Square tubes made of stainless steel are long components in which solids, liquids or gases can be carried depending on the diameter and structure. In this function, stainless steel has proven to be successful for various reasons. In the food industry it is a crucial advantage that the transport material is hygienic and tasteless. A high degree of resistance to corrosion is also important wherever a high degree of humidity exists or systems are used to transport liquids. Stainless steel square tubes are also characterized by their shape. They can be rectangular or square – this is how the pipes save space.
