Common Pitfalls in Coil Transportation: Have You Fallen Victim?

/in /by

As a vital product in the steel industry, steel coils are widely used in construction, automotive, machinery, home appliances, and other sectors. Due to their large size, significant weight, and stringent surface quality requirements, steel coils are highly susceptible to damage during long-distance transportation. Inadequate protective measures during shipping not only result in direct economic losses but also compromise customer experience and corporate reputation.

1.Common Causes of Damage During Coil Transportation

A.Moisture Exposure and Oxidation/Rusting

Causes: Rain exposure during transit, salt spray in maritime environments, or excessive humidity in storage facilities.

Hazards: Surface rust spots that compromise aesthetics and may degrade mechanical properties.

B.External Mechanical Damage

Causes: Direct contact between coils and steel cables/forks during hoisting or forklift handling; collisions with other cargo due to road vibrations.

Hazards: Surface scratches and indentations complicate subsequent processing.

C.Edge Damage

Causes: Improper packaging or inadequate securing, causing edge flanges to endure concentrated stress or friction during transit.

Hazards: Cracked edges and burrs impair cutting precision and finished product accuracy.

D.Coil Deformation

Causes: Improper stacking or insufficient pallet strength leading to tilting and distortion of coils.

Hazards: Coils become unusable on machinery or may be classified as scrap.

E.Insecure or Loose Bundling

Causes: Insufficient steel strapping quantity or tension, or vibration-induced loosening during long-distance transport.

Hazards: Coils shift within trucks or containers, significantly increasing collision risks.

F.Missing or Incorrect Labels

Causes: Label detachment or illegible markings during transit.

Hazards: Receiving parties struggle to verify specifications, complicating warehousing and sorting.

2.Solutions

A.Moisture and Rust Prevention

Seal steel coils with rust-proof paper or vacuum PE film;

Place desiccants or dehumidifiers in containers during shipping;

Install rain covers during rainy seasons to prevent direct exposure.

B.Reinforced Outer Protection

Apply galvanized steel sheeting or composite protective film to coil exteriors;

Install metal end caps on coil ends to resist impact and friction;

Use rubber pads or soft buffers on transport vehicles to prevent direct contact with hard surfaces.

C.Edge Protection

Wrap edges with plastic corner protectors or cardboard edge guards;

Ensure strapping bands do not directly damage coil edges.

D.Proper Stacking and Securing

Use sturdy pallets (wooden or steel) to ensure stable load-bearing;

Secure within containers using wedges or straps to prevent shifting;

Stack coils of different specifications separately, avoiding mixing large and small coils.

E.Standardized Strapping Method

Apply at least 4-6 steel straps per coil, combining horizontal and vertical strapping;

Ensure adequate tension to prevent loosening during transit;

Add protective padding over steel straps to avoid surface damage.

F.Label Management

Use waterproof labels, affixing one to the coil exterior and one to the inner packaging layer;

Label content must include: product model, weight, production batch, and shipping direction.

Damage during coil transportation is not inevitable. Implementing professional measures in packaging structure, securing methods, and moisture prevention can significantly reduce risks.
