Corten Steel Water Feature

corten steel water feature or corten steel water trough shape like corten steel fountain with corten metal sculpture wall art & corrosion resistant steel. metal trough planter by rust colour with water though looks great. Specification: Materials: Q235NH/S235JOW/S235J2W 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 Pre weathered steel trough Chemical Composition Grade   Chemical Component /% C Si Mn P S Cu Cr Ni Q235NH ≤0.13 0.1-0.5 0.2-0.6 ≤0.030 ≤0.030 0.25-0.55 0.4-0.8 ≤0.65 S235J0W ≤0.13 ≤0.40 0.2-0.6 ≤0.035 ≤0.03 0.25-0.55 0.40-0.80   S235J2W ≤0.13 ≤0.40 0.20-0.6 ≤0.035 ≤0.035 0.25-0.55     Pre weathered steel trough Mechanical Properties Materials Mechanical properties   Yield point(Mpa) Tensile strength(Mpa) Elongation(%) Q235NH ≥235 360-510 ≥25 S235J0W ≥235 360-510 ≥25 S235J2W ≥235 360-510 ≥25 Corrosion resistance steel water channel Construction steps: The corten steel do Shot blasting treatment by shot blasting machine. The corten steel should be cutted and bentted by CNC machine according to the design drawing. Welding the corten steel materials as the drawing. Cleaning the surface again. Then do rusting treatment. When the weathing steel surface color becomes which u want, then do rust curing treatment.  Installing the corten steel at the park by the way of welding and Lay the keel behind the back.
