Why is rust so common during sea transport?

• Long-term sea transport: High humidity and salt spray concentrations at sea can easily damage the protective film on metal surfaces.

• Large temperature fluctuations: Diurnal temperature swings during transport can cause condensation, which deposits on metal surfaces and can also cause localized corrosion.

• Dense stacking: When large quantities of metal products are stacked together, air circulation is poor, and if moisture accumulates, rust is more likely to form.

• Contact with acids, alkalis, or contaminants: Unsuitable packaging materials can release harmful substances, accelerating corrosion.

Therefore, in high humidity and long-distance transportation conditions, additional rust prevention is still necessary. Otherwise, rust on the metal surface not only affects the appearance, but may also affect customer perception of product quality and even increase subsequent handling costs.

How to prevent rust on stainless steel coils during long-term ocean transport?

Stainless steel coils can still rust during long ocean transport. High humidity and salt spray concentrations, coupled with large temperature fluctuations, can cause condensation in containers. These factors can gradually corrode the stainless steel surface, leading to the formation of rust spots. Once rust forms on the surface, it not only affects the appearance but also affects subsequent use and customer satisfaction.

Traditional rust prevention methods include applying antirust oil, waxing, or adding desiccant. However, these methods are either cumbersome to apply or clean, or have limited effectiveness. VCI antirust paper is truly suitable for large-scale export shipments.

VCI antirust paper contains VCI, which releases "rust-inhibiting molecules" in a sealed environment, acting like a protective shield around the metal coil. It not only prevents air and moisture from corroding the stainless steel but also keeps the coil surface clean and tidy. Upon arrival, the goods can be used directly after unpacking, eliminating the need for time-consuming cleaning of oil stains. This rust prevention method is truly convenient for long-distance ocean shipments.

How to Choose the Right VCI AntiRust Paper

CVCI's VCI antirust paper is a star product, refined through years of research and development and practical application. It's not only reliable in preventing rust, but also environmentally friendly and fully compliant with international RoHS and REACH standards. In other words, it's user-friendly, environmentally friendly, and safe to use.

CVCI has its own R&D laboratory, equipped with a professional salt spray tester, constant temperature and humidity equipment, and various test conditions that simulate transportation environments. Here, we can pre-test products to see how they perform in various high-humidity and high-salt spray environments.

In addition to our national-level R&D laboratory, we also have our own factory, where our production line adheres to a strict quality management system. Every batch of VCI antirust paper is tested before shipment. This eliminates the worry of batch-to-batch performance. We strive for the peace of mind of stable, long-term cooperation.

We understand our customers' concerns.

During long-term export shipping, customers are most concerned about a few key issues:

• Can it truly prevent rust?

• Will it leave residue on the product surface?

• Is the cost manageable?

• Is the packaging easy to use?

We've taken all of these into account. Our VCI antirust paper is extremely easy to use, requiring no additional cleaning, saving labor. It's also highly efficient for packaging, making it particularly suitable for bulk exports. Even when shipped to hot and humid climates, it maintains long-term, stable protection.

Customer Feedback

A customer originally exported stainless steel coils using the traditional method of applying oil and adding desiccant. However, upon arrival at the destination port, small rust spots still appeared on some of the coils, increasing cleaning costs and rendering the products unusable. Later, they tried our VCI antirust paper, which tightly wrapped the coils, and the entire shipping process was trouble-free. Upon arrival at the port, they unwrapped the coils, finding them spotless, and delivered them directly to the buyer. The feedback was incredibly positive. We were surprised to see how much trouble a change in packaging material saved. We are truly pleased to hear this positive customer feedback.
