1. Durability

Steel is dimensionally stable and does not expand or contract with changes in moisture content. Steel will not warp, split, crack or creep when exposed to the elements.

  • Wood or brick will swell when exposed to moisture
  • Wood will warp, crack, chip, split and spall when it’s dried
  • Concrete and concrete block will shrink and form shrinkage cracks

And, dimensional stability concerns are magnified when materials other than CFS are used in tall mid-rise buildings.

2. High Tensile Strength

Steel has the highest strength-to-weight ratio of all structural framing materials, according to the Steel Framing Industry Association.

When CFS sheet is formed into a C-shape, like a stud or a joist, the folds act as stiffeners that increase the strength of the steel sheet dramatically. This gives CFS framing components a strength-to-weight ratio that is up to 7 times greater than that of dimensional lumber, for example.
