The key principles for storing and transporting SUS630 laminated steel plates are “prevent corrosion, deformation, and damage.” Considering the characteristics of the surface passive film and mechanical properties, the specific requirements are as follows:
1. Storage Environment
* Prefer indoor, dry, and ventilated warehouses, maintaining humidity below 60%. Avoid exposure to rain, direct sunlight, or prolonged damp conditions.
* Do not store corrosive materials such as acids, alkalis, salts, or sulfur-containing substances in the warehouse. Keep a distance of at least 1 meter from dissimilar metals such as carbon steel or cast iron to prevent contamination and corrosion.
* The warehouse floor should be level and dry, with wooden planks, rubber mats, or moisture-proof pallets underneath to prevent direct contact with ground moisture. The bottom of the plates should be at least 10 cm above the ground.

2. Storage and Stacking Guidelines
* Stack plates according to thickness and specification. Avoid mixing different sizes, and limit stacking height to 1.5 m (thin plates ≤1 m) to prevent deformation of the bottom plates.
* Place moisture-proof and anti-slip pads (e.g., PE film, non-woven fabric) between plates to prevent scratching and isolate from moisture.
* For long-term storage (over 3 months), fully wrap the plates in moisture-proof film and regularly check warehouse humidity. Ventilate and dehumidify if condensation occurs.

3. Pre-Transportation Preparation
* Inspect the protective film on the plate surface; repair or reapply damaged areas. Add rubber corner protectors to edges to prevent impact damage.
* Secure plates with straps or steel bands, adding cushioning (e.g., rubber strips, foam pads) to avoid indentations from strap pressure.
* Check the transportation route; for routes through coastal or humid areas, add rainproof covers and moisture-proof film for double protection.

4. Transportation Requirements
* Use enclosed trucks or containers to avoid rain, direct sunlight, or contact with dust and corrosive substances.
* Line the vehicle with anti-slip rubber mats; place plates flat and secure them to prevent sliding, collision, deformation, or surface scratches.
* Do not transport with carbon steel, cement, fertilizers, or other materials that may cause contamination or corrosion. Ensure the vehicle is clean with no residual corrosive substances.

5. Loading and Unloading Practices
* Use forklifts or cranes with rubber-covered forks or lifting devices to avoid direct contact with sharp parts.
* Handle plates gently; do not drag or throw. For single or small batches, wear clean cotton gloves to avoid scratching the surface.
* When handling multiple plates simultaneously, distribute the load evenly to prevent bending or deformation from point loads.
