Steel Plates for Extended Paint Life EXPAL™

Contributing to life cycle cost reduction of steel structures under corrosion environments.

EXPAL™ extends the “paint life” of steel structures used as infrastructure in coastal areas by more than 2.4 times of the plain carbon steel. This substantially reduces the Life Cycle Cost (LCC) of steel structures used under severe corrosion environment.


  • Excellent durability against severe environment with high concentrations of airborne salt including marine environment, coastal zones and regions where deicing salt is used on roads.
  • Conforms to JIS G 3106 (SM material, Rolled steels for welded structure)
  • Low carbon equivalent (Ceq) and low weld crack sensitivity composition (PCM), and excellent in weldability and welded joint performance.
