Stainless steel lifting rings: corrosion-resistant lifting points for professional applications

Safe and flexible lifting in demanding environments

When lifting machines, structures and other heavy loads, the working load is not the only important factor. In humid, corrosive, chemical or marine environments, the material of the lifting point must also be able to withstand the conditions in which it is used.

The stainless steel lifting rings from OpenSupply are designed for applications where corrosion resistance and reliable lifting performance are important. The range consists of various Codipro lifting rings made from 316L stainless steel, with both single and double swivel versions and male and female configurations.

Thanks to their swivel design, the lifting rings can adapt to the direction of the load during lifting. This makes them suitable for axial lifting, angled lifting, tilting and rotating loads.

The result: a professional and corrosion-resistant lifting point for applications where standard steel lifting rings are not the most suitable choice.

Why choose a stainless steel lifting ring?

Stainless steel is particularly suitable when a lifting ring is exposed to moisture, chemicals or other conditions where corrosion may become a concern.

Codipro manufactures its stainless steel lifting rings from 316L stainless steel. This makes them suitable for use in humid, corrosive, chemical and marine environments.

The OpenSupply stainless steel range includes different versions, allowing you to select a lifting ring according to the required freedom of movement, connection type and working load.

The range includes:

• lifting rings with single swivel;

• lifting rings with double swivel;

• lifting rings with a male thread;

• lifting nuts with a female thread;

• metric versions;

• UNC versions;

• stainless steel lifting rings for specific applications such as quick mounting and fall protection.

Stainless steel lifting rings with single swivel

SS.SEB for flexible lifting

The SS.SEB is a stainless steel lifting ring with single swivel. This version is suitable for applications where rotational movement is required, but double articulation is not necessary.

OpenSupply lists the SS.SEB with a maximum working load of 2.5 tonnes at SF 5:1 and a maximum bolt size of M24.

The single swivel provides greater flexibility than a fixed lifting point and makes the SS.SEB suitable for various professional lifting applications.

Stainless steel lifting rings with double swivel

SS.DSR for maximum freedom of movement

When a load needs to rotate or tilt during lifting, the SS.DSR provides additional freedom of movement.

The SS.DSR is a stainless steel double swivel lifting ring. According to Codipro, it is available with metric threads from M6 to M30 and UNC threads from 1/4" to 1". Depending on the version, the WLL ranges from 0.10 to 3.50 tonnes.

The double articulation allows the lifting ring to align more effectively with the direction of the load during lifting.

OpenSupply lists the standard SS.DSR with a maximum working load of 3 tonnes at SF 5:1 and a maximum bolt size of M30.

SS.DSS for heavier loads

For applications requiring a higher working load, the SS.DSS is available.

This stainless steel double swivel lifting ring is designed for heavier lifting applications. Codipro specifies metric sizes from M24 to M56, with WLLs from 2.70 to 8.00 tonnes. UNC versions are available from 1" to 2 1/2", with WLLs from 6,000 to 14,000 lbs.

OpenSupply lists the SS.DSS with a maximum working load of 8 tonnes at SF 4:1 and a maximum bolt size of M56.

This makes the SS.DSS a suitable solution when the capacity of a smaller stainless steel lifting ring is insufficient.

Stainless steel lifting nuts with female connection

Not every structure is suitable for a lifting ring with a protruding bolt. OpenSupply therefore also offers stainless steel lifting nuts with a female connection.

SS.FE.DSR

The SS.FE.DSR is a stainless steel double swivel lifting nut. It features a female thread and is available in metric and UNC versions.

Codipro specifies metric sizes from M8 to M22, with WLLs from 0.30 to 2.20 tonnes. UNC versions are available from 5/16" to 7/8", with WLLs from 600 to 5,100 lbs.

OpenSupply lists the metric SS.FE.DSR with a maximum working load of 2.2 tonnes at SF 5:1 and a maximum nut size of M22.

SS.FE.DSS

For heavier applications, the SS.FE.DSS is available. This is a stainless steel double swivel lifting nut with a female connection.

According to Codipro, the metric version ranges from M24 to M36, with WLLs from 2.70 to 5.00 tonnes. UNC versions are available from 1" to 1 1/2", with WLLs from 6,000 to 11,000 lbs.

OpenSupply lists the SS.FE.DSS with a maximum working load of 5 tonnes at SF 5:1 and a maximum nut size of M36.

Quick mounting with the SS.QL.DSR

For applications where fast installation is important, Codipro offers the SS.QL.DSR.

This stainless steel Quick Lift Ring features double articulation and, according to Codipro, can be anchored considerably faster than a conventional screw-on lifting ring. The system is mechanically operated and uses a spring mechanism.

The double articulation provides optimal alignment with the load. The ring can also rotate under load and is suitable for different lifting configurations.

An important advantage of the stainless steel version is its enhanced corrosion protection. This makes the SS.QL.DSR suitable for humid, chemical and marine environments, among others.

Stainless steel lifting rings with UNC thread

Not every machine or structure uses metric threads. The range therefore also includes stainless steel lifting rings with UNC threads.

The SS.DSR UNC is a stainless steel double swivel lifting ring. OpenSupply lists a maximum working load of 6,000 lbs / 2.7 tonnes at SF 5:1 and a maximum bolt size of UNC 1"-8.

Female UNC versions are also available, including the SS.FE.DSR UNC. OpenSupply lists a maximum working load of 5,000 lbs / 2.3 tonnes at SF 5:1 and a maximum nut size of UNC 7/8"-9.

This means a suitable stainless steel lifting solution is also available for structures with UNC threads.

316L stainless steel for demanding environments

An important characteristic of the Codipro stainless steel range is the use of 316L stainless steel.

This material is particularly suitable for environments where moisture and corrosion are important considerations. Codipro specifically mentions:

• humid environments;

• corrosive environments;

• chemical environments;

• marine environments.

The use of stainless steel helps support the service life of the lifting point when exposed to such conditions.

A stainless steel lifting ring is therefore particularly interesting when both the mechanical load and the environmental conditions play an important role in product selection.

Single or double swivel?

The choice between a lifting ring with single or double swivel depends on how the load needs to be lifted.

Single swivel

A model such as the SS.SEB is suitable when a single rotational movement is sufficient.

Double swivel

Models such as the SS.DSR and SS.DSS are suitable when the load requires greater freedom of movement during lifting.

The double articulation allows the ring to adapt more effectively to the direction of the load.

Metric or UNC thread?

The stainless steel range includes both metric and UNC versions.

Metric thread

The metric versions are suitable for structures with metric threads. Depending on the model, different sizes are available.

UNC thread

Specific versions are available for applications with UNC threads, such as the SS.DSR UNC and SS.FE.DSR UNC.

The correct version should always be selected based on the existing connection, required working load and operating environment.

Safety and technical quality

For professional lifting applications, it is essential that a lifting point is suitable for the load and the specific lifting configuration.

Codipro specifies safety factors of 4:1 and 5:1 for its stainless steel lifting rings, depending on the version. The products are designed for professional use and are provided with technical markings and documentation depending on the model.

The working load, thread size and safety factor vary between models. Always check the technical specifications of the selected version before using the product.

Which stainless steel lifting ring do you need?

The right choice depends on several factors.

How heavy is the load?

Select a version with a WLL (Working Load Limit) suitable for the intended lifting application.

Do you need single or double swivel?

For simple rotational movement, a SS.SEB may be suitable. When greater freedom of movement is required, the SS.DSR and SS.DSS are suitable options.

Do you need a female connection?

Choose an SS.FE.DSR or SS.FE.DSS, depending on the required working load and thread.

Are you working with UNC thread?

Several UNC versions are available within the range.

Is corrosion resistance important?

When the lifting point is used in a humid, chemical, corrosive or marine environment, a 316L stainless steel version is an interesting choice.
