Many overseas buyers encounter scratched zinc coating, white rust and surface abrasion after ocean shipment. Most problems are not caused by production quality, but by unprofessional packaging and improper container loading. Long-distance sea transportation features continuous vibration, heavy stacking pressure, high humidity and salt spray, which requires strict export-grade packaging solutions.
Standard export guardrail packaging focuses on three core protections: anti-friction, anti-extrusion and moisture-proof.
First, surface isolation protection. Buffer isolation materials are placed between each guardrail beam to avoid friction scratches and zinc layer peeling during long-term sea vibration. Corner protectors prevent edge deformation and damage during loading and unloading.
Second, overall stack reinforcement. All guardrail stacks are tightly fixed with high-strength steel belts to prevent displacement, scattering and extrusion deformation inside the container. Reinforced anti-bending treatment ensures flat beam surface and standard radian after arrival.
Third, ocean moisture-proof treatment. Full waterproof and moisture-proof wrapping isolates humid air and salt spray, effectively preventing oxidation and white rust. All wooden pallets are heat-treated and fumigated to meet international shipping customs requirements.
We implement strict ocean shipping packaging standards for all export orders. Full-process protection ensures zero damage during transportation and perfect on-site installation for overseas projects.
