Carl Froh produces longitudinally welded precision steel tubes according to DIN EN 10305-3 and dimensionally rolled square and rectangular tubes according to DIN EN 10305-5. These are characterised by close tolerances and a consistent surface quality.
In addition to starting material in standard grades, such as hot-rolled and cold-rolled strip, we also process large quantities of sendzimir galvanised strip.
Our precision steel tubes are manufactured in the delivery states +CR1 and +CR2 from various materials E155, E195, E220, E235, E355, E420, E460, E500, E700 and other high-strength grades on request.
Our product range includes round, square, rectangular and flat oval tubes, starting from a round tube outer diameter of 8 mm to 88.9 mm. The wall thickness is possible from 0.5 - 4.0 mm.
Special cross-sections according to customer requirements are also possible. The inner weld seam can be scraped accordingly and the position location can be defined.
