Dear Sir or Madam I am contacting you again regarding an order for steel profiles for the purpose of carrying out a test for the Chair of conceptual Design and Construction - Solid Construction at the Technical University of Berlin. For this we need curved steel components which we want to install on a deflection saddle. I would therefore ask you to let us know if you could provide a quotation for the curved U-profiles. The tolerances must be specified in the quotation. Details; The given radius is to be divided into 4 installation parts with the same dimension and angle. Details of the identical profiles are shown in a sketch and can be found in the appendix; Here we need 4 segments curved over the strong axis, each with an arc angle of 45° and a radian of length 1178.1 mm. The bending radius 1500 mm should be measured to the inside of the flange. manufactured with the utmost care and elaborately straightened. Particular attention must be paid to the radius and flatness of the profile. We then want to fasten the profiles with screws on the flange side to a curved steel construction of the deflection saddle. The link below shows roughly what the deflection saddle looks like. https://www.tu.berlin/ek-massivbau/services/umlenksattel The deflection saddle is a semicircle with a radius of 1500 mm. This requires curved components of the UPE 180 profile to be installed along this semicircle. Therefore, I would like to emphasize that the 4 profiles must be manufactured almost exactly to the given dimension. I look forward to your positive response and will be happy to answer any further questions you may have.
