A method for producing metal beams having a top-hat profile comprises the hot rolling of slabs (13), ingots (12), billets, preliminary profiles (14) or similar semifinished products in a rolling train. The rolling train comprises at least two roll stands. Using at least two shaping passes during a single rolling process in a number of rolling stations at hot-rolling temperature, preferably simple irregular pass design turns an entering cross section (10) of a one-part semifinished product into an exiting cross section having a top-hat profile (A), which corresponds geometrically more or less to the profile of the finished product.

A section mill (10) for the rolling of steel sections is disclosed. The section mill includes a universal mill stand (12) and an edger mill stand (14) for rolling a workpiece (18) in a plurality of back-and-forth passes into a steel section having a web and one or more flanges. The section mill further includes a cooling arrangement (16) for cooling the workpiece while it undergoes rolling during one or more of the passes. The cooling arrangement includes a cooling box (20) having a spray head (21) with spray openings (22) for spraying jets of pressurized cooling liquid against the workpiece. The cooling arrangement further includes an actuator (38, 34) configured to move the cooling box relative to the stand frame (58) of the universal mill stand and/or of the edger mill stand for adjusting a distance between the spray openings and the workpiece.

To suppress the occurrence of a defective shape such as a flange wave or the like by reverse rolling so as to improve the product dimension accuracy and stability of rolling. A production method for forming a steel sheet pile with flanges from a material to be rolled by caliber roll rolling, includes a step of performing reverse rolling on the material to be rolled by a same caliber, wherein: the step of performing reverse rolling includes a step of forming first flange parts across a neutral line and second and third flange parts arranged on both sides of the first flange parts; the caliber includes first flange facing portions for forming the first flange parts, second flange facing portions for forming the second flange parts, and third flange facing portions for forming the third flange parts; and an inclination angle of the first flange facing portion with respect to a horizontal plane is larger than inclination angles of the second and third flange facing portions.

A construction framing blocking component comprises a web, a first flange, a second flange, a first ear, a second ear, a third ear, and a fourth car. Each flange has a first edge attached to a web first edge and extends away from the web bottom surface. Each car extends from a flange end. The blocking component may be made by cold roll forming which bends a planar piece of steel into the web and two flanges and then remove a portion of the web on opposing sides to create the cars.
