Aluminium corner extrusion profiles
Aluminum corner extrusion profiles are industrial aluminum profiles with a vertical angle of 90 °, which can be divided into equal corner aluminum and equal corner aluminum according to the proportion of side length. The two sides of aluminum with equal corners are equal in width. Its specification is based on the side width × Side width × The side thickness is expressed in millimeters. Such as "∠ 30 × thirty × 3 ", which means equal corner aluminum with a side width of 30mm and a side thickness of 3mm. It can also be expressed by the model, which is the centimeter of the side width, such as ∠ 3 #. The model does not indicate the dimensions of different edge thicknesses in the same model, so the edge width and edge thickness dimensions of angular aluminum shall be filled in completely in the contract and other documents, and it is avoided to use the model alone. According to the processing method, it can be divided into aluminum plate bending angle aluminum and extrusion angle aluminum profile. It should be noted that the strength of aluminum plate bending angle aluminum is far lower than that of pressurized profile angle aluminum.
The specification marking method of aluminum corner extrusion: it is usually measured in mm, such as angular aluminum with 100mm on one side and 200mm on the other side, and 5mm thick. We usually mark ∠ 100 × five hundred × 5。
Processing of aluminum corner profiles: angular aluminum belongs to a category of industrial aluminum profiles and also belongs to extrusion processing. Generally, angular aluminum is in T5 or T6 state, and its hardness will be greatly improved after heat treatment. It is mainly used in construction, machinery manufacturing, hardware processing and other industries. Chalco aluminum sells various specifications of angular aluminum. Non standard sizes and specifications can be customized by opening molds. It has the advantages of short delivery time and small starting quantity. It can provide sawing small-size angular aluminum of various lengths, anodized angular aluminum and other related deep-processing products. Users at home and abroad are welcome to call and consult. There are two common ways to fix angle aluminum into processing angle parts: one is punching connection, and the other is welding. These two connection methods have their own characteristics. Punching connection is a common connection method used by aluminum profile manufacturers. This method needs to drill holes in the corresponding position of angle aluminum in advance, and then connect with bolts and nuts. Connecting bolts and nuts mostly use hexagon socket bolts + T-nuts, half round head bolts + T-nuts. The angle aluminum connected in this way is neat and beautiful, easy to maintain, easy to disassemble, and protects the integrity of the aluminum profile as much as possible, which can be recycled at a low cost. However, the angle aluminum welding method of aluminum profile is easy to damage the profile surface, and it is not easy to change the shape after fastening, and the welding cost is high, so it is generally not recommended to use.
Advantages of using aluminum corner extension profiles; Angular aluminum is a commonly used product for architectural decoration. Compared with angular iron, angular aluminum has a prominent advantage that it will never rust and can obtain better strength after aging heat treatment. Therefore, angular aluminum has gradually become a rising star in the construction industry. If anodic oxidized angular aluminum is used, it can further improve the weather resistance and is suitable for use in various indoor and outdoor environments.
