I believe with this measurement I'm seeing someone as given u the price because this is accurate measurement, measured by a profession aluminum fabricator, oga go and give the guy who measure it the job, u see the more u keep asking abt price of a job the more the job is at risk reason at the end now someone will give u #1000 and u asked another is own price will be like #900 while another is #750 because they don't want to lose the job, I believe at the end of ur pricing u will give it to #750 price and u want the same quality the #1000 price should used the same quality the#750 should used, no it can't possible there are differences of materials at the end u wouldn't get original, please forgive me of I'm rude
