The container door edge member is a critical structural component designed to reinforce container door frames, ensure secure sealing, and withstand repeated operational stresses during opening/closing cycles. Engineered to maintain door alignment, prevent deformation, and enhance weather resistance, it plays a pivotal role in protecting cargo from environmental damage and ensuring reliable performance in intermodal logistics.

Base Material: Constructed from high-strength low-alloy steel (Q345B, yield strength ≥ 345MPa) for optimal rigidity and impact resistance, with a galvanized finish (275g/m² zinc coating, ISO 1461) to combat corrosion.​
Profile: U-shaped or L-shaped extruded section (height: 50–80mm, wall thickness: 4–6mm) designed to fit seamlessly with container door panels and gaskets. Features pre-drilled mounting holes (M8–M12) at 150mm intervals for uniform load distribution.​
Welded Reinforcements: Integral stiffening ribs (3mm thickness) at hinge and lock rod attachment points, tested to withstand 1,000N·m of bending moment without permanent deformation.
