Angle steel: the “steel skeleton” in industry and construction

Angle steel, also known as angle iron, is a long steel bar with two perpendicular sides. As one of the most fundamental structural steels in steel structures, its unique shape and excellent performance make it an irreplaceable component in a variety of fields, including industry, construction, and machinery manufacturing.

Angle Steel Classification and Specifications

• By cross-sectional shape: Angle steel can be divided into equal-leg angle steel and unequal-leg angle steel. Equal-leg angle steel has equal widths, such as the common 50×50×5 angle steel (50mm side width, 5mm side thickness); unequal-leg angle steel has different widths, such as the 63×40×5 angle steel (63mm long side width, 40mm short side width, 5mm side thickness).

• By material: Angle steel mainly comes in carbon structural steel (such as Q235) and low-alloy high-strength structural steel (such as Q355). Different materials offer varying strength and toughness, meeting the needs of different scenarios.

Characteristics and Advantages of Angle Steel

• Stable Structure: Its right-angled shape creates a stable framework when connected and supported, offering strong load-bearing capacity.

• Convenient Processing: It can be cut, welded, drilled, and processed as needed, making it easy to fabricate into a variety of complex components.

• Cost-Effective: Its mature production process results in a relatively low price, long service life, and low maintenance costs.

Applications of Angle Steel

• Construction Engineering: Used in the construction of frames for factories, warehouses, bridges, and other structures, as well as in the fabrication of doors, windows, railings, and other components.

• Machinery Manufacturing: Serving as bases, brackets, and guide rails for mechanical equipment, it provides support and guidance for operation.

• Power Industry: Widely used in transmission line towers, substation structures, and other facilities, ensuring the stable operation of power systems.

In short, angle steel, with its unique structure and excellent performance, has become an indispensable material in modern industry and construction, providing a solid foundation for the smooth implementation of various projects.
