Descriptions
Product Introduction
Angle steel, commonly known as angle iron, is a long bar steel with two sides perpendicular to each other, playing an indispensable role in many fields such as construction and machinery manufacturing. According to the difference in the specifications of the two sides, angle steel can be divided into equal-leg angle steel (two sides have the same length) and unequal-leg angle steel (two sides have different lengths, and unequal-leg angle steel is further divided into equal thickness and unequal thickness). Its specifications are usually expressed in millimeters as "leg length × leg length × thickness", such as "∠50×50×5", which refers to equal-leg angle steel with a leg width of 50 mm and a thickness of 5 mm.
Product Advantages
High Strength and Load-Bearing Capacity
Angle steel is generally processed by hot rolling or cold rolling, giving it high strength and good rigidity. When subjected to pressure, tension, and bending forces, angle steel can, due to its structural characteristics, evenly distribute the force, exhibiting strong load-bearing capacity and is not easily deformed or broken. In the construction field, whether it is used as a frame beam and column supporting the weight of an entire building in steel structure buildings, or as a load-bearing base for large equipment in machinery manufacturing, angle steel can reliably bear the corresponding load, providing solid assurance for the stability and safety of the structure.
Good Processing Performance
Angle steel is relatively easy to process; cutting, welding, and drilling can be easily achieved. Construction personnel can use common cutting equipment to accurately cut angle steel to the required length; through welding, multiple angle steels can be firmly connected to construct complex and diverse structures; and when installing components or connecting, drilling can also be smoothly completed. When building steel structure factories, the construction team can cut angle steel into different sizes according to design requirements and then quickly assemble them into a frame structure through welding, greatly improving construction efficiency and reducing construction difficulty. This good processing performance allows angle steel to flexibly meet the diverse needs of different projects.
Convenient Installation
The unique angular structure gives angle steel an advantage in installation. It can be conveniently connected to other structural components through various methods such as welding, bolted connections, or riveting. At the construction site, workers can flexibly choose the connection method according to the actual situation and quickly complete the assembly of angle steel and other components. When building temporary buildings or simple guardrails, using bolted connections for angle steel is not only simple to operate but also convenient for later disassembly and adjustment; while in some permanent building structures with higher connection strength requirements, welding can make the angle steel and other components tightly combined, forming a stable whole.
High Cost-Effectiveness
The production cost of angle steel is relatively low, its production process is mature, and the raw materials are widely available, which makes angle steel have high cost-effectiveness while meeting the needs of most projects. In construction projects, compared with some high-performance but expensive special steels, the reasonable selection of angle steel as a structural material can both ensure project quality and effectively control costs. When constructing ordinary industrial plants, warehouses, and other buildings with moderate material performance requirements, angle steel, as the main structural material, plays an important role in reducing construction costs, bringing good economic benefits to the project.
Recyclability
Angle steel is a recyclable and environmentally friendly material. When angle steel products reach the end of their service life, they can be recycled and reprocessed into new steel products through professional smelting processes, realizing the recycling of resources. This not only helps reduce reliance on primary mineral resources and reduce energy consumption but also reduces pollution to the environment caused by improper disposal of waste steel. In the current advocacy of green development and sustainable development, the recyclability of angle steel makes it more advantageous in various engineering constructions.
Multifunctionality and Customizability
Angle steel has a wide range of uses. It can be used as supports, frames, and beams in building structures, and it can also play a role in shelves, furniture, and machinery and equipment. In the production of supermarket shelves, angle steel, as a frame material, provides stable support for goods; in modern minimalist furniture, angle steel is often used to make table and chair frames, showing a unique industrial style. In addition, angle steel can be customized according to different needs. By adjusting the size, shape, and material, it can meet the special requirements of different projects. In some special building structural designs or high-precision machinery manufacturing, customized angle steel can precisely match engineering needs, improving the applicability of materials and the overall quality of the project.
