As a net result, a "two-by" steel stud will conduct 10 times more heat than a "two-by" wood stud. Heat conductivity: Calculations show that the web of an 18-gauge steel stud is about 31 times thinner than a "two-by" wood stud however, steel conducts heat 310 times more efficiently than wood.Mold needs moist, porous material to grow. With the propagation of mold and mildew in residential building, using steel minimizes these infestations.Steel allows for improved quality of construction and less maintenance, while offering improved safety and resistance.Steel is cost effective and rarely fluctuates in price.Steel does not easily warp, buckle, twist or bend, and is therefore easy to modify and offers design flexibility.Any excess material is 100% recyclable.Steel is structurally sound and manufactured to strict specifications and tolerances.Steel provides several advantages over other building materials, such as wood: The range of application has expanded with improved materials, products and design capabilities with the availability of computer aided design software. Steel buildings have been widely accepted, in part due to cost efficiency. Their use became more widespread during World War II and significantly expanded after the war when steel became more available.

Steel buildings first gained popularity in the early 20th century. The Minor Basilica of San Sebastián (1891) in Manila
