，Key word 是： Unequal Angle Steel
Unequal angle steel, also known as L-shaped angle steel, is a steel product with an unequal length and unequal thickness and is made up of two components: the long side and the short side. Unequal angle steel is mainly used for carriages, bridges, iron towers, lifting machinery, ships, and large steel structures. Due to its large variety of shapes and related properties, it has been widely used in the construction industry for a long time.
Unequal angle steel is a steel angle with unequal sides. It is mainly composed of two parts: the long side and the short side. The long side length is larger than the short side length, and it is an oblique angle steel distributed in a wide range. The size range of unequal angle steel length is 65mm--500mm, and the thickness is 3mm--24mm.
Unequal angle steel is divided into two types: hot rolled and cold rolled. Hot-rolled unequal angle steel has good centrifugal function, the surface is smooth and neat, but the internal structure is relatively loose, and there are some flaws such as trachoma. Cold-rolled unequal angle steel has high precision and good mechanical properties, but its cost performance is higher than that of hot-rolled type.
Unequal angle steel is mainly used in the steel structure, construction of large span buildings, bridges, cars, ships and industrial production. It is a kind of structural steel with good mechanical properties, excellent welding performance, plasticity and cold bending performance, processability and good fatigue resistance. In addition, it has reasonable price and easy to process, so it is widely used in engineering projects.
In addition to being used as steel structure components, due to its excellent corrosion resistance and mechanical properties, unequal angle steel is also used for a variety of manufacturing applications, such as furniture frames and equipment.
The weight of unequal angle steel is mainly determined by the size of the steel. The larger the steel, the heavier the weight. The weight of the unequal angle steel is related to its specific gravity, the specific gravity of the metal, the cross-sectional area, and the length.
In order to ensure the quality of unequal angle steel, it is necessary to conduct a series of tests, such as expanding test, tensile test, hardness test and density test. These tests can provide us with the necessary information and guarantee the quality of the unequal angle steel.
Unequal angle steel has many advantages, such as good mechanical properties, high rigidity, excellent welding properties, good plasticity and low cost. In addition, it can be easily formed and cut, making it easy to use.
Therefore, unequal angle steel is widely used in bridge, building and other engineering projects. It can bear heavy loads and ensure the stability and safety of the overall structure.
