What is black square&rectangular steel pipe?
Welding pipes is one of the simplest and most durable ways to join piping together and steel pipes can simply be welded together with MIG (metal inert gas), TIG (tungsten inert gas or SMAW (stick metal arc) welding. Before welding two pipes together, avoid any gaps between the two pipes.While welding, take measures to ensure the continual alignment of the two pipes.
What is pre galvanized square&rectangular steel pipe?
The pre-galvanized welded steel piperefers to welded tube which undergo degreasing,rush removal,phosphorization,zand drying processes before galvanization. The treatments before galvanization allow the product to be conveniently plated with a zinc coating,and also ensure uniform coating thickness,strong coating adhesion,and improved corrosion resistance
What is hot dipped galvanized square&rectangular steel pipe?
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel.
