Detail Information
Standard: API 5L-2009 ISO 3183-2007 DIN 30670 ( Coating)
Steel Grades: A53 gr. B
Size:33.5х3.2 mm
Coating Thickness: 2mm- 5mm
Manufacturing Process : ERW
Application:Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O₂) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO₂) to form zinc carbonate (ZnCO₃), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle. It can be identified by the crystallization patterning on the surface (often called a "spangle").
Packing: External Black Painting ,Both Side With End Caps, In Bundles by Steel Strips,Covered by Waterproof.
