Strut channel assemblies for industrial facilities and methods of assembling same

A strut channel assembly for constructing a heavy-duty trapeze system of an industrial facility, the strut channel assembly comprising:

• an elongated strut channel formed as one single piece, the strut channel comprising:
• a bottom wall;
• and
• a first side wall and a second side wall extending from edges of the bottom wall along a longitudinal direction of the bottom wall, the first side wall and the second side wall facing one another, the first side wall forming a first longitudinal rail, and the second side wall forming a second longitudinal rail facing the first longitudinal rail, wherein:
• the first longitudinal rail and the second longitudinal rail each comprise a first elongated rail surface that intersects a second elongated rail surface, and
• the respective first elongated rail surface is perpendicular to the respective to the second elongated rail surface;
• and
• a nut positioned inside the strut channel and coupled with the strut channel along the first longitudinal rail and the second longitudinal rail.
