After several emails and phone calls going back and forth for the design of his 101 ½” by 72” gate opening, he approved the design and digitally signed invoice contract on 4/25/18. We fabricated his gate, posts, and side panels according to his approved design measurements and sent it out for powder coating in the color he chose. We then packaged his gate order on a pallet and shipped it out to him. There was no damage in transit. The issues he raised had nothing to do what we agreed upon in the invoice and design.

Around 1717: People can obtain cast iron by using pit coal and then compensating to the shortage of wood. It allows for more complex shapes like rounds, squares, rails, and double-T beams.
1801: Aluminum and the steam hammers inventions end the Iron Era.
By 1472, at the age of twenty, Leonardo qualified as a master in the Guild of St Luke, the guild of artists and doctors of medicine, but even after his father set him up in his own workshop, his attachment to Verrocchio was such that he continued to collaborate with him. Leonardo’s earliest known dated work is a drawing in pen and ink of the Arno valley, drawn on 5 August 1473.
Little is known about Leonardo’s early life. He spent his first five years in the hamlet of Anchiano, then lived in the household of his father, grandparents and uncle, Francesco, in the small town of Vinci. His father had married a sixteen-year-old girl named Albiera, who loved Leonardo but died young. In later life, Leonardo only recorded two childhood incidents. One, which he regarded as an omen, was when a kite dropped from the sky and hovered over his cradle, its tail feathers brushing his face. The second occurred while exploring in the mountains. He discovered a cave and was both terrified that some great monster might lurk there, and driven by curiosity to find out what was inside.
This article is focused on tracing a synthetic history of sheet metal and its machining. We must first of all distinguish three fundamental aspects, distinct but deeply interconnected:
-the production of the raw material, in particular steel;
-the thin sheet fabrication;
The metal working is an ancient art. There are witnesses that, already millennia before christ, metals were known and worked. Let’s just remind the previous gold and silver jewels that we find in so many museums, dating back to the fourth-fifth millennium b.c. considering that the evolution of the metal processing depends on several competences: chemical, physical, technological etc. It is easy to understand that it is extremely complex.
