain that avoids heat-affected zones from welding, which can reduce fatigue life in cyclic loading
- Lack of a supplier who can provide both standard and custom-sized weldless chains in one order
- Difficulty in sourcing a chain with a clean, smooth finish and no weld spatter for use in visible or sensitive applications

Applications
Where Weldless Chains Are Used
- Hanging pendant lighting or decorative planters in a commercial space where a clean, smooth chain with no weld marks is required
- Connecting swing seats to a playground frame where the chain must withstand repeated dynamic loading and resist fatigue
- Using a safety chain on a trailer with a double-loop design to provide a backup connection in case the main hitch fails
- Creating an adjustable tie-down system for securing cargo on a flatbed where the chain must be looped through a fixed point
- Integrating a non-welded chain into a piece of industrial machinery where weld zones could compromise fatigue life
- Specifying a seamless chain for use in a lifting setup where the absence of a weld is required for inspection or certification

Answers
Weldless Chains FAQ
What is the difference between weldless and welded chain?
Weldless chains are made by twisting or bending links together without welding, avoiding heat-affected zones. Welded chains use fusion welding to join links, which can reduce fatigue life and introduce weld spatter.
What is a double loop chain used for?
A double loop chain allows attachment at both ends, making it ideal for adjustable tie-downs, swing sets, decorative hanging, and safety chains where secure, flexible connections are needed.
What are the common weldless chains?
Common types include double loop chain, DIN5686 knotted chain, and decorator chain. These are used in rigging, decoration, playgrounds, towing, and industrial applications.
What is the working load limit of a weldless chain?
The WLL is based on the minimum breaking load divided by the design factor. A standard 4:1 design factor applies unless otherwise stated. The WLL is stamped on the chain and listed in the product data.
Do you supply material test certificates for weldless chains?
Yes. Material Test Certificates to EN 10204 3.1 are issued with the batch on request. Every batch undergoes proof load testing, dimensional checking, and breaking strength validation.
Can you make custom weldless chains?
Yes. Custom sizes, link patterns, and chain lengths can be built to your drawing. Send the dimensions and configuration for a quote. We support OEM and private label marking.
What materials are available for weldless chains?
Available in Grade 43, Grade 70, and Grade 80. Grade 80 is for high-stress lifting and rigging. Grade 43 is for general utility. Material grade is stamped on the chain.
