Leading Steel Angle Manufacturers

In essence, hot-rolled carbon steel or high strength low alloy steel is used to create a steel angle, also known as an angle iron or a steel angle bar. It features an L-shaped part with two legs that might be equal or uneven at a 90-degree angle. Angles made of structural steel come in various sizes to accommodate various needs. Read More…

Steel Angles Steel angles are shapes formed by a bend in a single piece of steel or the intersection of two pieces of steel. An aluminum angle can in theory measure anywhere between 0 and 180 degrees, though in practice most steel angles measure near 90 degrees.

The most common and fundamental roll-formed steel type is steel angles, which are the building blocks of steel manufacture. A steel angle is frequently used in building and design and can be used in various ways. For example, steel angles are frequently used in framing, brackets, and reinforcements across various sectors. They are particularly adaptable since they can usually be trimmed to size.

Steel Angle Sizes

Angles can also exist in versions that are equal or unequal. So said, equal angles have equal-length legs, but unequal angles have different-length legs. One choice may be more beneficial or practical depending on the project and dimensions requirements. For example, steel angles can have thicknesses ranging from 1/8" to 1-1/8" and leg sizes ranging from 1/2" to 8". Since the two leg dimensions and the thickness are the only information included in the standard size format for steel angles, reading it is relatively easy. For instance, an equal angle with legs of 4 inches and a thickness of 1/8 inches is 4" x 2" x 1/8.”

Unequal and Equal Steel Angles

Application of Steel Angles


Any component of a bridge may be made out of steel angles. The angles for the deck can strengthen the concrete and reduce the number of materials that builders must handle. In addition, steel angles are utilized in bridge parts, including girders, bearings, and arches or pedestrian pathways. Using steel angles without additional coating or protection is uncommon in a given building.

As a result, most steel angles commonly are powder coated or galvanized. Powder coating is a surface finish of electrostatic-spray deposited (ESD) resins. The galvanization process, meanwhile, forms a corrosion-resistant layer on the material. As a result, steel angles with a protective coating boost the material's longevity.

Steel Angles in Truss Bridge


Steel angles can be used to support the roof of a building, build a mezzanine system, or serve as the framework for a warehouse. Steel angles are capable of supporting the raised flooring needs of mezzanines. These items can withstand a range of weights and impacts caused by the machinery and storage units utilized in the warehouse.

This strength and impact resistance are true regardless of the kind of mezzanine, whether it is freestanding, rack-supported, attached to columns, or shelving-supported. Steel angles are vital for ceiling or roofing construction in low-cost warehouses. The network of rafters that shields the warehouse from varying wind loads can be completed by connecting steel angles with various steel accessories, such as flat bars, rods, couplings, purlins, and fittings.

Steel Angle Slotted Racks


Framing various buildings and objects is a common application for steel angles. It is possible to build the basic design, which consists of an equal (or non-equal) angled L-shaped cross-section with two opposing legs, to get the desired look. A steel angle can have several apertures made on it using metal stamping or punching, for example, to provide a decorative framing element. Steel angle framing may also hold handrails, utility carts, interior moldings, trims, paneling, cladding, and many more custom-built designs.

Equipment Manufacturing

Until now, steel, in one form or another, has been used to manufacture most electrical equipment.. Forklifts, bulldozers, road rollers, and excavators are a few examples of powerful machines that use steel angles. Steel angles may even reinforce home appliances; their distinctive form protects the corners of stoves, ovens, washing machines, and dryers. Steel angles have significantly reduced costs for both equipment manufacturers and consumers. For instance, manufacturers rely on cheap and simple-to-produce material. Steel is also thought to be easily accessible and may be used again without losing any of its chemical or physical qualities.

Benefits of Steel Angles


Contrary to appearances, steel is among the most environmentally friendly building and construction materials. Steel is among the most recyclable materials, with about 90% of steel being made from recycled components. Steel is entirely recyclable and requires little processing, which has no effect on its potential to be reused. The carbon footprint of steel has roughly lowered by 50% during the past ten years. The quantity of energy needed to produce steel has dramatically decreased during the last 30 years. Very little water is used in the production of steel.


Steel is typically the most cost-effective construction material. Over the past 30 years, productivity rates have risen significantly due to advancements in steel manufacturing methods. Steel is a far more cost-effective basic material since it can be manufactured in less time and as a singleton. The cost of steel is finally dropping significantly because of advancements in steel manufacturing and finishing methods.


Because it can be twisted and shaped into many different shapes, steel is among the strongest construction materials in terms of structural strength. The chemical composition, production process, and heat treatment of steel are only a few variables that affect its mechanical properties. Construction steel primarily consists of iron, but additional alloys like manganese and niobium may greatly increase the steel's strength.

Although adding these elements may make steel stronger, it may also affect other properties like elasticity and weldability. Mechanical processing also impacts steel's overall strength; in principle, the more steel gets "rolled," the more robust it becomes.

Choosing the Correct Steel Angle Company

To make sure you have the most productive outcome when purchasing steel angles from a steel angle company, it is important to compare at least 5 companies using our steel angle directory. Each steel angle company has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the company for more information or request a quote. Review each steel angle company website using our proprietary website previewer to get an idea of what each company specializes in, and then use our simple RFQ form to contact multiple steel angle companies with the same message.
