Information summary：Angle iron (also known as angle steel) is a commonly used profile in the construction industry, with a right angled L-shaped cross-section. It is divided into equilateral angle steel (with equal width on both sides) and non equilateral angle steel (with different width on both sides). Due to its stable structure, high cost-effectiveness, and convenient installation, it is widely used in the field
Angle iron (also known as angle steel) is a commonly used profile in the construction industry, with a right angled L-shaped cross-section. It is divided into equilateral angle steel (with equal width on both sides) and non equilateral angle steel (with different width on both sides). Due to its stable structure, high cost-effectiveness, and convenient installation, it is widely used in the field of construction. The specific scenarios are as follows:
1、 Structural support and framework construction
Lightweight load-bearing frame: In small buildings such as warehouses, simple factories, and temporary sheds, angle irons are often used as connectors or auxiliary supports for columns and beams to form a complete frame structure, bearing some vertical or horizontal loads.
Steel structure auxiliary components: In large steel structure buildings (such as steel structure factories and sports halls), angle irons are used to reinforce the nodes of the main frame or as supporting members for secondary beams and purlins, enhancing the overall stability of the structure.
Brackets and brackets: such as air conditioning outdoor unit brackets, billboard brackets, pipeline brackets, etc., angle iron is welded or bolted to form a triangular support structure, using its bending resistance to bear the weight of equipment or pipelines.
2、 Wall and floor reinforcement
Wall keel reinforcement: In lightweight partition walls (such as light steel keel partition walls), angle iron can be used to connect the keel with the fixed nodes of the ground and wall to prevent deformation of the wall due to vibration or force, especially suitable for areas with high stability requirements (such as kitchens and bathrooms).
Edge reinforcement of floor slabs: At the edges and corners of prefabricated or cast-in-place floor slabs, angle irons can be welded as reinforcement bars in the steel skeleton to enhance the crack resistance and load-bearing capacity of the floor slab, avoiding cracking at the edges due to stress concentration.
3、 Pre embedded parts and connection fixation
Basic embedded parts: In building foundations or concrete components, angle irons are pre embedded as connecting pieces to facilitate welding or bolt connections with steel structures, equipment bases, etc. (such as fixing crane tracks and connecting curtain wall keels).
Component connection node: The right angle characteristic of angle iron makes it an ideal "connector", for example, in the installation of door and window frames, angle iron is used to fix the gap between the frame and the wall; In the construction of scaffolding, angle iron serves as a right angle connector between the horizontal bar and the vertical bar, enhancing the stability of the scaffolding.
4、 Protective and decorative components
Protective railings and fences: In areas such as balconies, stairs, terraces, etc., angle irons can be used as the skeleton of protective railings, welded to form a grid or frame structure. The outer layer can be coated with anti rust paint or wrapped with decorative materials (such as wood and plastic), balancing safety and aesthetics.
Exterior decoration of buildings: In industrial style buildings or retro style designs, angle iron can be directly used as a decorative element to outline wall lines, build decorative frames, or combine with glass and metal panels to form unique exterior shapes.
5、 Temporary facilities and auxiliary engineering
Construction scaffold accessories: during scaffold construction, the angle iron can be processed as the connecting piece of the bottom broom and slant support to enhance the overall rigidity of the scaffold and ensure construction safety.
Template support reinforcement: During concrete pouring, angle irons can be used to reinforce the corners or edges of the template to prevent deformation due to lateral pressure from the concrete and ensure correct dimensions of the component.
