Corten Steel Dealers in Girgaon, Mumbai

The unique look and naturally oxidizing finish of Corten Steel Tubing make it especially desirable for many architectural projects. The atmospheric corrosion resistance of weather – resistant steel piping is based on the chemical composition of the steel. Under the influence of weather conditions a dense protective patina layer composed of corrosion products is formed on the surface of the Corten Steel Panels. To use the benefits of the higher atmospheric corrosion resistance of weather – resistant steel tubing in comparison to unalloyed steel, it is necessary that design and execution of structures as well as the performance of maintenance works allow an impeded formation and regeneration of the protective rust layer.

Its Influence Varies and Depends Mainly Upon General Weather Condition (e.g. Continental) Macroclimate (e.g. Industrial, Urban, Maritime or Countryside Climate) and the Orientation of the Structure Components (e.g. Exposed to or Shaded from the Weather, Vertical or Horizontal Position). the Amount of Aggressive Agents in the Air Has to Be Taken Into Account . in General the Covering Layer Offers Protection Against Atmospheric Corrosion in Industrial, Urban and Countryside Climate. when Utilising this Steel in Unprotected Condition It is Up to the Designer to Take Into Account the Expected Loss of Thickness Due to Corrosion and as Far as Necessary, Compensate for It By Increasing the Thickness of the Material. in Cases of Particular Air Pollution By Aggressive Agents Conventional Surface Protection is Recommended. Coating is Absolutely Necessary in Cases of Contact with Water for Long Periods, When Permanently Exposed to Moisture, or if It is to Be Used in the Vicinity of the Sea. the Susceptibility of Paint Coats to Undercreepage By Rust is Less in the Case of Weathering Steel Than in the Case of Comparable Non-weathering Steel. applications the Steel is Used for Various Types of Welded, Bolted and Riveted Constructions E.g. Steel Frame Structures, Bridges, Tanks and Containers, Exhaust Systems, Vehicles and Equipment Constructions. basic Guidles for the Use of this Steel in the Unprotected Condition are Described in En 10025-5 and Dast Rule 007. the Entire Application Technology is of Fundamental Importance for the Performance of the Products Made from this Steel. It Must Be Taken Into Account that Not Only General Climate Conditions But also Specific Unfavourable Local Climate Conditions in the Broadcast Sense as Well as Details of a Construction May Affect the Corrosion Behaviour of Unprotected Weathering Steel. the Dependency On These Facts Makes It Understandable that No Warranty Can Be Given. It is Recommended to Control the Corrosion Progress of Protected Parts Out of Weathering Steel Exposed to the Influence of Weather in Reasonable Time Intervals. a Minimum Thickness of 5mm is Recommended When Exposed to the Weather in the Unprotected Condition. to Use the Benefits of the Higher Atmospheric Corrosion Resistance of Cor-ten in Comparison to Unalloyed Steel It is Necessary that Design and Execution of Structures as Well as the Performance of Maintenance Works Allow An Impeded Formation and Regeneration of the Protective Rust Layer. the Methods Must Meet the Latest Requirements of Technical Progress and Must Be Suited for the Proposed Application.
