Angle irons aren’t made of iron, although this word is in the name. This versatile item, made using galvanized steel, is used in many construction projects today. The steel is molded to form a right triangle with legs of equal or differing lengths. The perpendicular legs add strength and rigidity, making this component ideal for framing, bracing, or general support.
Why Galvanized Steel?
Manufacturers typically use galvanized steel when producing an Angle Iron because it resists oxidation and rusting. When galvanizing the steel, the manufacturer dips the angle iron in zinc. The zinc is what prevents corrosion and rusting. If the zinc and steel remain coupled, the steel is protected, even if all or part of the zinc wears off.
Angle Iron Options
Galvanized steel is the most popular material for angle irons. However, you may also purchase aluminum or stainless steel versions. Choose from a range of lengths and thicknesses, depending on the needs of the project and the load-bearing requirements. Regardless of which options are selected, the legs intersect at a 90-degree angle.
Angle Iron Uses
Where are angle irons commonly used? They are frequently found on construction sites, as they are helpful when creating structural frames. Contractors use them for large-scale projects, such as bridges and buildings. When the crew needs to add strength and stability to a structure, they often turn to angle irons. The angle irons might be used as columns, beams, or reinforcement elements.
Construction crews also turn to angle irons when they need to brace a structure. The irons provide lateral support and add rigidity to the structure. This makes them ideal for shelving units, fences, and more. A furniture maker might turn to angle irons when creating furnishings. The irons might be found on tables, chairs, and more. They are now becoming popular in modern interior design, as they add a unique and stylish touch to the decor.
Angle irons are found in other industries, as well. Heavy equipment manufacturers, for example, turn to angle irons for their frames, supports, and reinforcements. They are also ideal for manufacturing environments thanks to their strength and durability.
Fabricating Angle Irons
Manufacturers fabricate angle irons using many techniques. They may cut and shape the irons using hacksaws, angle grinders, or specialized metal-cutting saws. Workers must take safety precautions when working with this material, however. They need to wear protective gear and follow appropriate cutting techniques.
Another option when fabricating angle irons is to join or fasten the pieces. Welding, bolting, and riveting are three ways to do so. Welding is preferred when a strong, permanent connection is needed. However, if the pieces might need to be disassembled in the future, riveting and bolting are better options.
At times, the manufacturer or crew might need to drill holes in angle irons. These holes allow them to fasten components together. To guarantee a precise and secure connection, the correct bolts and tapping tools are needed.
Before using angle irons, the manufacturer or crew must determine if the surface has to be prepped. It may need to be degreased or sandblasted. At times, a protective coating is required. Preparing the surface enhances the durability of the angle iron while preventing corrosion.
Angle irons have many uses today. They are versatile and robust, making them ideal for countless construction and manufacturing projects. However, the average person may also find these components to be useful. Regardless of where they are used, they increase the integrity of the structure while offering visual appeal.
