Angle Steel Bar
Angle steel bar, also known as angle iron and equal steel, is a long strip of steel with two sides perpendicular to each other and forming a certain angle. There are equilateral angle steel(also as known Mild Steel Equal Angle) and Unequal Angle Steel Bar. The two sides of an equilateral angle are equal in width. The raw material billet for angle steel production is low carbon square steel billet, and the finished angle steel is delivered in a hot-rolled, normalized or hot-rolled state.

Applications and standards of Angle Steel Bars:
Angle steel can be used to form various stress-bearing components according to different structures, and can also be used as a connector between components.
Angle Steel Bar is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench brackets, power pipelines, busbar bracket installation, etc. Warehouse shelves, etc.
1. Building and Civil Engineering: Angle steel bars are used in factory frames, building beams and columns, stair treads, retaining wall corner protectors, scaffolding, warehouse shelves, and door and window reinforcement; especially in steel-structured residential buildings, bridge trusses, and tower crane booms as load-bearing or connecting components.
2. Power and Communication Facilities: Angle steel bars are used in the fabrication of transmission towers, substation frames, cable trench supports, and communication base station support structures due to their stable compressive and torsional resistance.
3. Machinery Manufacturing and Industrial Equipment: Angle steel bars are used as machine tool bases, equipment supports, conveyor frames, reaction tower internals, container supports, and robot trusses, facilitating welding and modular assembly.
4. Transportation: Angle steel bars are used in ship deck frames, vehicle chassis, railway track components, bridge railings, and port lifting machinery.
5. Special Environment Applications: Stainless steel angle bars are used in corrosive environments such as chemical pipeline supports, offshore platforms, and sewage treatment plants; fiberglass angle bars are used in lightweight, corrosion-resistant applications (such as anti-corrosion gratings and insulating supports).
6. Other applications: Angle steel bars are used in various applications, including shelf uprights, billboard bases, holiday decoration frames, and even simple furniture and agricultural facilities, due to their ease of processing, low cost, and high rigidity.
