The 1872 George Peabody Library in Baltimore is a similarly elaborate atrium with glass roof, where all the structural members are also decorative and made of cast iron. The lofty glass roof of Milan's Galleria, built 1865–77, is both a dome and glass roofed shopping arcade, the grandest ever built. [22]
A less-known precursor to the modern steel frame construction, the four-storey Boat Store ("Shed 78", 1858–1860), has its rigid frame constructed also from cast iron columns and wrought iron girders. With no internal walls and external walls made from sheet metal, the stability of this structure is provided exclusively through the rigid ...
Interior partition walls made with cold-formed steel. Cold-formed steel frames are also known as lightweight steel framing (LSF). Thin sheets of galvanized steel can be cold formed into steel studs for use as a structural or non-structural building material for both external and partition walls in both residential, commercial and industrial construction projects (pictured).
Lime is an inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. [1]
Limestone is a major industrial raw material that is in constant demand. This raw material has been essential in the iron and steel industry since the nineteenth century. [126] Companies have never had a shortage of limestone; however, it has become a concern as the demand continues to increase [127] and it remains in high demand today. [128]
The use of glass in architectural buildings has become very popular in the modern culture.

Later, mortar and plaster were used, especially in the construction of city walls, castles, and other fortifications before and during the Middle Ages. These stone walls are spread throughout the world in different forms.
