Best Practices for Anti-Rust Packaging of Steel Products for Sea Shipment

Protecting steel products from corrosion during sea shipment is a critical concern for exporters and importers. The combination of salt-laden air and prolonged humidity during transit can quickly damage unprotected steel. Implementing robust anti-rust packaging protocols is essential to ensure goods arrive in pristine condition.

The foundation of effective protection is a clean, dry surface. Steel must be thoroughly cleaned of any moisture, dirt, or contaminants before packaging begins. The core of the defense system involves specialized materials:

VCI (Volatile Corrosion Inhibitor) Packaging: VCI paper or film is a cornerstone of modern anti-rust packaging. It slowly releases a protective vapor that forms an invisible shield on the metal surface, neutralizing the corrosive elements in the air. Coils and sheets are often wrapped directly in VCI paper.

Protective Coatings and Oils: A thin, uniform layer of anti-rust oil is frequently applied. For longer journeys or harsher conditions, a more durable desiccant or special coating may be used to provide extended protection.

The physical packaging must also form a barrier against the elements. The standard practice involves:

Wrapping the steel in VCI paper.

Using waterproof plastic sheet or laminated woven fabric as an outer layer to prevent direct water ingress.

Securing the package with steel or plastic straps on wooden skids or pallets to prevent movement and allow for safe handling.

This multi-layered approach—combining chemical inhibition (VCI), physical barriers (waterproof sheets), and proper structural support—creates a comprehensive defense system.

At Ruixiang Steel, we treat packaging with the same importance as production quality. Our standardized anti-rust packaging procedures are designed to withstand the rigors of long-distance sea freight, guaranteeing that your steel products are delivered corrosion-free and ready for use.
