ItemDescription
High Lateral Pressure ResistanceTrapezoidal section has higher moment of inertia, resists heavy cargo impact and side pressure
Thick Plate Anti-Crack FormingLarge bending angle + large R radius, avoid cracking for thick plate cold bending
High Integral StrengthOne-piece cold bending, no splicing weld, good stability and deformation resistance
Multiple Anti-Corrosion OptionsShot blasting + painting, hot-dip galvanized, aluzinc available
Processing Remarks1. Match bending R radius according to plate thickness
2. Low hydrogen welding electrode for high strength steel, preheat for thick plate
3. Anti-corrosion treatment required for marine salt fog environment
