Advantages of Angle Irons
When it comes to angle irons, there are other choices that you can make, such as traditional C channels or braces. An angle iron may not always be the ideal choice, but here are three reasons why they offer superior quality and performance over other channel types:
- High Strength to Weight Ratio
- One of the problems with other kinds of channels is flimsy. Not so with the angle iron. Basically, a process of heating and rolling with a high level of carbon will result in a superior product that is much stronger than the competition. This can be used for anything from railroad rails to structural support.
- Denser Grain Structure
- During the manufacturing process of angle irons, the grain structure of the metal becomes stronger. This is done by breaking the metal into parts, reheating the parts again, rolled into larger sizes, and heated and rolled again. This creates a channel that has a strength of about 80,000 PSI and a yield strength of about 50,000 PSI.
- Modern Technology
- Roll forming angle irons is a complicated process. Computers and other technology can make the process easier. Computer-controlled furnaces can heat the metal to a much higher temperature than can be reached at hand. Multiple rolling sessions prepare the metal for the additional trials ahead. Lasers cut through the metal with the ultimate precision and can transform raw metal into the best high-strength iron angle.
- You’ll find these benefits and more when you take advantage of roll formed iron angle products.
Angle Iron Manufacturing Processes
A variety of fabrication processes can produce angle irons, but roll forming is the simplest and produces a quality, uniform product. A roll former is a machine that features a long series of rollers; these rollers can turn a metal rod into angle iron. The process begins with a stock of metal. The metal is fed into the first rollers, which grip the metal tightly. Each subsequent set of rollers is positioned to change the shape of the metal slightly. As the metal rod moves through the machine, the rollers bend the rod along the linear axis, pressing and shaping the rod. By the time the metal reaches the last roller, it has been shaped into a new angle iron. It can then be ejected, cut, and prepared for shipment. Roller dies may also include punches that punch holes or shapes into the metal; punches are often used to form slotted angle irons. The roll forming process creates very little scrap material while improving the structural integrity of the product and can be used to create angle irons and many other metal shapes of almost any size and shape.
Applications of Angle Iron
Angle Irons can be punched with holes or shapes to allow for hardware fastening. There is a direct relationship between an angle iron’s size and weight capacity; the larger the angle iron, the greater its load-bearing capacity. Angle irons are built to bear heavy loads indefinitely; they are used in building reinforcements, drawer slides, athletic flooring systems, joists, studs, control joints, and expansion joints. Construction, aerospace, automotive, railroad, furniture, HVAC, hardware, and storage operations all make use of angle irons. Materials that are used in angle irons include iron, steel, brass, and aluminum. Iron and steel angle irons are the most common, but brass and aluminum are also used in angle iron fabrication. Brass, for example, is used as a light load bearing element when the element is highly visible.
