Q1: What specialized handling prevents damage to aluminum coils during shipping?
Steel mandrels support coil eyes to prevent crushing. Edge protectors shield against forklift impacts. VCI (Vapor Corrosion Inhibitor) paper interleaving controls humidity. Container load plans limit stacking to two tiers. GPS-tracked tilt monitors alert if inclinations exceed 5°.
Q2: How do you calculate maximum stacking height for extruded profiles?
ISTA 3E simulations determine pallet compression limits. Honeycomb stacking patterns optimize container space utilization. Load-securing straps tensioned to 50 kg/f avoid deformation. Anti-slip sheets prevent shifting during transit. Non-symmetric sections require custom crating solutions.
Q3: Why is container ventilation critical for aluminum sea freight?
Temperature swings cause condensation ("container rain"). Desiccant bags absorb up to 300% humidity by weight. Forced-air ventilation maintains <40% relative humidity. Wool insulation liners mitigate solar heat gain. IoT sensors transmit real-time humidity/temperature alerts.
Q4: What RFID technologies enable efficient aluminum inventory management?
UHF RFID tags withstand metal interference via ABS plastic spacers. Yard management systems auto-update stock locations. Handheld readers scan 200+ items/minute with 99.9% accuracy. Cloud platforms integrate with ERP systems like SAP MM. Battery-free tags use RF energy harvesting.
Q5: How do you prevent galvanic corrosion in multi-metal shipments?
Dielectric barriers (plastic film) isolate aluminum from steel/copper. VCI-emitting foam sheets neutralize corrosive electrolytes. Desiccants maintain dew points below cargo temperature. Air-tight sea containers minimize oxygen exposure. Conductivity tests verify isolation integrity pre-shipment.
