How to Keep your Metal Parts Rust-free when Shipping Containers Overseas

Industries dealing with shipment and transportation through seas understand the importance of protecting the shipment from any harm. Physical harm aside, there is another important matter of concern during shipment. When the shipment is of metal-based materials, there is a high risk of corrosion due to harsh weather in the seas. The ship containers have to bear the complete brunt of the extremely humid surroundings, salt-water sprays, mist and dews of the night and day changes, and sudden rains and storms. Therefore, ensuring better corrosion protection is a necessity.

Reason Behind Shipment Corrosion and its Effects

Manufacturers, suppliers, and transportation companies of metal-based products need to understand what causes corrosion, the reasons, and its effects.

1. Loose packaging

When the metal products are ready to be shipped, they are sometimes not packed tightly in their respective covers. Due to this, it is easy for external elements to penetrate and trigger the rusting process.

2. Lack of RPO layering

These times demand some rust preventive oils layering on metal products as a barrier from corrosion. When this important step is skipped by manufacturers and suppliers, it can cause additional loss from corrosion in transit.

3. Insufficient Desiccants

Desiccants are extensively used where moisture is a hurdle. Therefore, missing out on a good number of desiccants can be a way to welcome moisture particles in a place like a sea. Hence, corrosion is inevitable.

4. Improper Container Hold

The shipment is usually kept in cargo holds or containers on the ship. It is important to clean and maintain those containers before initiating metal objects transfer. A clean and properly closed-off container ensures the least possibility of corrosion.

5. Salt-Water Showers

It is natural to experience salt-water showers on the ship when you are in the middle of the sea. When complete physical barriers with rust preventive oils, VCI barriers, and VCI desiccants are used, corrosion is averted.

6. Temperature Fluctuations

It is usual for the temperature to have a sudden drop in the middle of the seas after sunset. This can lead to morning mist and dew as well. This dew leads to container rain as well as temperature drops. All of these contribute greatly towards corrosion if metal objects are exposed.

7. Humidity

The boon of all reasons, humidity is a combination of air contaminants, water, and oxygen all of which are responsible for corrosion. Hence, at sea, you can experience all these extreme levels of humidity.

How to Protect Metal Parts during Shipment?

While we have perused all the possible reasons during shipment that can lead to metal corrosion, we need a solution to this problem. Zavenir Daubert has numerous products that can contribute to metal object corrosion protection.

1. Rust preventive oils

Rust preventive oils are certain treated oils that have infused chemicals to form a protective molecular level layer over the metal surface. This layer is a physical barrier against corrosion and lasts longer.

2. Desiccants and Emitters

Daubert VCI Desiccants and Emitters absorb moisture and emit VCI molecules to form a barrier layer on the metal surface to protect the metal from corrosion.

3. VCI polybags, papers, sheets

These are packaging materials that can be used for wrapping up metal objects of all sizes. After a certain duration, the VCI molecules settle on the metal surface to build a molecular barrier against corrosion.

4. Combination of two or more above

When the combination of the above solutions is used, the life of the metal objects increases even more. The better the protection, the better the results. Therefore, keeping desiccants as a necessary protection, and adding rust preventive oils can help provide double protection. Add to it the packaging material being VCI wrappings, and it keeps the objects intact.

Therefore, to keep the metal parts rust-free, there are certain barriers and protections available. With Zavenir Daubert as your corrosion expert and protective products, you can find the best consultation advice for your products to make them corrosion-resistant during shipment.
