Which one of the following is NOT among the characteristics of light gauge steel frames? A. Thermally inferior in itself. B. Susceptible to decay and termites. C. Dimensional stability unaffected by humidity. D. Noncombustible, enabling its use in higher construction types and larger buildings.

C. Dimensional stability unaffected by humidity

Explanation:

very wide range of lightweight structural sections are produced by cold forming thin gauge strip material to specific section profiles. These are often termed light gauge or cold formed steel sections. In most cases, galvanized steel strip material is used.

Light gauge steel structures have many of the advantages of light wood framed structures: They are light, and allow quick building without heavy tools or equipment. Every component can easily be carried by hand - a house is like a carpentry job on a larger scale.

Light framed structures allow the passage of sound more readily than the more solid masonry construction.

Light gauge steel will lose strength in the advent of fire. Adequate fire protection must be used.

Light gauge steel structures are non-combustible, which is a code requirement for some types of structures.
