Angle steel, often referred to as angle iron, is a robust long strip of steel featuring two sides perpendicular to one another. Here's an in-depth exploration of its features and benefits:
1, Classification and Specifications
Angle steel is primarily categorized into equilateral and unequal types. Equilateral angle steel boasts equal side lengths, with its dimensions denoted in millimeters, such as "∠ 30 x 30 x 3," indicating 30mm width and 3mm thickness. Unequal angle steel offers diverse side lengths, enhancing its adaptability and versatility for various projects.
Domestic angle steel specifications range from 2 to 20 centimeters, with side lengths measured in centimeters. A single angle steel may feature 2 to 7 distinct edge thicknesses. Imported varieties clearly state precise dimensions and edge thickness on both sides, adhering to relevant industry standards.
2, Production Method
Hot Rolling: This predominant angle steel production process excels in producing standard sizes and large quantities efficiently.
Cold Drawing: Ideal for crafting angle steel with precise dimensions and stringent tolerances, this method ensures enhanced strength and superior surface finish.
Forging: Tailored for large or specialized angle steel, forging enhances grain structure and elevates overall performance.
3, Features and Applications
Angle steel is renowned for its excellent weldability, plastic deformation capacity, and mechanical strength. It serves as carbon structural steel in construction, featuring straightforward section profiles.
Extensively utilized in myriad construction and engineering frameworks, angle steel is pivotal in beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.
Thanks to its versatile design, angle steel forms vital load-bearing components tailored to diverse structural requirements and serves as key connectors between elements.
4, Other Information
Key chemical composition indicators for angle steel include C, Mn, P, and S, each with varied concentrations.
Angle steel is distributed in fixed or double lengths. The fixed length range for domestic angle steel is contingent upon specification numbers.
The weight of angle steel is estimated with: weight per meter = 0.00785 × (edge width + edge width - edge thickness) × edge thickness. However, refer to the hardware manual for precise weight.
In conclusion, angle steel's unique configuration and outstanding mechanical attributes establish its critical role across various sectors.
