    en.wikipedia.org/wiki/Cold-formed_steel

    Cold-formed steel framing (CFSF) refers specifically to members in light-frame building construction that are made entirely of sheet steel, formed to various shapes at ambient temperatures. The most common shape for CFSF members is a lipped channel, although "Z", "C", tubular, "hat" and other shapes and variations have been used.

  5. DIN rail - Wikipedia

    en.wikipedia.org/wiki/DIN_rail

    The width of devices that are mounted on a 35 mm "top hat" DIN rail generally use "modules" as a width unit, one module being 18 mm wide. For example, a small device (e.g. a circuit breaker) may have a width of 1 module (18 mm wide), while a larger device may have a width of 4 modules (4 × 18 mm = 72 mm).

  6. Structural channel - Wikipedia

    en.wikipedia.org/wiki/Structural_channel

    The structural channel is not used as much in construction as symmetrical beams, in part because its bending axis is not centered on the width of the flanges. If a load is applied equally across its top, the beam will tend to twist away from the web. This may not be a weak point or problem for a particular design, but is a factor to be ...
