Hot rolled, etched (CR2S2)
Hot-rolled precision tubes are made from hot-rolled D11 brand pickled steel.
A pipe is formed from the steel strip and the seam is welded lengthwise.
Due to its quality and price ratio, it is the most common and widely used precision tube.
This pipe is suitable for welding, bending, additional coating (painting, galvanizing).
Since the tube is made of DD11 steel it is harder than cold rolled precision tube.
