The material was rarely used for the columns, as the cast was both stronger under compression and cheaper, so a typical iron frame building in the second half of the 19th century had cast iron columns and wrought iron beams. Columns at the Crystal Palace (1851), as well as short trusses, were made from the cast iron, while longer beams used ...
Early gallery designs were inspired by wrought-iron balcony railings, featuring patterns like the cathedral arch and scrollwork. Cast iron posts were used to support the extended galleries. A surviving example can still be observed at 529–531 Governor Nicholls Street. [13] Highly ornate multi-story cast-iron galleries appeared in the 1850s.
Cast iron was also taken up by some architects in the early 19th century where smaller supports or larger spans were required (and where wrought iron was too expensive), notably in the Royal Pavilion in Brighton, designed by John Nash and built between 1816 and 1823, where cast iron columns were used within the walls, as well as cast iron beams ...
Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure.
Modern blacksmiths use scrolls in ornamental wrought-iron work gates and balustrades, and they have formed the basis of many wallpaper designs. Applications of single scroll forms can be seen in the volutes at the head of an Ionic column , the carved scroll at the end of the pegbox on instruments in the violin family (resembling fiddleheads in ...
The central "web" of the steel I-beam is often wider than a column web to resist the higher bending moments that occur in beams. Wide sheets of steel deck can be used to cover the top of the steel frame as a "form" or corrugated mold, below a thick layer of concrete and steel reinforcing bars. Another popular alternative is a floor of precast ...
They found that the pillar, primarily made of wrought iron, has a high phosphorus content (about 1%), and lacks sulfur and magnesium, unlike modern iron. Additionally, ancient craftsmen used a ...
An arc of Phoenix Columns adorns a plaza outside the old foundry building. The Phoenix Column, patented by Samuel Reeves in 1862, was a hollow cylinder composed of four, six, or eight wrought iron segments riveted together. The resulting column was much lighter and stronger than the solid cast iron columns of the day. [9]
