Angle Iron weight-per-foot is a standard commercial measurement utilized for the buying and selling of large amounts of angle iron and in different base weights or lengths. Although the factors used to determine weight-per-foot for angle iron are identical to those used for other metals, the results themselves are not identical since the density of different types of metals varies and the overall
. weights are not uniform. When determining weight-per-foot for a bulk purchase of angle iron, transportation costs per a set amount of bulk weight are a considerable factor in figuring the overall cost of a project.Weight-per-foot implies length as the only physical dimension of size used in bulk determination, however, wall thickness, height and width are also dimensions considered in factoring the total weight of angle iron. Since angle iron is cut by manufacturers to stock lengths, such as 20 feet per bar, weight-per-foot is used to determine prices for an individual foot length of iron since most purchases require cutting of stock bars. There is not a universal weight for angle iron in weight-per-foot since the overall thickness of the angle iron walls often varies from one piece to another; therefore, weight-per-foot is reliable when calculated each time there is a change to the thickness of a piece of angle iron.The mathematical formula for plates, sheets and flats is: thickness x width x 3.45 = weight in pounds-per-linear-foot. This formula is only practical for solid plates, sheets and flat pieces of metal and other mathematical formulas are needed for pieces of iron that are hollow or in unusual shapes, such as hexagons, octagons and pieces of metal that are round.Once the weight-per-foot is reckoned, the overall cost of a particular quantity of angle iron is figured by multiplying the cost-per-weight-per-foot by the number of feet required for purchase.More reference links: http://www.dixiepipe.com/weightperfoot.html http://bushwickmetals.thomaswebs.net/formulas.html
