Manufacturers of perforated galvanized angle iron also cater to the automotive and aerospace industries, where lightweight yet robust materials are crucial
. The ability to customize the dimensions and hole patterns in the angle iron allows engineers to design components that meet specific load-bearing and weight requirements, ultimately enhancing the overall performance of vehicles and aircraft.Civil engineers in Rome invented the concept of underground sewer to rid their cities of plagues caused by human contact with waste. Their water sources that they used for consumption were also contaminated as they served as open sewers. The underground sewers made sure that that waste stayed out of reach of humans and was deposited by these sewers further downstream. For periodic cleaning, they also provided access ways that were covered with stone lids that we call manholes today. Incidentally, these stone access way covers are still seen in Jerash, Jordan which was a Roman city in the old days.
