Storage, Transport and Inventory Management of CCS Grade B Shipbuilding Steel Plates

1. Storage Environment Requirements

1.1 Storage Location

CCS B steel plates should be stored in a dry, well-ventilated indoor warehouse, avoiding prolonged exposure to outdoor rain and salt spray.

1.2 Stacking Requirements

The stacking height must not exceed 1.5 metres. Spacer pads should be placed between steel plates to prevent surface scratches and deformation caused by compression.

1.3 Humidity Control

The relative humidity in the warehouse should be maintained below 60%. During damp seasons, desiccants should be placed to reduce surface condensation.

2. Transport Management Guidelines

2.1 Transport Vehicles

It is recommended to use enclosed transport vehicles to prevent exposure to rain and sea winds during transit.

2.2 Securing Methods

Steel plates should be securely fastened using steel straps to prevent slipping, impact and deformation.

2.3 Protection for Overseas Transport

For overseas transport, an additional layer of anti-corrosion protective film should be applied to isolate the steel plates from seawater vapour.

3. Inventory Management Strategy

3.1 Batch Management

Steel plates should be stacked and categorised by production batch and specification to ensure good traceability.

3.2 Turnover Cycle

The inventory turnover cycle should be kept within 90 days.

3.3 Long-Term Storage Maintenance

For steel plates stored for extended periods, regular rust removal and oil-sealing protection treatments should be carried out.

3.4 Pre-Delivery Inspection

Prior to delivery, the surface cleanliness of the steel plates should be re-inspected to ensure there are no severe layers of rust, so as not to affect subsequent welding and anti-corrosion work.
