Angle steel, also widely recognized as angle iron, is a versatile long steel strip characterized by its distinctive perpendicular sides. Here, we delve into the detailed attributes of angle steel:
1, Classification and Specifications
Angle steel is predominantly categorized into two distinct types: equilateral angle steel and unequal angle steel. Equilateral angle steel features equal length sides, and its specifications are denoted in millimeters as 'edge width x edge width x edge thickness', such as '∠ 30 x 30 x 3', indicating a 30mm wide and 3mm thick equilateral angle steel. Conversely, unequal angle steel provides diversity and adaptability with its differing side lengths.
Domestic angle steel specifications range from 2 to 20 centimeters, with the side length indicated by the number of centimeters. A single angle steel often offers 2 to 7 varied edge thicknesses. Imported angle steel must display the precise dimensions, edge thickness on both sides, and adhere to pertinent standards.
2, Production Method
Hot Rolling: This is the predominant method for angle steel production, catering to standard sizes and substantial quantities efficiently.
Cold Drawing: Ideal for manufacturing angle steel with precise dimensions and rigorous tolerances, this method ensures enhanced strength and superior surface quality.
Forging: Primarily used for crafting large-scale or specially specified angle steel, forging enhances grain structure and performance.
3, Features and Applications
Renowned for its excellent weldability, plastic deformation capacity, and mechanical strength, angle steel is a carbon structural steel pivotal in construction, classified under simple section steel.
Angle steel finds extensive application across a multitude of building and engineering projects, including beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and storage solutions.
Furthermore, angle steel adapts to various structural requirements, forming a myriad of load-bearing elements or serving as essential connectors between different components.
4, Other Information
The critical chemical composition indicators for angle steel include C, Mn, P, and S, each with specific content variations.
Angle steel delivery length is classified into fixed and double length categories. In domestic production, the fixed length selection range varies with specification numbers.
The weight of angle steel can be estimated using the formula: weight per meter = 0.00785 × (edge width + edge width - edge thickness) × edge thickness. However, this calculation is approximate, with actual weight best verified through a hardware manual.
In conclusion, angle steel serves a crucial role across numerous sectors, attributable to its distinct shape and outstanding mechanical qualities.
