Corten metal structure basis on the good mechanical properties, formability, weldability and low temperature toughness, but also has good corrosion resistance. So weather resistance structural steel has a good market prospects and market competitiveness. Widly used at Bridges, tanks and containers, exhaust systems, rail and road vehicles, windshields on chimneys, power station precipitators, rainscreen cladding, garden edging, firepits and art sculptures. 


Specification:
  • Materials: Corten/A588/A709
  • Thickness: 6-40mm
  • Width: 10-4200mm
  • Length: 10-12000mm
  • Special weld rod for weathering steel: che556nicrcu
  • Pretreatment of resistant steel surface: Shot blasting, Rusting treatment, rust curing treatment
