on Historically, who started sheet metal work?
A Brief History of Sheet Metal Work
Sheet metalwork is a process that has been around for centuries. In its earliest incarnation, sheet metal was used to create swords and other weapons. Over time, the process evolved, and sheet metal began to be used for other purposes, such as creating roofing materials and ductwork. Today, sheet metal work is essential to many industries, including construction, automotive, and aerospace.
The Earliest Uses of Sheet Metal Work
The first known use of sheet metal dates back to 4000 BC when it was used to create swords in ancient Mesopotamia. Then, around 1000 BC, Chinese metallurgists began using a process known as annealing to make weapons and tools from iron and steel. This process made the metal softer and more pliable, which made it easier to work with.
By the Middle Ages, European blacksmiths had discovered how to make steel, which was even stronger than iron. This new material quickly became famous for making armour and weapons. To make steel, blacksmiths would heat iron until it glowed red hot before dipping it into water or oil. This process, known as quenching, made the steel harder and more durable.
The Industrial Revolution and Beyond
The industrial revolution ushered in a new era for sheet metal work. With the advent of new technologies like the steam engine and the cotton gin, factories began popping up all over Europe and North America. These factories required large amounts of metal for their machinery, which created a demand for sheet metal workers.
With the advent of new technologies like the rolling mill and the steam engine, manufacturers could mass-produce sheet metal much more efficiently than ever before.
As factories sprang up across the continent, so did the demand for skilled workers who could shape and manipulate sheet metal into the needed parts and pieces. These workers became known as “tin bashers,” a term still used today in some parts of the world.
Tin bashers were in high demand throughout the 19th and early 20th centuries as factories continued to churn out an ever-increasing number of products made from sheet metal. However, the rise of automated manufacturing processes in the mid-20th century led to a decline in the demand for manual labour, including tin bashers.
One of the most famous examples of early sheet metal work is the dome of St. Paul’s Cathedral in London, completed in 1708. The dome is made from over 3,000 tons of copper hammered into shape by hand. The Statue of Liberty is another well-known example of early sheet metal work; her outer skin is made from sheets of copper that were heated and bent into shape.
Today, sheet metal work is essential to many industries, including construction, automotive manufacturing, and aerospace engineering. New technologies have led to the development of automated machines that can accurately cut and shape sheet metal. However, there are still many instances where manual labour is required to create a custom piece or achieve a particular look.
Conclusion:
Sheet metal work is a fascinating field with a long and rich history. What started as a way to create swords and other weapons have become an essential part of many industries today. While new technologies have led to the development of automated machines that can cut and shape sheet metal with precision and accuracy, there are still many instances where manual labour is required to create a custom piece or achieve a specific look. Whether used to develop ductwork or the outer skin of an airplane, sheet metal work plays an important role in our world today.

While the term titanium sheet metal fabrication often conjures thoughts of modern industry and manufacturing, the practice of sheet metal fabrication actually dates back to ancient Egyptian jewelry. Through a combination of naturally found metals and prehistoric techniques, gold and silver-workers were able to craft a form of fabrication that served as the foundation of techniques used today.
Let’s take a look back at the timeline of history to see how titanium sheet metal fabrication became the invaluable manufacturing technique it is today.
Around the beginning of the 15th century, metalworkers stopped using primordial furnaces to pile alternated layers of charcoal and iron to liquefy steel. It was also during this century that Leonardo da Vinci first sketched his idea for a rolling mill, an incredibly advanced idea for its time.
In fact, it wasn’t until the early 16th century that the first recorded reports of two rolling mills were noted by historians. One was designed to produce uniform gold sheets that were used in the creation of coins, while the other was designed to cut previously formed sheets into strips. Over 100 years after drawing his sketch, Da Vinci’s rolling mill is finally brought to life in 1590 by utilizing two heavy cylinders to press different types of metal, thereby altering thickness.
Of course, with innovation often comes failure. The beginning of the 17th century saw the invention of commonly used – but flawed – sheet metal fabrication technique puddling.
Puddling involves the heating of cast iron in reverberation furnaces until the metal becomes liquefied. One of the biggest problems with puddling was that nearly half of the iron was drawn off the slag because sand was used for the bed. The puddling process was so inefficient that it wasn’t until the mid-1800s that the technique was refined enough to produce even mild steel. Despite the limitations of puddling, the technique was still used in the creation of the wrought iron used in the construction of both the Eiffel Tower and the Statue of Liberty.
Around 1717, manufacturers started to produce cast iron by using pit coal as their primary heating source. This technique allowed for the creation of more complex shapes like rails, squares, rounds, and double-T beams.
The Industrial Revolution 40 years later saw a huge surge of in the demand for sheet metal work. With the development of new inventions like the press brakes and assembly line, sheet metal workers were able to increase production of higher quality parts. In 1770, Swiss engineer Jean Pierre Droz successfully perfected the sheet metal process, allowing for the simultaneous production of singing, reverse, and obverse.
As the innovations continued to roll along, the beginning of the 19th century saw the invention of the steam and aluminum hammers, leading the start of a new age in iron production. By 1857, the Bessemer converters becomes the first inexpensive process to that allows for the mass production of steel from cast iron.
As technology advanced, so too did industry. In 1861, the merger of multiple unions, including the General Tramping Union of Tinplate Workers, leads to the founding of the General Union of Braziers and Sheet Metal Workers in the U.K. and Ireland.
While the sheet metal industry continues to grow over time from simple sketch to a billion dollar industry, our team at APIAMS will continue to honor the tradition of innovation and quality that has long been a part of this proud industry. The future of titanium sheet metal fabrication techniques, technology, and projects is incredibly exciting, and our team at APIAMS cannot wait to be part of such an incredible industry.
