Angle steel, an iconic staple in the world of construction, emerges as a long, resilient strip of steel characterized by its perpendicular sides, affectionately known as angle iron. Dive into the world of angle steel as we explore its intricate details:
1, Classification and Specifications
Angle steel is artfully divided into two main categories: equilateral angle steel and unequal angle steel. With equilateral angle steel, both sides boast equal lengths, defined meticulously in millimeters as "edge width x edge width x edge thickness". For instance, "∠ 30 x 30 x 3" signifies an equilateral angle steel with a precise edge width of 30 millimeters and an edge thickness of 3 millimeters. On the other hand, unequal angle steel, with its unequal side lengths, offers unparalleled flexibility and adaptability.
The domestic realm of angle steel beckons with specifications ranging from 2 to 20 centimeters in side length, each number representing the side's length in centimeters. Each piece of angle steel may boast 2 to 7 varying edge thicknesses. When it comes to imported angle steel, clarity is key, as actual dimensions and edge thickness on both sides, along with pertinent standards, are meticulously indicated.
2, Production Method
Hot Rolling: The quintessential method for angle steel production, hot rolling is perfect for crafting standard sizes and mass-producing angle steel efficiently.
Cold Drawing: This technique is ideal for creating angle steel with refined dimensions and exacting tolerances, offering enhanced strength and superior surface quality.
Forging: Primarily employed for the production of large-scale or specially tailored angle steel, forging ensures superior grain structure and significantly boosts overall performance.
3, Features and Applications
Angle steel triumphs with exemplary weldability, commendable plastic deformation capabilities, and reliable mechanical strength. As a stalwart carbon structural steel, it shines in construction, standing proudly within the cadre of simple section steel.
Angle steel finds its true calling across a vast array of building and engineering marvels, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial kilns, reaction towers, container racks, and warehouses.
Furthermore, angle steel can be seamlessly assembled into diverse load-bearing components tailored to a range of structural demands, while also serving as robust connectors between various components.
4, Other Information
The cornerstones of angle steel's chemical composition verification are C, Mn, P, and S, each with distinct concentration levels that are rigorously monitored.
Angle steel is offered in delivery lengths of two types: fixed length and double length. For domestically produced angle steel, the selection of fixed lengths varies by specification number, providing flexibility to meet diverse project requirements.
The weight of angle steel is adeptly calculated using the formula: weight per meter = 0.00785 × (edge width + edge width - edge thickness) × edge thickness. This formula provides an approximate weight, yet true accuracy can only be achieved through reference to the hardware manual.
In conclusion, angle steel holds a pivotal position across numerous domains, celebrated for its distinctive shape and outstanding mechanical prowess, making it an indispensable asset in construction and beyond.
