Product Description

Q345B carbon pipe mounting bracket supplier new galvanized ms steel square tube



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





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
