Packaging
- Material Protection: Gate seals are typically packaged in sturdy materials such as wooden crates or plastic boxes to ensure they are not damaged during transportation.
- Water and Moisture Resistance: As the seal material is sensitive to moisture, special attention must be paid to waterproofing and moisture-proofing during packaging, which may require the use of waterproof film or sealed bags.
- Clear Identification: Each packaging box should have clear warning labels such as "Fragile," "Keep Dry," "This Side Up," as well as product name, model, quantity, and other information.
- Internal Securing: To prevent rolling or movement during transportation, the seals should be secured internally with foam or other cushioning materials.
Transportation
- Gentle Handling: During loading and unloading, appropriate lifting equipment should be used, and operations should be gentle to avoid impact or compression damage to the seals.
- Avoid Extreme Weather: Transportation should be avoided in extreme weather conditions such as high temperatures, extreme cold, or heavy rain to prevent affecting the performance of the seals.
- Safe Storage: En route, seals should be stored in a dry, well-ventilated environment, away from direct sunlight and high temperatures.
- Compliance with Regulations: All relevant transportation laws and safety standards should be followed during transportation to ensure the safety of personnel and goods.
