I have been working with light steel for quite some time now. The company I work for makes lightweight manufacturing machinery for companies that want to find cheaper and more sustainable ways to produce their products.
Knowing the bend allowance of the steel that we use is very important. If we poorly design our machinery, it not only affects us as a company, but our customers as well. Selling them a low quality machine that will inevitably break down will halt their production cycles.
To prevent mistakes in our products, we often times use testing strips to determine the bend allowance of our steel. We take a scrap pieces of the materials and calculate and test their bend allowance. If it passes the tests, then we go ahead and bend the steel that will be used in the finished product.
Although it costs money to test these materials before building them, the money we save in faulty products is worth it. My company takes pride in building machinery that lasts a long time. Proper testing is a way for us to maintain this quality.
