Steel frame such as in interior construction where the members serve as framing for demising walls between rooms. The wall finish is anchored to the two flange sides of the stud, which varies from 1-1/4" to 3" thick, and the width of web ranges from 1-5/8" to 14". Rectangular sections are removed from the web to provide access for electrical wiring. Steel mills produce galvanized sheet steel, the base material for the manufacture of cold formed steel profiles. Sheet steel is then roll-formed into the final profiles used for framing. The sheets are zinc coated (galvanized) to prevent oxidation and corrosion. Steel
Aluminium-conductor steel-reinforced cable are normally galvanized, or coated with another material to prevent corrosion. The diameters of the strands used for both the aluminum and steel strands vary for different ACSR conductors. ACSR cable still depends on the tensile strength of the aluminium; it is only "reinforced" by the steel. Because of this, its continuous operating temperature is limited to , the temperature at which aluminium begins to anneal and soften over time. Cable which relies entirely on the steel for strength, and so can be used at temperatures up to , is called aluminium-conductor steel-supported (ACSS). The standard steel core used for
