A universal mount platform for office and industrial modular workstations including embodiments of an N-side slot mount matrix. The N-side slot mount matrix also includes an N number of outer rails arranged in a N-sided polygon, where N is an integer, each of the outer rails having two outer rail ends, each of the two outer rail ends coupled to one of the outer rail ends of another one of the outer rails. The N-side slot mount matrix has an N number of inner rails, each of the inner rails having a first end coupled to one of the outer rails and a second fend coupled to another one of the inner rails. The N-side slot mount matrix has an N number of mount slots, each between one of the inner rails and an adjacent one of the outer rails.

A strut channel support system including a first brace, a second brace, and a fastening mechanism connects at least two channel struts in a multi-orientable fashion. The first brace and the second brace both possess a U-shaped channel, a base, a fastener-engagement point, and a strut-engagement point. The base is terminally connected to the U-shaped channel, the fastener-engagement point is centrally integrated into the base, and the strut-attachment feature is integrated into the U-shaped channel. This permits the base to retain the rear portion of a strut channel. The U-shaped channel perimetrically braces the lateral sides of the strut channel. The first brace and the second brace attach to each other via the fastener-engagement point. The fastener-engagement point of the first brace and the fastener-engagement point of the second brace are mechanically coupled to each other. This enables a user to adjust the orientation between at least two strut channels.

A Three-Dimensional Positioning and Holding Modular System for office and industrial work stations including embodiments of multi-rail beams and rail-arm-leg modules. The embodiments have tubes, bars, or channels arranged and connected in ways that provide improved ability to transmit torque along a long axis of the multi-rail beam while providing improved resistance to twisting under the forces of the torque.

An H-section steel has a predetermined chemical composition, in which a Mg-containing oxide having an equivalent circle diameter of 0.005 m to 0.5 m is contained at a total number density of 100 pieces/mm.sup.2 to 5000 pieces/mm.sup.2, a thickness of a flange is 100 mm to 150 mm, at a strength evaluation portion which is at a position from a surface of the flange in a length direction and at a position from the surface in a thickness direction, a fraction of bainite in a steel structure is 80% or more, and the average prior austenite grain size is 70 m or more, and at a toughness evaluation portion which is at a position from the surface of the flange in the length direction and at a position from the surface of the flange in the thickness direction, the average prior austenite grain size in a steel structure is 200 m or less.

An extrusion structure including a central body extending along a longitudinal axis; a first arm body secured to the central body and extending along the longitudinal axis; a second arm body secured to the central body and extending along the longitudinal axis; a first head body secured to the first arm body and extending along the longitudinal axis; and a second head body secured to the second arm body along the longitudinal axis; and wherein the first and second head bodies projecting one towards the other and being spaced apart by a gap, the first head body having a first internal face facing the central body, the second head body having a second internal face facing the central body, and the first and second internal faces being either straight and coplanar or inwardly inclined towards the central body.

A panelized building system utilizing structural framing combined with integrated insulation is disclosed. The system may include a roof system, at least one wall panel, a floor panel, at least one corner post and at least one foundational component. The roof system, the wall panel, the floor panel, the corner post and the foundational component are configured to mechanically lock to each to form a panelized building structure consisting of structural framing and composite foam insulation. The roof system, the floor panel, the corner post, and the foundational component of the panelized building system may be configured to mechanically lock to each other through a tongue-and-groove interlocking system.

A support for a packing column having a support profile with a web section running in the vertical direction and having lower end and an upper end, and having a larger vertical extension than a horizontal extension. The support also has a foot section connected to the upper end of the web section and a head section connected to the lower end of the web section. The head section has an upper face and a sub-section, the width of the upper face being smaller than width of the sub-section and also smaller than the width of the foot section. The support enables a reduced support height and less coverage.

A strut channel support system including a first brace, a second brace, and a fastening mechanism connects at least two channel struts in a multi-orientable fashion. The first brace and the second brace both possess a U-shaped channel, a base, a fastener-engagement point, and a strut-engagement point. The base is terminally connected to the U-shaped channel, the fastener-engagement point is centrally integrated into the base, and the strut-attachment feature is integrated into the U-shaped channel. This permits the base to retain the rear portion of a strut channel. The U-shaped channel perimetrically braces the lateral sides of the strut channel. The first brace and the second brace attach to each other via the fastener-engagement point. The fastener-engagement point of the first brace and the fastener-engagement point of the second brace are mechanically coupled to each other.
