What Should You Consider When Ordering Industrial Chains?

Industrial chains are among the most critical components in applications requiring lifting, material handling, power transmission, conveyor operation, load securing, and continuous operation. Selecting the correct chain directly affects system safety, operating efficiency, and maintenance costs.

Ordering an industrial chain is therefore not a simple purchasing process that can be completed by providing only its diameter or length. The application, working load, chain dimensions, material properties, and environmental conditions must be evaluated together.

This guide explains the technical information that should be determined before ordering a chain and the points to consider when selecting the right supplier.

What Is an Industrial Chain?

An industrial chain is a connection or transmission component designed to operate under demanding conditions such as heavy loads, wear, impact, heat, moisture, and continuous movement.

Depending on the application, industrial chains can be manufactured in different dimensions, alloys, strength grades, and connection configurations. The requirements of a lifting chain are not the same as those of a conveyor or maritime chain.

The main types of industrial chains include:

  • Lifting chains

  • Grade 80 and Grade 100 chains

  • Conveyor chains

  • Power transmission chains

  • Mining and scraper chains

  • Maritime and buoy chains

  • Stainless steel chains

  • Galvanised chains

  • Alloy steel chains

  • Custom-sized and project-specific chains

What Information Is Required When Ordering a Chain?

Essential technical information about the application should be prepared before placing an order so that the correct product can be identified.

1. Intended Application

The first step is to explain how the chain will be used. It may be required for lifting, material handling, power transmission, securing, a conveyor line, or a maritime application.

The intended application is one of the most important factors determining the chain’s strength grade and construction. For example, a chain designed for a conveyor system must not be used in a lifting operation without the necessary technical assessment.

2. Working Load and Load Capacity

The supplier should be informed of the chain’s normal working load, potential sudden loads, and the way in which the system operates. Providing only the approximate weight of the load may not always be sufficient.

The following information should be provided as clearly as possible:

  • Normal working load

  • Maximum load

  • Whether the load is static or moving

  • Possibility of impact or sudden tension

  • Frequency of operation

  • Required safety criteria

For lifting applications, the product’s declared working load limit and the relevant safety requirements must always be verified.

3. Chain Dimensions

When ordering a replacement for an existing chain, measuring only its overall length may not be sufficient. The chain diameter, link dimensions, pitch, and connection configuration must also be considered.

The following measurements may be provided when placing an order:

  • Material or wire diameter

  • Internal link length

  • Internal link width

  • Chain pitch

  • Overall chain length

  • Type and dimensions of end connections

Whenever possible, a technical drawing, product label, or photographs of the existing chain taken from different angles should also be provided.

4. Material and Chain Grade

The chain material directly affects its strength, wear resistance, corrosion performance, and service life.

Depending on the application, the following options may be considered:

  • Carbon steel

  • Alloy steel

  • Stainless steel

  • Galvanised steel

  • Special-alloy materials

  • Surface-treated or coated products

Grade 80 or Grade 100 chains may be considered for lifting applications requiring high strength. However, the grade should not be selected solely according to the load; the complete system and operating conditions must be evaluated together.

5. Operating Environment

Two chains of the same dimensions can perform very differently in different environments. The environment in which the chain will operate should therefore be described in detail.

The following conditions should be specified in particular:

  • Saltwater and high humidity

  • Chemical substances

  • Acidic or corrosive environments

  • High or low temperatures

  • Heavy dust

  • Mud and organic waste

  • Abrasive materials

  • Outdoor conditions

Material and coating selection is particularly important to product life in maritime, chemical, mining, and recycling applications.

6. Operating Speed and Frequency of Use

A continuously operating production line and a lifting system used only at certain intervals do not have the same requirements. The chain’s operating speed, daily working time, start-stop frequency, and available maintenance facilities should be considered during the selection process.

In conveyor and power transmission systems, the chain’s compatibility with sprockets, guides, drums, and other system components must also be checked.

7. Connection Equipment

A chain may be used together with components such as hooks, eye bolts, shackles, master links, swivels, and tensioning equipment.

Connection equipment must be compatible with the chain in terms of dimensions, capacity, and intended use. It should be remembered that the weakest component in the system can affect overall operational safety.

8. Standards, Testing, and Documentation Requirements

Technical standards, tests, and documentation required by the project or industry should be specified before placing the order.

Depending on the project, the required documents may include:

  • Technical product data sheet

  • Material certificate

  • Test report

  • Certificate of conformity

  • Traceability information

  • International inspection or classification society approval

  • Technical drawings and dimensional reports

For lifting, maritime, and offshore projects in particular, documentation requirements should be communicated during the quotation stage.

How Are Industrial Chain Prices Determined?

Industrial chain prices are not based on a single criterion. The main factors affecting price include:

  • Chain type and dimensions

  • Material and strength grade

  • Overall length and order quantity

  • Standard or custom-manufactured construction

  • Heat-treatment requirements

  • Galvanising, painting, or special coating options

  • Testing and certification requirements

  • Connection equipment

  • Delivery time

  • Packaging and shipping conditions

Rather than focusing only on the lowest unit price, the product’s service life, maintenance requirements, safety level, and potential production losses should also be considered. A high-quality chain selected correctly for the application may reduce the total cost of ownership over time.

Standard or Custom-Manufactured Chain?

Standard chains available on the market may be sufficient for many applications. However, certain projects may require non-standard dimensions, special connections, or different material properties.

A custom-manufactured chain may be preferred when:

  • Standard dimensions are incompatible with the system

  • High wear resistance is required

  • The chain will operate at extreme temperatures

  • The operating environment is chemical or corrosive

  • Special machinery connections are required

  • The application involves high impact and intensive operation

  • Custom manufacturing is required by the technical specification

During the custom-manufacturing process, dimensions, materials, heat treatment, surface coatings, and connection design are evaluated according to the project requirements.

How Should You Choose the Right Chain Supplier?

A reliable chain supplier should do more than offer products from a catalogue. The supplier should understand the application’s technical requirements and support the selection of the correct product.

The following points should be considered when choosing a supplier:

  • Technical experience with industrial chains

  • Range of product and material options

  • Ability to provide technical documentation

  • Product traceability

  • Custom manufacturing and engineering support

  • Quality-control and testing processes

  • Delivery capabilities and supply strength

  • After-sales technical support

Selecting the wrong product can cause premature wear, unplanned downtime, equipment damage, and safety risks. Technical suitability should therefore be considered as carefully as price during the purchasing process.
