Orthotropic Deck Thick Steel Plates for Steel Bridge Decks

Our orthotropic deck thick steel plates (grades S355N, S460N) offer high fatigue resistance for highway and railway bridge decks. Fine grain structure and low sulfur content improve weld toe durability. These thick steel plates handle heavy wheel loads and dynamic vibrations. Thickness 8–50mm, widths up to 3500mm. Tight crown and camber tolerances. Easy to weld with low hydrogen. Reduce deck cracking and maintenance. Build longer-span bridges with fatigue-optimized thick steel plates.
