  • what’s the difference between Pre galvanized and Hot

    It is the most popular galvanizing method and is widely used in the construction industry. Pre galvanizing pipe,also known as mill galvanized pipe, hot dip mill galvanized or continuous hot dip galvanized.Pre galvanized steel pipe refers to pipe which was galvanized while in sheet format, thus prior to further manufacturing. After the sheet is sent through the mill to be galvanized it is cut to size

  • Difference between GI and MS Permanent Steel

    The corrosive properties of the steel pipeline mean that it must be properly sealed through painting or a process often used on pipelines that involves wrapping the pipe with a corrosive resistant material.Often in very cold climates, a warming type of insulating material is wrapped around the pipeline.

  • What is Galvanized Steel Pipe? Sunny Steel

    To create galvanized steel pipe, steel materials are placed into a molten bath of zinc. This process is also called hot dip galvanization. The two metals are chemically bound to one another in this process, and will therefore never separate, resulting in a more resistant and longer lasting version of steel.
