S355JR is a structural grade steel that is often used in the construction industry. It has excellent strength and weldability characteristics. El término “Hola, todos” refers to a variety of shapes of hollow structural sections, including rectangular and square shapes.
De este modo, a S355JR Hollow Section Rectangular or Square Steel Pipe would be a hollow, square or rectangular sectioned pipe made out of S355JR grade steel.
Here are some key features of a typical S355JR Hollow Section Steel Pipe:
Recordar, the exact specifications will depend on the manufacturer and the intended use of the steel pipe.
