A method of manufacturing a clamping strap configured to hold and support a hanging object against a structure , which is to carry the hanging object, said method comprising providing an extruded elongated aluminium profile having an initial material thickness (T 0 ) and an initial cross-sectional area (A 0 ), said profile having a longitudinal direction, which coincides with the extrusion direction of the profile; forming the profile in a bending step into a shape comprising a first end attachment portion , a second end attachment portion , and an intermediate portion located between said first and second end attachment portions (1a; 1b) in a longitudinal direction of the profile , said intermediate portion being configured to at least partially encircle the hanging object when mounted to the structure ; and characterized in that the method includes forming said profile by means of locally thinning the profile in a longitudinal direction of the profile , in a thinning operation to obtain one or more thinned portions having a lower material thickness than the initial material thickness (T 0 ); or locally axially compressing the profile in an axial compression step to obtain one of more axially compressed portions having a higher material thickness than the initial material thickness (T 0 ) and/or greater cross sectional area than the initial cross-sectional area (A 0 ); or by a combination of said thinning operation and said axial compression step . said method comprising providing an extruded elongated aluminium profile having an initial material thickness (T 0 ) and an initial cross-sectional area (A 0 ), said profile having a longitudinal direction, which coincides with the extrusion direction of the profile; forming the profile in a bending step into a shape comprising a first end attachment portion , a second end attachment portion , and an intermediate portion located between said first and second end attachment portions (1a; 1b) in a longitudinal direction of the profile , said intermediate portion being configured to at least partially encircle the hanging object when mounted to the structure ; and characterized in that the method includes forming said profile by means of locally thinning the profile in a longitudinal direction of the profile , in a thinning operation to obtain one or more thinned portions having a lower material thickness than the initial material thickness (T 0 ); or locally axially compressing the profile in an axial compression step to obtain one of more axially compressed portions having a higher material thickness than the initial material thickness (T 0 ) and/or greater cross sectional area than the initial cross-sectional area (A 0 ); or by a combination of said thinning operation and said axial compression step . locally thinning the profile in a longitudinal direction of the profile , in a thinning operation to obtain one or more thinned portions having a lower material thickness than the initial material thickness (T 0 ); or locally axially compressing the profile in an axial compression step to obtain one of more axially compressed portions having a higher material thickness than the initial material thickness (T 0 ) and/or greater cross sectional area than the initial cross-sectional area (A 0 ); or by a combination of said thinning operation and said axial compression step . <EOS>
